Tayassu angulatus crassus subsp. nov. 



Tape from Metlaltoyuca, Puebla. No. 92,900, $ yg-ad., U. S. Nation 

 al Museum, Biological Survey Collection. February 1, 1898. E. W. 

 Nelson and E. A. Goldman. Original No. 12,127. 



Character*, Similar in general to angulatus but larger; pelage very 

 much coarser, the individual bristles exceedingly large and rigid; black 

 dorsal stripe illdefined or obsolete; general color grizzled gray, much 

 paler than angulatus; hind legs grizzled black and fulvous; skull longer; 

 molariform teeth narrower; anterior opening of antorbital foramen be 

 tween 2d and I5d premolars (instead of between 3d premolar and 1st 

 molar as in angulatus). Front of underjaw (seen from below) narrower, 

 flatter, and less swollen in front of forks of rami. Crown of 1st upper 

 premolar narrower and more slender; crown of last lower molar longer 

 and narrower. 



Rtmarks. Only two specimens from the type locality, both young 

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

 huetan, Chiapas, of which both sexes are at hand. In the Huehuetan 

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

 longer, and broader across the rostrum. The skins are quite different, 

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

 teriorly (from occiput to shoulders); rump and 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 

 very different color to the head; bristles larger largest of all. 



Measurements. Type ( $ yg-ad.): total length 9.50; tail o4; hind foot 

 208.
