268 SAUROPTEKYGIA. 



28307. Slab exhibiting the right lateral aspect of the posterior 

 cervical and anterior dorsal region, of the vertebral 

 column and the two humeri of a nearly similar immature 

 individual ; from Lyme-Regis. Thirty vertebrae remain, 

 some five of which are cervical, the latter showing the 

 characteristic junction of the costal with the neura- 

 pophysial facets. As in the posterior cervicals of the 

 type, the two costal facets have coalesced. The humerus 

 is slightly larger than that of the type. Purchased, 1853. 



49202. The skull and anterior cervical vertebrae of an adult indi- 

 vidual ; from Lyme-Regis. The frontal region has been 

 crushed, thus causing the vertical diameter of the orbit 

 to be much shortened ; but in other respects the specimen 

 is fairly perfect. The anterior cervical vertebrae show the 

 characteristic union of the upper costal with the neura- 

 pophysial facet, although the arches have become anchy- 

 losed ; they have a small haemal carina. The characters 

 of the skull accord closely with those of the smaller 

 crushed skull of the type ; and the specimen is indistin- 

 guishable from the skull of P. brachycephalus figured 

 by Sollas, both specimens showing the contracted pre- 

 maxillae, expanding into a spoon-shaped termination, and 

 traversed by a distinct median ridge. The length from 

 the extremity of the premaxillae to the occipital crest is 

 0,291 (11-5 inches). Purchased, 1878. 



31887. The centrum of an anterior cervical vertebra of a larger 

 individual; from Lyme-Regis. The union of the upper 

 costal facet with that for the neurapophysis is very clearly 

 shown. Purchased from the Earl of Enniskillen. 



31883-84, -85, -86, -88, -90 to -98. A number of centra of 

 " pectoral," lumbar, and caudal vertebrae associated with 

 the preceding. Purchased from the Earl of Enniskillen. 



33285. Slab showing three later cervical vertebrae, referred by 

 Owen (and apparently rightly) to the present species ; 

 from Lyme-Regis. These specimens indicate an adult 

 individual, the dimensions of one of the centra being: — 

 length 0,028 (1-1 inches), height 0,038 (1*5 inches), width 

 0,046 (2-0 inches). The centra closely resemble those of 

 No. 28307, but the upper costal facet is less completely 

 connected with the facet for the arch. Purchased, 1858.
