﻿LEIDY'S DESCRIPTION OF REMAINS OF EXTINCT MAMMALIA. 171 



Anomodon Snydeki, Le Conte. Am. Journ. of Science and Arts, 2d ser. v, 106. 



In association with the remains of Procy on prisons, just described, there was found 

 a curious tooth, which Dr. Le Conte has supposed to be the left superior canine of a 

 large Insectivorous animal. It is quite peculiar in form ; and its affinities I am at 

 present unable to determine. 



The tooth is compressed to a remarkable degree, and on the inner side for the greater 

 part of its length is depressed, so that a transverse section except near the apex of 

 the crown would be reniform. The crown is curved conical, and is most convex ex- 

 ternally. Posteriorly its outer and inner surfaces are separated by a feeble ridge ; and 

 internally about half way towards the base it is furnished with an anterior and a 

 posterior tubercle, of which the former is lower than the other. 



The fang at the broken border of the specimen is nearly half an inch broad and is 

 less than two lines thick. In consequence of the depression of its inner wall, the 

 pulp cavity has a curved linear form, thus (. 



In its perfect condition the tooth has apparently been in the neighborhood of an inch 

 and a half long, and the base of the crown measures five lines broad and one and 

 three quarter lines thick.
