Diagnosis. — Skull small, tooth-rows short, ears small. 



U. hilohatum and thomasi. — The difference between these two 

 species will be pointed out below, p. 221. 



Hairing on limbs and interfemoral. — Forearm densely haired 

 for the proximal two thirds of its upper surface. A tuft of 

 short hairs on the metacarpal of the pollex. Upper side of tibia 

 and foot distinctly haired. Interfemoral very short-haired, its 

 hinder margin almost naked. 



Colour. — General impression brown, varying in shade ; four 

 facial stripes, a dorsal stripe. There are two colour extremes, 

 a dark brown and a light brown, but the contrast between them 

 is by no means great. 



Dark-coloured examples (many skins, all of fully adult in- 

 dividuals, teeth unworn or slightly worn ; localities : Colombia 

 (Oali ; Santa Marta), islands ofi' Panama, Chiriqui) : — Upper side 

 dark brown, darker than Ridgway's Front's brown ; base of hairs 

 on hinder back approaching drab, on the neck lighter, varying 

 from light drab to wood-brown or ecru-drab. Under side a dark 

 shade of drab. Supraorbital and infraorbital stripes broad, 

 whitish. A narrow whitish longitudinal stripe from the occiput 

 to the interfemoral ; front half of the stripe sometimes very 

 indistinct or quite obliterated. A more or less distinct narrow 

 whitish margin to the ears. 



Three examples (Chanchamayo, Peru, and Brava I., W. of 

 Panama ; adults, with unworn or very slightly worn teeth) are 

 noticeably darker : upper side sooty brown, under side dark smoky 

 grey. 



Lighter-coloured examples (two skins : Egas, Amazonas, and 

 Valencia, Venezuela ; adults, with unworn teeth) : — Upper side 

 Front's brown (one skin) or mars-brown washed with russet (the 

 other), base of hairs wood-brown ; under side light drab. Facial 

 stripes, doi'sal line, and ear-edgings as usual. 



Individuals from different localities. — Specimens have been 

 examined from localities dotted over practically the whole area 

 from Para, Amazonas, and Pern in the south, to Costa Rica in 

 the north. I am unable to see any differences, in the skull, teeth, 

 or external characters, between individuals from all these localities. 

 The subjoined table of measurements (p. 219), in which the 

 specimens have been arranged according to their geographical 

 habitat, shows that also the dimensions are the same.
