for the temporal muscles are not defined on the frontal bone. The upper 

 border of the anterior nasal aperture is on a line with the canine tooth. 

 The distance between the lachrymal ridges is greater than between the 

 lachrymal ridge of one side and the corresponding central incisor. The 

 distance from the last maxillary molar to the posterior limit of the nasal 

 chamber is less than the distance from the point last named to the end 

 of the long endopterygoids. The palatal ragte are more trenchant, 

 curved, and wider apart opposite the premolars, than is the case with 

 €. brevicauda. 



Teeth. — The number of the teeth is the same as in C brevicauda, viz:

The maxillary central incisors touch their entire lengths.* The lat- 

 eral incisors are very small and are free from both the central incisor 

 and the canine. The first premolar is distinctly caniniform and does 

 not touch either the canine or the second premolar. 



The mandibular second premolar does not touch the third premolar. 

 The distance from the anterior border of the canine to the first molar is 

 3'"'", a distance over ^""" greater than that from the anterior border of 

 the canine to the central incisors.

* G. E. Dobson (Cat. Chir. Br. Mus., 1878) gives this as a character of C. brevicauda. 

 From my examinations, lean not agree with thisVriter. The teeth exhibit a A- 

 shaped space between the cutting edges.
