new Wild Dog from the Bogota Cordillera. 371 



It may be called 



Cerdocyon apottinaris, sp. n. 



A small stoutly built Cerdocyon, with very robust teeth. 



External characters much as in C. thous. General colour 

 above coarsely grizzled black and white, with a suffusion of 

 buffy. Sides dull buffy. Belly buffy whitish. Back of ears 

 little darker than head, their inner surface and edges, and a 

 large patch behind them buffy. Lips and chin black. A 

 white patch on throat. Limbs buffy, greyish externally, 

 clearer buffy internally ; hands and feet black, more or less 

 grizzled proximally. Tail with the usual dorsal and terminal 

 black-tipped hairs. 



Skull short but very stoutly built; its length slightly 

 exceeding that of C aquilus. Bangs, of Santa Marta, less 

 than that of the Brazilian C. brasiliensis, Schinz. Muzzle 

 proportionally short and broad, the combined transverse 

 breadth of the incisors unusually great. 



Teeth stout and heavy throughout. Canines thick. Pre- 

 molars broad. Carnassial and molars large, and so rounded 

 as to give them an unusually large area, even as compared 

 with forms in which direct measurements make the teeth 

 appear larger — e. g., C. mimaas. Space between m 1 and m 2 

 reduced to a narrow crack.

This wild dog differs markedly from all its allies by its 

 short stoutly built skull and remarkably heavy teeth. I have 

 much pleasure in connecting with it the name of the 

 enthusiastic naturalist to whom we owe its discovery.
