Those specimens not collected by him were measured by the collectors G. Heinrich, H.J.V. Sody, J.J. Menden, and H.C. Raven; none took weights and Raven did not measure ear length. We cannot verify the accuracy of the values, especially those obtained by G. Heinrich who collected the specimens from Rurukan in the northern peninsula. In Musser’s experience, Heinrich sometimes included part of the tail when he measured head and body, and sometimes the rump in his measure of tail length; we suspect the former for the Rurukan sample.</paragraph>

) comprising the overfur. The underhairs are soft, fine, wavy, and unpigmented along their entire lengths. The overfur layer consists mostly of wide and flat flexible spines, each with a channel extending along the dorsal surface, and a sharp tip. The base of each spine is unpigmented but the remainder is gray, which ranges in tone from pale gray near the unpigmented base to dark gray distally to the tip. In adults showing molt from old to new fur, the old spines have faded to straw brown, but those in the new layer proliferating through the skin are dark bluish gray. Scattered among the spines are softer thin hairs, each unpigmented except for a gray subterminal band. Guard hairs are inconspicuous because they are scattered throughout the coat and barely extend beyond the overfur layer; each is thin and round with an unpigmented base, long blackish subterminal band, and silvery tip. Overall, the fresh dorsal fur is dark gray or dark bluish gray frosted with white along the back but lightens to gray on sides of the head and body; old, worn pelage fades to pale straw brown.

Hairs forming the underfur are soft, fine, and wavy; those constituting the overfur are narrow, flat, and soft spines, each with a dorsal channel from base to near the tip. Texture of the coat is soft to slightly harsh to the touch but not spinous. Underhairs and overhairs are unpigmented in most specimens, so the ventral pelage, from tip of the muzzle to base of the tail, is overall white and sharply demarked from the gray dorsal coat. A few animals from Temboan show buffy or buffy orange patches on the chest and abdomen.

Fur covering the head of adults is pigmented like that clothing the body; throat and cheeks are white, chromatically indistinguishable from chest and abdomen. Rhinarium and lips are pink. Behind each ear is a crescent-shaped pale gray patch of soft, fine and short hairs that provides a whitish-gray crescent-shaped tuft around the base of each ear. The only obvious facial pattern is formed by blackish-brown eyelids and a circle of darker hairs around each eye, which on some individuals are more expansive and form a mask. All species have an array of mystacial, submental, superciliary, subocular, genal, and interramal vibrissae adorning the head; the longest mystacial extend beyond the ears when laid back over the head (see

Dorsal surfaces of the metatarsal region are either white (covered with unpigmented hairs), or white with small patches of gray speckling; digits are typically white. Conspicuous silvery ungual tufts cover bases of the ivory-colored stout claws. Each naked, dark gray plantar surface is adorned by six moderately fleshy pads: four interdigital mounds (forming a cluster at the bases of the digits), a tiny pimplelike hypothenar, and a short and narrow ridgelike thenar (both are very small and inconspicuous relative to plantar surface). The hind claws are curved and sharp tipped and moderately long relative to the length of the digits and hind foot, proportionally similar to the configuration seen in Sundaic

of braincase breadth; table 6) rostrum is typical; from a lateral view, the rostrum tapers from its highest point level with the zygomatic plates distally to the incisors. The smooth sides are broken near the base of the rostrum by low nasolacrimal capsules that barely bulge beyond the rostral walls (and are hardly evident in dorsal or ventral views). Pointed tips of the nasals overhang the external nares and are either even with or project slightly beyond anterior edges of the premaxillaries; posterior borders of the nasals extend well beyond the premaxillary-frontal suture (by 14

of nasal length). The zygomatic plate is moderately wide, its maxillary root originating posterior to the nasolacrimal bulge and above and in front of the first molar; its anterior margin is typically convex, is usually also inclined, and joins the dorsal maxillary root to form a conspicuous notch between the anterior edge of the plate and lateral side of the skull (as seen from dorsal perspective). The posterior edge of the zygomatic plate sits above the anterior onethird of the first molar. A tall and narrow infraorbital foramen is the usual configuration. The tendon of the superficial masseter muscle attaches to a small bony swelling or roughened raised area on the anteroventral corner of the zygomatic plate. Robust zygomatic arches bow appreciably outward; the maxillary and squamosal roots of each arch are united by a short jugal. The squamosal root of each zygomatic arch originates low on the outer braincase wall and its posterior margin extends as an indistinct ridge along the braincase to disappear well before the occiput.

