Type of the species in the Paris Museum. 
This species is larger than the other Microcedi. Its skull differs 
from those of M. myoxinus and M. minor by not having the defects 
of ossification in the palate, and by the upper molars having a more 
marked external cingulum; also the fifth cusp of the last inferior 
molar is quite rudimentary. It differs also from all the other M:- 
crocebi in the great length of the inferior incisors, and from all but 
M. typicus in the long and canine-like first upper premolar. This 
is longer, however, than even in M. typicus.
