is one of three smallbodied spiny rats within the Rio Juruá basin, with short ears, small hind feet, and proportionately long tail (tables 60 and 64). The tail is bicolored, dark brown above and cream to white below; the scales are relatively small, but not completely hidden by the hair. The overall color of the body is between Sanford’s Brown and Auburn (Ridgway, 1912), coarsely streaked with varying amounts of black both on the dorsum and sides; as with other species of spiny rats, the dorsum looks darker, especially on the rump, due to the presence of the heavy dark brown aristiform hairs. The venter and chin are pure white; in 12 out of

the sides of the upper lips, sometimes confluent with a spot at base of vibrissae, are also white; the pure white of the inner surface of the hind limbs extends across the ankle along the hind foot in 7 of the 13 Rio Juruá specimens (the dark tarsal bank is incomplete) e color of the hind foot is yellowishwhite rather than the pure white of the venter and inner thighs.

The skull is small and delicate, with a relatively long and narrow rostrum (figs. 138 and 139), and a beaded supraorbital ledge above the orbits that extends posteriorly as a weakly developed ridge on the anterior parietals. The postorbital process of the zygoma is obsolete (see da Silva, 1998: fig. 11). The floor of the infraorbital foramen is smooth, lacking a ventral canal. The incisive foramen is ovate to slightly lyrate in shape, with posterolateral margins flat or weakly flanged, at best outlining only a shallow groove in the anterior palate (fig. 140). The maxillary portion of the septum is dorsoventrally compressed posteriorly and narrow anteriorly, visible over almost half the length of the foraminal opening, and fully connected to the premaxillary portion, which is broad and usually about half the length of the foramen. The vomer is not visible on the ventral margin of the septum. The palate is smooth, without a median ridge. The mesopterygoid fossa is long and narrow (fig. 141), with an acute angle of indentation into the posterior margin of the palate averaging 61°, and penetrates deeply, often to the middle of M2. The cheekteeth are remarkably small, averaging only 7.5 mm in length. All upper teeth typically have three folds, although only two folds may be found on M

locality at Altamira, and from 6 individuals from the upper Rio Urucu. The diploid number is 40, the fundamental number 56, and the karyotype itself is figured in da Silva (1998). The autosomal complement includes seven pairs of mediumsized to small metacentrics and submetacentrics with one pair minute, two pairs of moderately small subtelocentrics, the smallest of which bear secondary constrictions on the long arms, and three pairs of mediumsized and seven pairs of small acrocentrics. The Xchromosome is a moderately small acrocentric and the Y is a small acrocentric. This complement is identical to that of
