 Pecari angulatus. Miller, List N. Amer. Mamm. p. 383, 1912. 



Typical locality Guadelupe Valley, Texas. 



General characters those of B. tajacu, but palate with 

 sharp ridge reaching from first premolars to bases of sockets 

 of canines ; nasal bones more angulated in median line ; last 

 upper premolar quadrangular, with four main tubercles and 

 intermediate tubercles ; molars wrinkled ; sides of cranial 

 rostrum deeply excavated above jpremolars. When only one 

 form of peccari with this type of skull and dentition was 

 known, the writer regarded it as a race of B. tajacio, now 

 that a number are recognised, it is convenient to allow 

 specific rank to this type, of which the local races are 

 distinguishable as follows : — 



A. Size larger. 



a. Shoulder-stripe white ; sides o£ body black 



and white -D. a. angulatus. 



b. Shoulder-stripe yellowish ochery, narrow ; 



sides greyer D. a, humeralis. 



c. Shoulder-stripe broad ; sides whitish D. a. yucatanensis. 



d. Shoulder-stripe indistinct, very narrow ; sides 



grizzled grey D. a. crassus. 



e. Shoulder-stripe indistinct; sides mixed greyish 



and brownish black B. a. sonoriensis. 



f. Shoulder-stripe wide and tawny B. a. crusnigrum. 



B. Size smaller; sides grizzled black and buff B. a. nanus.
