DICOTYLES FOSSILIS. 



Plate XVII. Pros. 13, 14. 



Capt. Bowman's collection of Ashley fossils contains specimens of the crowns of the two 

 back molar teeth of the lower jaw, represented in figures 13, 14, Plate XVII, which have 

 almost the same size and form as the corresponding teeth of the collared Peccary Dicottjles 

 torquatus. The collection further contains fragments of two upper molar teeth, which had 

 about the same size as those of the Dicotj/Ies labiatus. The specimens apparently indicate 

 a different species from the extinct Dicoti/ks compressus of the Western States, and they 

 perhaps belonged to a species different from the recent ones, but the remains are insufficient 

 to determine this question positively.
