R. 1087 a. The cranium and the anterior part of the axial skeleton, 

 {Fig.) and various dorsal scutes ; from the Upper Lias of Whitby, 

 Yorkshire. This specimen appears to be the one dis- 

 covered by Captain Chapman in 1758, and figured in the 

 Phil. Trans, for that year, pis. xxii. and xxx., and should 

 thus be regarded as the type of the species. Originally 

 the specimen was curved laterally as in the figure, but 

 the head was subsequently chiselled oat and placed in its 

 present position. When figured some of the caudal ver- 

 tebras remained, but these were lost in extraction. 



Presented by the Council of the Royal Society. 



R. 324. The hinder portion of an immature cranium, apparently

47157, A large portion of the mandibular symphysis ; from the 

 Lias of Greens-Norton, near Towcester, Northamptonshire.

 sponding portion of the type specimen ; the splenial 

 element is long and narrow.
