animal 7. Fig. 4 represents an unusually-arched tooth, which I 

 refer to the same species, believing it to have held the place of 

 a quasi-canine tooth at the intermaxillary suture. The lateral line 

 with the coalescing strise is very remarkable (see fig. 5). This 

 species is evidently much allied to that described by Cuvier, which 

 is now called T. Cadomensis. 



Finally, the straight or very slightly-arched conical teeth, figs. 

 9 and 10, remain for consideration. Their cross section is oval; 

 the striae are fine, somewhat flexuous, and discontinuous. They 

 seem not to be of ichthyosaurian, but may be of plesiosaurian 

 analogies; or, finally, they may be long teeth at the inter- 

 maxillary suture, which are sketched in Diagram XLIV. of Teleo- 

 saurus brevidens.

Teleosaurus brevidens, Diagram XLIII. The length of the 

 head from the occipital condyle to the end of the beak is thirty 

 inches ; extreme breadth over the parietal region, ten. Regarded 

 from above, the parietal crest makes a strong division between 

 the large oblong lacunae, usually called temporal fossae. In front 

 of these the smaller oval, obliquely-directed orbits are separated 

 by the rhomboidal frontal bone, much pitted, the posterior suture 



y These teeth agree in their slender shape and feeble carination with those of 

 Teleosaurus Cadomensis. (Cuv. Ossem. Foss. t. vii. fig. 10, u, 12.)
