The cranial fragment on which the G. nasutus was founded differs from 

 that above described in a somewhat greater compression of the muzzle and 

 greater prominence of the tuberosity behind the inferior part of the /ora/wew 

 infraorhitale exterius. This tuberosity is well marked, while in the muzzle 

 of the G. minutus it is merely indicated. The enamel of the incisors is of 

 a bright bay color ; it is pale waxen in all those of G. minutus. The nasal 

 bones are preserved ; they are distinct, and were continued beyond the line 

 of the anterior border of the incisors. They are convex anteriorly and 

 very shallowly concave behind. They extend a little further posteriorly 

 than the extremities ot the premaxillary bones