Its dorsolateral borders are defined by conspicuous ridges that extend along dorsolateral margins of the postorbital region (but never wide enough to form narrow shelves) and to the braincase where they form low but prominent temporal ridges that disappear anterior to the occiput (just before the lamboidal ridges). The otherwise smooth braincase is squarish (as seen from dorsal perspective) and deep (as viewed from the side) with a domed roof. A rectangular portion of the parietal drops below the dorsolateral margin of the braincase almost to the top of the zygomatic root; this projection and the squamosal form the wall of the braincase. The inner sidewalls of the braincase are smooth, without squamosalalisphenoid grooves. Sides of the braincase are vertical from the temporal beading to squamosal roots of the zygomatic arches. The occipital region is moderately deep and roofed by the interparietal in the middle and dorsal segment of the exoccipital on either side. The boundary between squamosal and exoccipital is marked by prominent lamboidal ridges. The posterior wall of the occiput is vertical (in lateral view) and even with the posterior boundaries of the occipital condyles. The squamosal above each auditory (ectotympanic or bullar) capsule and just anterior to the lamboidal ridge is complete (not penetrated by a subsquamosal foramen).</paragraph>

Except for a pair of grooves that increase in depth from front to back, the bony palate is smooth, its posterior margin projects well past the third molars to form a bony shelf. A pair of large posterior palatine foramina penetrate the palate at the maxillopalatine suture opposite either first or second upper molars. Maxillary molar rows are either parallel or bow medially toward the back of the bony palate. The mesopterygoid fossa is narrow and its dorsolateral walls are perforated by two wide and moderately long sphenopalatine vacuities that expose the medial borders of the presphenoid and basisphenoid.

The posterolateral and posterior edges of the plate converge behind the foramen ovale to form a wide and smoothly rounded ridge, which defines the anterolateral border of the spacious medial lacerate foramen separating the pterygoid plate and posterior margin of the alisphenoid from the ectotympanic bullar capsule. Just medial to this pterygoid ridge is a deep groove for the infraorbital branch of the stapedial artery. The spot where the artery leaves the groove and passes to the dorsal surface of the pterygoid plate defines the posterior opening of the alisphenoid canal.

, most of the alisphenoid bone extends to the base of the hamular process without meeting a generous horizontal pterygoid plate (panel A) and the entire outer surface of the alisphenoid is exposed. Aside from tiny scattered nutrient foramina, only two major openings are present in the alisphenoid: the anterior opening of the alisphenoid canal forms a small round or irregular aperture anterior to the much larger and spacious foramen ovale. Emerging from the latter is a shallow trough for the masticatory and buccinator divisions of the maxillary nerve. Between the foramen ovale and the large middle lacerate foramen is a shallow groove in which the infraorbital artery courses. In some specimens, a continuation of the groove can be detected between the anterior rim of the foramen ovale and the anterior opening of the alisphenoid canal (

B–D). This disposition of foramina and grooves indicates that the stapedial artery branches from the common carotid and enters the periotic region through a large stapedial foramen. The infraorbital branch of the stapedial artery exits the pteriotic through the middle lacerate foramen, courses in a short groove (between middle lacerate foramen and foramen ovale), and continues on the outside of the skull at the base of the hamular process to disappear into the braincase through the anterior opening of the alisphenoid canal from which it emerges to course through the anterior alar fissure into the orbit. The supraorbital branch of the stapedial is absent; the arterial supply to the orbit is furnished by the distal part of the infraorbital branch. This circulatory plan is common among murines (

). On the dorsal rim of the ramus behind the molar row, the coronoid process is a minute triangular projection, and the long rim between it and the large and long condyloid (articular) process is either straight or slightly concave (very shallow sigmoid notch). The posterior margin of the dentary between the large condyloid and angular processes is deeply concave (outlining a half circle). A large bulge on the side of the dentary behind the coronoid process and even with the dorsal rim marks the posterior termination of the incisor sheath (alveolus). Masseteric ridges on the lateral surface of each dentary are pronounced.

Located at the front of the first molar is a chunky anteroconid composed of large anterolabial and anterolingual cusps (no anterocentral cusp was found on any of the specimens) that have merged to form a large oblong lamina (without discernable cusp boundaries in some specimens, but clearly formed from two cusps in others) either slightly or much narrower than the lamina behind it. None of the molars bear anterior labial cusplets; various frequencies of occurrence of posterior labial cusplets on all molars along with anterolabial cusps on the first and second molars comprise minor components of the occlusal surface.

used in analyses of morphometric traits come from four places and each analytical sample is small. There is insufficient material and geographic coverage for any serious analysis of geographic variation in external, cranial, and dental traits. We can report that features of fur coloration along with lengths of head and body, tail, hind foot, and ear among adults show hardly any differences from place to place other than that ascribed to individual, age, and sexual variation. Nor do definable groups emerge when cranial and dental measurements are subjected to principal-components analysis. The distribution of specimen scores for the samples from Rurukan, Gunung Masarang, Tondano, and Temboan projected on the first and second principal components (not illustrated here) intermix to form a single large cluster. If significant geographic variation exists within the range of
