CEEODONTA. 363 



nearly complete dentition. The muzzle is contracted and is rather short ; 

 the zygomata are widely expanded. The pi-emaxillary extends well poste- 

 riorly along the nasal, but it does not probably reach the frontal bone, 

 which is lost from the specimen. The maxillary is contracted behind tlie 

 canines. The molars arise from it in a ridge which commences above the 

 fourth premolar. The free part of the bone presents an angle downwards 

 just beyond the maxillary, and posterior to this point has a thin inferior 

 border without the bevel indicating the insertion of the masseter muscle 

 usual in carnivora. The maxillary projects posteriorly in a free angle sep- 

 arated from the base of the pterygoid process. The posterior extremity of 

 the molar is a little anterior to the glenoid cavity, and has a horizontal internal 

 expansion The superior border of the bone has a very slight postorbital 

 angle. The glenoid cavity is wide and deep. Both the preglenoid and 

 postglenoid crests are large, and are most elevated externally. The meatus 

 auditorius externus is small, and is closed below by the posttympanic pro- 

 cess without visible tympanic bone. The posttympanic is not coossiiied 

 with the postglenoid process, but is in contact with it. Just interior to tlie 

 meatus the posterior face of the former becomes somewhat tuberous. It 

 has a free superior border, which for a short distance forms the posterior 

 boi'der of the zygomatic fossa. I do not see postglenoid or postzygomatic 

 foramina. 



The mandible is distinguished for its long and slender rami and sym- 

 physis. The inferior border is gentl3^ convex, and the symphyseal portion 

 is in the line of the remaining part of the rami. The length of the sym- 

 physis is unusual, being one-third of the total to the base of the condyle. 

 Its inferior face is distinctly separated from the lateral face by an obtuse 

 angle. The condyle projects much beyond the angle, and is quite large. 

 Its face looks upwards and backwards. The angle is shallow and little prom- 

 inent, its posterior border extending obliquely forwards. Its thin interior 

 edge is directed somewhat obliquely inwards, though not distinctly inflected. 

 The base of the coronoid process is very wide, equaling the length of the 

 inferior molar series, omitting the first premolar. Its anterior border slopes 

 obliquely backwards, and is obtusely rounded to the summit. The latter 

 is not elevated and is very obtuse. The posterior border descends obliquely
