162 SAUR0P1ERYGIA. 



vertebrae with no notch between the pre- and postzygapophyses of 

 the same side, and their centra extremely short. 

 Bab. Europe (England). 



P. 34. Cast of a slab containing the nearly entire skeleton, of which 

 the dorsal aspect is exposed. The original, which is the 

 type, was obtained in 1848 from the Upper Lias of Ket- 

 tleness, near Whitby, Yorkshire, and is preserved in the 

 Museum of Science and Art, Dublin. It is figured by 

 Carte and Baily in the ' Trans. R. Dublin Soc' vol. vi. 

 pi. vi., the skull and the last (27th) cervical vertebra 

 being figured in pi. vii. ; and also by Haughton in his 

 'Manual of Geology/ 2nd ed. fig. 38, p. 273 (1866). 

 Length of skull 1,020 (40 inches). Dimensions of 27th 

 cervical vertebra: — length of centrum 0,061 (2'4 inches), 

 height 0,112 (4*4 inches), width 0,114 (4'5 inches). In 

 the present state of the cast, a fibula is placed in the 

 right pectoral limb in place of the ulna, and in the 

 figures there is also some misarrangement of the limbs. 



Purchased, 1880. 



R. 1008. An anterior cervical vertebra ; from the Upper Lias of 

 Whitby, Yorkshire. A considerable portion of the left 

 side of the centrum is wanting. This specimen indicates 

 a smaller individual than the type ; the dimensions of the 

 centrum being, length 0,037 (1*45 inches), height 0,086 

 (3'4 inches). Its resemblance to the imperfect larger and 

 later cervical of the type species figured by Meyer in the 

 ' Paheontographica,' vol. vi. pi. v. figs. 1, 2, is so close as 

 to show not even specific distinction. The costal facet, 

 although somewhat badly preserved, shows its division 

 very clearly; and the characteristic features of the arch 

 are also well exhibited. No history. 



R. 1365. Two bones, which are apparently chevrons of this species ; 

 from Whitby. These specimens are of very large size, 

 and have facets for mutual articulation. So far as can 

 be seen from the cast, they apparently accord with the 

 chevrons in the anterior caudal region of the type. 



No history. 



40123. A smaller bone of similar type; probably from Whitby. 



Purchased. 



47154. An immature fibula probably belonging to this species ; 

 from the Upper Lias of Kingsthorpe, Northamptonshire.
