LASIOPYGA 363 



edge of forehead ; back of head and hind neck blacker, the hairs banded 

 with black and ochraceous, the black predominating, just as the ochra- 

 ceous predominates on fore part of head ; sides of head, hairs long, 

 banded with black and buff, paler than head; broad white collar on 

 both sides of neck not meeting on back and gradually lost in white of 

 chest; fur below collar on upper back, much worn in places, purplish 

 black, hairs banded with black, white and ochraceous ; rest of upper 

 parts speckled with burnt sienna and black, this color extending over 

 the flanks ; arms and hands black, above elbows speckled with white ; 

 legs blackish gray white speckled; chin, throat and upper part of the 

 breast buffy white; chest to lower part of abdomen gray faintly 

 speckled with white, as are also the hairs on the chest ; hairs across 

 pubic region buff; inner side of thighs, and upper parts buffy white; 

 pubic spot ferruginous ; feet black ; tail at base burnt sienna and black 

 like back, remaining part black ticketed with white, except on a few 

 inches from tip ; ear tufts on fore part of ear yellowish white, on 

 hinder part buff not banded. Mr. Pocock states that the tufts are 

 banded, but it did not appear to me that they were. The tufts exist 

 only on one ear, and there is a break on the one remaining, the two 

 parts being of different colors, and all the hairs composing them were 

 unicolor. Ex type British Museum.
