Ventral pelage Dark Neutral Gray (color 83) basally, with superficial wash of Light Neutral Gray (color 85) or Glaucous (color 80); not sharply set off from dorsal coloration. Mystacial vibrissae long, extending just behind pinnae when laid back alongside head. Ears sparsely covered with short, blackish hairs, not contrasting conspicuously with color of head. Hairs over metapodials and digits of manus and pes dark, but tufts of longer hairs at bases of pedal claws silvery. Pes neither very narrow nor conspicuously broad; digit V long (its claw extending almost to base of claw of digit IV), but apparently nonopposable.

Dorsal profile (in lateral view) distinctively flattened from nasal tips to midfrontal region; anterior margin of zygomatic plate straight and nearly vertical, not conspicuously sloping backward from base. Incisive foramina widest just behind premaxillary/maxillary suture and short (averaging 60% of diastemal length), not approaching first molar alveoli. Palatal bridge broad, smooth (without prominent ridges or grooves), and short (not extending posteriorly behind molar rows); posterolateral pits small, simple, inconspicuous perforations (never large, complex, or recessed in shallow fossae). Mesopterygoid fossa broad, straightsided, extending anteriorly between third molars; bony roof complete or perforated by narrow, slit­like sphenopalatine openings flanking the presphenoid/basisphenoid suture. Parapterygoid fossae narrow, approximately triangular, with shallow (unexcavated) anterior limits. Alisphenoid strut present, separating buccinator­masticatory from accessory oval foramina. Carotid circulation primitive (pattern 1), as indicated by large stapedial foramen, prominent squamosal­alisphenoid groove, and sphenofrontal foramen. Postglenoid foramen and subsquamosal fenestra subequal; tegmen tympani broadly overlaps posterior suspensory process of squamosal. Auditory bullae small, uninflated, flask­shaped; without sharply defined transition between capsular part and bony eustacian tube. Tympanic membrane pars flaccida present, large.

Spectrum Orange [color 17] in fresh material). Upper molars in parallel left and right series, small, pentalophodont, hypsodont when unworn (by comparison with more brachydont congeners), and lacking well­developed cingula and stylar cusps. M1 anterocone divided by anteromedian flexus into subequal anterolabial and anterolingual conules. Paralophs and metalophs (on M1 and M2) connect corresponding labial cusps to mesolophs and posterolophs, respectively, or to median mures, not to opposing lingual cusps. M3 conspicuously smaller than M2 (&lt;50% as estimated by occlusal areas) and usually lacking a distinct lingual fold (hypoflexus). Lower molars similar to upper teeth in general design, but m1 anteroconid often undivided (even in unworn dentitions), and m3 not conspicuously reduced. Molar root formulas unknown (no specimens are available with loose teeth), but M1 and m1 apparently without accessory rootlets.
