GENUS DYCOTYLES.— F. Cuvier. 



DENTAL FORMULA. 



Incisive =- ; Canine = — ^ i Molar - — t. = 38. 



6 1 — 1 b — 6 



Tusks or canine teeth, projecting slightly, not curved near the points 

 as in the common hog, (Sus,) small, triangular, and very sharp ; molars, 

 with tubercular crowns ; tubercles, rounded and irregularly disposed. 

 Head, broad and long ; snout, straight, terniinated by a cartilage ; ears, 

 of moderate size and pointed ; eyes, rather small, pupil round. Fore-feet, 

 with four toes, the two middle toes largest, the lateral toes quite short, 

 not reaching to the ground ; hind-feet, with three toes, the external little 

 toe of the hog w^anting in this genus. 



The metatarsal and metacarpal bones of the two largest toes on all the 

 feet are united together like those of the ruminantia ; all the toes are 

 protected by hoofs. A gland situated on the back a few inches from the 

 root of the tail, concealed by the hair, discharges an oily foetid secretion. 

 Body, covered with strong, stiff, bristles ; tail, a mere tubercle. 



Only two species are known, both inhabiting the warmer climates of 

 America ; the generic name Dycotyles, is derived from the Greek words, 

 Sis, (dis,) double, and xotuAs;, (kotule,) a cavity ; or double navel, from the 

 opening on the back.
