tion of the inferior surface of the mandibular symphysis ; apparently 

 attains a somewhat larger size than the type species.

R. 855 a. The anterior extremity of the crushed skull ; from the 

 Karoo system of the Gouph district, Beaufort West. The 

 cranium has been flattened by a vertical crush ; but the 

 short interval between the orbit and nares is well shown. 

 There are seen to be five premaxillary teeth on either 

 side ; while in the mandible four teeth are shown in 

 advance of the tusk. The serrations on the posterior 

 border of both the premaxillary and cheek-teeth are 

 clearly shown. Purchased from T. Bain, Esq., 1880. 



49419. The anterior extremity of a rather larger skull apparently 

 referable to this form; from the Gouph district. The 

 internarial septum is broken away, and the teeth are 

 much damaged. Five premaxillary teeth can, however, 

 be seen on either side, the summit of the fifth on the left 

 side showing the serrated posterior border very distinctly. 

 The upper tusk of the right side is much smaller than the 

 remains of the corresponding tooth on the left, and would 

 appear to be a successional tooth. 



Purchased from T. Bain, Esq., 1878. 



iElurosaurus curvimola (Owen 1 ). 

 Syn. Lycosaiirus curvimola, Owen 2 . 



Considerably larger than the type species. Four upper incisive 

 teeth; and the preorbital portion of the skull comparatively short 

 and tapering. The small size of the upper tusk in the type speci- 

 men is not improbably indicative of a female. The resemblance of 

 the skull of this form to that of the type of IElurosaurus was 

 pointed out by Owen in his description of the latter, and now that 

 the division of the nares in that form is known, it seems scarcely 

 advisable to generically separate the present form solely on account 

 of having four in place of five premaxillary teeth.
