Characters. — Another nearly related small form, without a metatarsal 

 gland or tuft, the type specimen of which is in the British Museum. 

 General colour of pelage of upper-parts dark grayish brown, with whitish 

 speckling, but the upper surface of the tail uniformly dark brown ; the 

 individual hairs dark isabelline gray at the base, with a whitish band 

 below the black tip ; under-parts whitish. 



Since several skins of this deer preserved in the British Museum are 

 all of the same colour, it is probable that the dark hue is persistent at all 

 times of the year. Fitzinger states that the hair on the hinder half of the 

 back is devoid of speckling, but this is not the case with the specimens in 

 the British Museum. 



Distribution. — Peru and Bolivia.

 of the upper lip, and continued by a spot on the border of the lower lip ; 

 behind the dusky band another of gray, passing into dark gray behind ; a 

 dusky brown streak down the middle of the face ; a crest of long reflexed
