II, ; III, ; IV, ; V, ; interdigital webbing present between second phalanges of digits II, III, IV; tail uniformly dark brown, scutular hairs short, those of underside longer but not concealing scales. Mammae 1-2 = 6. Cranial. Dorsal contour of skull gently sloping; rostrum elongate, nasals with premaxillary bones parallel-sided, their combined tips slightly trumpet-shaped; zygomatic arches slender, zygomatic plate visible when viewed from above; frontal sinuses little inflated; temporal ridges weak; well defined interparietal bone small (3 x mm); incisive foramina ( x ) extending slightly behind level of metacone of M1; posterior palatal border level with posterior border of last molars; mesopterygoid fossa wide ( mm). Dental. Incisors orthodont, combined cutting edges plane; molars tetralophodont, hypsodont, the cusps opposed, worn crowns deeply dished, 8-shaped; M1 with anterior median flexus, M3 small, the attenuated metacone and hypocone barely distinguishable from each other; lower molar crowns as worn as uppers, opposing cusps oblique; anterior median flexus present; mesolophid, ectolophid and protocunulid defined in m^; m3 nearly twice as large as M3. Measurements. Table 11. Comparisons. Oxymycterus caparaoe can be distinguished by smaller size alone from larger sympatric Oxymycterus rufus or O. hispidus. It is separated from the similar sized southeastern Brazilian O. nasutus Waterhouse (1837) (fig. 30) by paler coloration (table 12) and more projecting rostrum. Comparative morphometries are in table Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Zoologisches Forschungs
