 from this aspect. The pectoral paddles have seven, and 

 the pelvic five rows of phalangeals. Purchased, 1878. 



R. 1212. Slab showing the ventral aspect of a larger but imperfect 

 skeleton agreeing very closely in characters with the 

 preceding ; from Lyme-Regis. The skull and paddles are 

 fairly well preserved, bat the vertebral column is broken 

 up, and the caudal region wanting. No history.

 skeleton of a small individual probably referable to this 

 species ; from Lyme-Regis. The skull is wanting, but 

 the dorsal and anterior part of the caudal region of the 

 vertebral column, as well as the ribs and abdominal ribs, 

 are beautifully preserved. The limbs of the right side, in 

 a dislocated condition, are also shown, as well as the 

 scapula, imperfect coracoid, and clavicle of the same side. 

 The pectoral limb had eight longitudinal rows, and shows 

 all the characters of the present species. Within the ribs 

 are masses of coprolitic matter marking the position of the 

 stomach and the tract of the intestine. Purchased, 1858.

 a small individual of this or a closely allied species : from
