198 SATJEOPTEEYGIA. 



R. 276 a. A similar but more imperfect specimen ; from Wheatley. 



Egerton Collection. 



31911. A posterior dorsal vertebra, with the arch imperfect; from 

 Shotover. In this specimen, which is as large as the pre- 

 ceding, the depression of the base of the neural canal, so 

 conspicuous in the anterior dorsals, has almost disappeared. 

 The centrum, as in the preceding specimen, has the ter- 

 ' minal faces transversely elliptical, instead of nearly cir- 

 cular, as in No. 41802 d. Purchased, 1859. 



31922. A posterior dorsal vertebra, somewhat imperfect ; from Shot- 

 over. Purchased, 1859. 



47878. An imperfect posterior dorsal vertebra agreeing very closely 

 with the preceding; from Shotover. The post-zygapo- 

 physes are well shown. 



Presented by the Hon. M. Marsham, 1877. 



47878 a. Two still more imperfect dorsal vertebrse, associated with 

 the last. Presented by the Hon. M. Marsham, 1877. 



32777. An imperfect vertebra, probably belonging to the lumbar 

 region ; from Boulogne. Purchased. 



31913. The centrum of a smaller vertebra, probably from the lumbar 

 region ; from Shotover. This specimen closely resembles 

 No. 42496 g, and has its terminal faces elliptical. 



Purchased, 1859. 



31904. A similar and probably associated centrum; from Shotover. 



Purchased, 1859. 



47328. A middle caudal vertebra, probably belonging to this species ; 

 from the Kimeridge Clay of Swindon, Wiltshire. 



Presented by the Directors of the Swindon 

 Brick and Tile Company, 1876. 



R. 1287. Cast of the centrum of an anterior caudal vertebra. The 

 original is from the Kimeridge Clay of Baldon, Oxford- 

 shire ; and, together with eight associated caudals and a 

 few cervicals, is preserved in the Oxford Museum. This 

 specimen is figured by Phillips on p. 372, as one of the 

 types of P. validus. It is absolutely indistinguishable 

 from an anterior caudal of No. 42496, marked g. Length 

 0,057 (2-25 inches), height 0,082 (3-25 inches), width 

 0,099 (3-9 inches). Made in the Museum, 1888.
