Ears are small and rounded, internally covered by short golden hairs and externally by brown hairs. The dorsal part of the muzzle is slightly lighter than the rest of the head. Vibrissae are long and thin; mystacial, supercilliary, and genal vibrissae reach the mid-portion of the pinnae; all vibrissae are buffy-brown colored. There is also a genal vibrissa 2 (sensu

a). In the M1 the procingulum is anterior-posteriorly compressed and labially displaced. There is no evidence of anteromedian flexus on the enamel anterior wall but an inconspicuous dentine indentation can be ascribed to this structure. The procingulum is lingually projected by a presumptive protostyle and a cingulum that externally reaches the protocone enclosing the protoflexus. The general morphological configuration and orientation of the procingulum of the M1 are achieved by a reduced anterolingual conule and a presumptive parastyle fused and projecting the anterolobial one. The areas of proto- and hypocone are subequal and bulbous; the same is true for the areas of para- and metacone. The hypocone is slightly labially recessed with respect to the protocone; the hypoflexus is wide, scarcely penetrates the molar midline, and has a corrugated base. The lingual margin of the M1 between proto- and hypocone is ridged by a cingulum that closes the hypoflexus transforming it into a basin. Although wear erases occlusal structures in the intermediate area between para- and metacone, an indication of a narrow but long mesoloph fused with a paralophule is distinguishable. At least in this wear stage, the posteroloph is fused to the metacone. The M2 general configuration is very similar to the comparable portion of the M1. The procingulum is well developed, labially and lingually closed by sharp cingula. The hypocone is also recessed with respect to the protocone; a presumptive enterostyle is present. The mesoloph-paralophule development is like those in M1. A posteroloph directly backwards is independent of the metacone. The M3 is notably reduced, cylindrical in outline, and seems to have only one root. The occlusal morphology suggests the persistence of solely the proto- and paracone areas, being the posterior portion of this tooth deeply compressed.

b). The enamel is thick but there is a good amount of exposed dentine. In the m1 the procingulum is clearly transversally compressed and remains as a narrow structure on the labial sector of the tooth without evidence of an anteromedian flexid. The proto- and hypoconid look like enamel cusps without wear; meta- and entoconid are bulbous and subequals in size. The hypoflexid is wide, short, and slightly labially closed by a weak cingulum. On the posterior face of the metaconid a short mesolophid is present. The posterolophid is well developed. One of the most peculiar characteristic in the m1 morphology is the compression displayed by the lingual cusps and their projection like peninsulas on the lingual margin. The m2, slightly shorter than m1, is rectangular in outline and has the basic pattern of the m1. The posterolophid is short and directed backwards. The m3 is comparatively reduced but not as the upper one, with a greatly reduced entoconid and a posterior enamel lake produced by the obliteration of the posteroflexid.

:49), less developed between third and fourth. Hemal processes starts on fourth vertebrae, becoming most pronounced between fifth and sixth, and then diminishing along the next ten vertebrae. The tuberculum of the first rib articulates with the transverse process of both the seventh cervical and the first thoracic vertebrae. The sternum consists of an anterior manubrium, four sternebrae, and a posterior xiphoid process. The humerus lacks an entepicondylar foramen; the supratrochlear fossa is perforated. The innominate has a well developed femoral tubercle positioned cranially to the acetabulum; the acetabulum is small and rounded; the inferior and superior glutear fossa of the ilium are divided by a rounded lateral ridge. The femur has a small head and a long and narrow patellar fossa; the condyles are slightly rounded in contour.

The mid-shaft diameter is slightly less than one-half of the overall length. Dorsal and ventral grooves are deep and extend beyond half the length of the body. The crater rim is apparently uniform; but unfortunately the apical portion of the penis, including the bacular mounds, is damaged precluding the possibility of an accurate description. In appearance, lateral bacular mounds are not visible in external view; the medial bacular mound is slightly larger than the lateral ones. The proximal baculum is short, stout, and triangular in appearance, with a laterally flared base. The base has a distinct and deep median notch. The shaft is short and wide. The cartilaginous distal baculum is small, with two laterals and one medial digit.</paragraph>

The former has partially convergent interorbital region (hourglass in the latter), shorter rostrum (longer), well on inflated nasolacrimal capsules (less conspicuous), more rounded braincase (more squared), rhomboidal and smaller interparietal (oblong and larger), longer and more robust molars (shorter and slender), broader incisive foramina (narrower), sphenopalatine vacuities present as fissures (absent, roof of mesopterygoid fossa completely ossified), large posterior openings of the alisphenoid canal on parapterygoid plates (small), and slightly opisthodont upper incisors (proodont). In addition, specimen USNM 522416 has the tail tuft white while that of MACN 20253 is dark brown.
