11280. Fragment of* Lias containing a smaller tooth probably 

 belonging to this species ; from Lyme-llegis. 



ManieU Collection. Purchased, 1838. 



R. 264. Three teeth probably belonging to large individuals of the 

 present species ; from Lyme-Regis. ' These teeth appear 

 to be very similar to those in the large skull described by 

 Owen. Egerton Collection. Purchased, 1882. 



28319. Slab exhibiting the right lateral aspect of the nearly entire 

 skeleton of a medium-sized individual ; from Lyme-llegis. 

 The pelvic limbs and the greater part of the caudal region 

 are wanting. The skull and greater portion of the ver- 

 tebral column are fairly well preserved ; but the distal 

 extremities of the pectoral paddles are absent. The tall 

 neural spines of the dorsal vertebrae, and the broad pectoral 

 paddles show the characteristic features of the species. 



Purchased, 1853. 



28305. Slab showing the ventral aspect of a medium-sized imperfect 

 skull, together with fragments of the pectoral girdle and 

 limbs, and some of the abdominal ribs, probably belonging 

 to this species ; from Lyme-Regis. The teeth and frag- 

 ments of the paddles agree with typical examples. 



Purchased, 1853. 



R. 1071. Slab showing the left lateral aspect of the imperfect 

 anterior portion of the skeleton of a somewhat smaller 

 specimen apparently belonging to this species ; from Lyme- 

 Regis. The skull, left coracoid and pectoral limb, together 

 with the anterior portion of the vertebral column, are 

 preserved. No history. 



The following young skeletons exhibit all the characteristic features 

 of the present species, but it is possible that some may be spe- 

 cifically distinct. 



R. 1072. Slab exhibiting the ventral aspect of the crushed skull, 

 and the left lateral aspect of the greater portion of the 

 rest of the skeleton of a small individual ; from Lyme- 

 Regis. The columella is noticed by A. Smith Woodward 

 in the ' Proc. Zool. Soc' 1886, p. 408. Both the pectoral 

 and pelvic limbs of the left side are shown. The pelvic 

 paddle is of the usual characteristic width, but is relatively 

 larger in proportion to the pectoral than is usually the 

 case. No history. 



R. 1073. Slab exhibiting the left lateral aspect of a small skeleton;
