Skuli. Very similar to that of J\Iiis decumanus and an illus- 

 tration of the one might almost do duty for the other, indeed, 

 were it not for the striking external features one would almost 

 feel inclined to regard the two as identical. Tlie main cranial 

 differences as shown by my specimens respectively are as 

 follows : — In M. villosissivuis the foramen magnum is A shaped 

 above and is deeper or as deep as wide ; the profile of the skull 

 exhibits a greater arch and the nasal portion is more bent 

 down, the interorbital breadth is somewhat less and the anterior 

 palatina foramina are very long and narrow, extending to nearly 

 between the centres of the first molars. 



Teeth. The molar series are set closer together than in M. 

 decumanus, but as both the skulls of M. villosissimus are of aged 

 examples the teeth are worn down and much of their character 

 obliterated.
