New Mammals from Santa Marta, Colombia. 165 



molars and premolars ; in the two smaller upper premolars being distinctly 

 quad ri tubercular and quadrate ; in the form of the small anterior lower 

 premolar. From T. any Hiatus it can be distinguished by nasals not being 

 angulated in the middle line and molars not being wrinkled. From both 

 T. angulatus and T. tajacu it differs by being shorter, lower, and wider, 

 and by the larger molar and premolar teeth. 



Measurements. The type, (J 1 adult: head and body, 1075; hind foot, 

 170 ; ear from notch, 75. 



Skull : basal length, 186 ; zygomatic width, 95.4 ; width between orbits, 

 50; width across postorbital processes, 71.4; width of palate at forward 

 alveoli of last molars, 23 ; greatest length of single half mandible, 156; 

 length of molar series (molars and premolars, alveoli) upper, 67.8; 

 under, 74. 



Remarks. Mr. Brown has thus far sent but one specimen, the type, a 

 fine old male skin and skull. This specimen is, however, so different 

 from either T. tajacu of southern Brazil or T. angulatus of Texas that I 

 feel justified in separating it. Whether it is a species or only a race of 

 T. tdjacu can, of course, not be told without much more material than is 

 now available. 



When Prof. Cope named the Texan peccary angulatus * he irrevocably 

 restricted the Linnsean name tajacu to the peccary of southern Brazil. 



Through the kindness of Mr. Witiner Stone, I have been able to com 

 pare my Santa Marta skull with two of Prof. Cope's original southern 

 Brazil skulls that had come into the collection of the Academy of Natural 

 Sciences.
