reversed view of the right lateral aspect being also given 

 in the ' Quart. Journ. Geol. Soc' vol. xxxii. p. 359, fig. 8. 

 The occipital region is very imperfect, and portions of the 

 roof of the brain-case are wanting, so as to expose a cast 

 of parts of the brain. The mandible is tightly closed 

 against the palate, so as to conceal the lower teeth. The 

 general contour of the cranium and mandible accords 

 closely with that of the type species, the inferior aspect 

 of the mandibular symphysis having precisely the same 

 oblique upward inclination. The postorbital bar also has 

 the same backward inclination as in the latter. The 

 serration of the posterior borders of the cheek-teeth is 

 well shown ; but owing to this border of the premaxillary 

 teeth being concealed in matrix the serrations are invisible.

Genus LYCOSAURUS, Owen \ 



Incisive teeth apparently s in number, and the cheek-teeth 5 or 6 

 in upper jaw; structure of teeth not shown; contour of skull very 

 imperfectly shown in the type species, but the postorbital bar in- 

 clined downwards and forwards; if the form mentioned below as 

 Uyorhynchus belongs to this genus, the orbits will be directed 

 laterally. Inferior surface of mandibular symphysis nearly vertical, 

 and its lateral surface with a distinct hollow for the protection of 

 the upper tusk. 



Lycosaurus partialis, Owen 2 . 



Syn. Lycosaurus tigrinus, Owen 3 . 



The type species. Attains dimensions considerably exceeding 

 those of JElurosaurus curvimola.
