280 SAUROPTERYGIA. 



R. 1395. Slab showing one side of a left ischium agreeing nearly 

 in relative size with the preceding specimen; probably 

 from Street. No history. 



R. 879. A right (?) ilium ; from Lyme-Regis. Agrees approxi- 

 mately in size with the ilium of No. 28304. No history. 



R. 1393. A considerably larger ilium ; locality unknown. Indicates 

 an animal of the approximate size of P. rostratus. 



No history. 



28323. The left femur of a large species ; from Lyme-Regis. This 

 specimen might belong to an immature individual of 

 Thaumatosaurus arcuatus, since it agrees in contour, and 

 also in its extremely rough articular surfaces, with the 

 corresponding bone of that species. Purchased, 1853. 



R. 1390. The left femur of a large species ; from Lyme-Regis. 

 Apparently agrees well with the femur of P. rostratus. 



No history. 



41252. The associated right and left femur of a form agreeing 

 approximately in size with P. dolichodirus ; from the 

 Lower Lias of Tewkesbury, Gloucestershire. 



Purchased, 1869. 



R. 671. A slightly smaller left femur of the general type of the 

 preceding specimens ; from Lyme-Regis.

32393 b. A right femur apparently associated with the preceding ;

Purchased. 



32393 d. A rather longer left femur ; from Lyme-Regis. 



Purchased. 



R. 1388. A left femur ; probably from Street. This specimen, 

 which is longer than the last, is remarkable for the great 

 prominence of the rugosity for muscular attachment at 

 the proximal extremity of the dorsal surface. No history. 



R. 1387. Slab showing the ventral aspect of a left femur of similar 

 type ; from Street or Lyme-Regis. No history. 



32393 e. An imperfect right femur of the same general type ; from
