CANID^. 933 



Canidce of which this part is preserved, excepting Leidy's Atnpliicyon vetus 

 (PI. I, fig. 1, Extinct Manimaha Dakota and Nebraska). The nareal trough 

 IS, by comparison, nai-row. The posterior palatal or nareal border is regu- 

 larly concave. The palate is gently concave. 



Sutures. — The preniaxillaries do not reach the frontal bones. The 

 lachrymal is wide at its inferior part and narrows upwards as in the foxes. 

 The orbitosphenoid extends to the vertical line from the postorbital process 

 of the frontal. The contact of the alisphenoid and parietal is extensive. 



Foramina. — The infraorbital foramen opens above the posterior root of 

 the third premolar. The / magnum is wider than deep, and has its superior 

 margin regularly arched. The / conchjloideiun is near to the / lacerum 

 jposteriiis, but is distinct. There is a foramen in the position of the / 

 <;arotideum of the Viverridce on one side; it is wanting on the other, and cf&es 

 not occur in the second skull. I suppose, therefore, that it is abnormal. 

 It is interesting as possibly indicating a tendency to variation in the direc- 

 tion of the civets. The meatus auditorius externus is not enlarged down- 

 wards, and is an oval directed downwards and forwards. The / ])ostgle- 

 noideum, is rather large, and is cut off from the meatus by the anterior rim 

 of the latter. The / ovale is large, and is very near the / lacerum anterius 

 and well posterior to the alisphenoid canal The// rotundum and spheno- 

 orbitale are large, and are only separated by a thin partition. The / orhi- 

 tonasale has the posterior position seen in other species of the genus. The 

 / / palatina are opposite the anterior part of the internal borders of the first 

 tubercular teeth. 



Bentitioit. — Three premolars, two true molars, andiin incisor remain in 

 this specimen. The crown of the incisor is worn; the alveolus of the 

 canine indicates usual size for the tooth. Crown of first premolar simple. 

 Third premolar compressed, with a well-developed posterior cutting lobe. 

 Sectorial robust, rather wide in front, but with the inner lobe small. The 

 tuberculars are large, and wide anteroposteriorly, but not so wide as in 

 G. latidens. The external cingulum is entire on the first, and disappears 

 posteriorly on the second. The cusps are not elevated, and there are a 

 median V-shaped ridge and internal cingulum, on both teeth.
