Rtrnarkx. — Only two specimens from the type locality, both young 

 adult males, are in the collection. The skulls resemble two from Hue-

 animal the skull of the female is decidedly larger than the male — being 

 longer, and broader across the rostrum. The skins are (|uite diflferent. 

 those from Huehuetan being darker, the black dorsal stripe present an- 

 teriorly (from occiput to shoulders); rump an<l hind legs blacker; nose 

 blackish; light rings on bristles on anterior part of body (particularly 

 on head) ochraceous or yellowish fulvous instead of whitish, giving a
