Cranial and Dental Characters. 

 The skull is not so elevated between the orbits as in C. anthiis, 

 though more so than in C. aureus, but, as in the latter, the anterior 

 palatine foramina are small. The shape of the third upper premolar 

 agrees with that of C. aureus {i. e. the tubercles behind the principal 

 cusp are very small), and differs from that of C. anthus.
