FISHES AND MARINE ANIMALS. 265 



paddle has been about ten inches, including the bone that looks like 

 a handle. Behind the handles of the two small fins, are two flat 

 oblong bones, with Avhich they have articulated, and by means of 

 which they have been connected with the spine, some other bones 

 perhaps intervening. Sir Everard Home describes the animal as 

 having a pelvis similar to that of the crocodile. 



Fig. 2, PI. XV, exhibits, on a larger scale, the imperfect remains of 

 a specimen from Saltwick, which has been about the same size, the 

 head being sixteen inches long, and having apparently lost about two 

 inches of its length. The head is compressed laterally ; but shews 

 part of the teeth, and gives an interesting view of the eye, where we 

 observe a circular bony plate inclosing a round cavity. If the bony 

 ring corresponds with the iris, or the sclerotic coat, and the central 

 cavity with the pupil, the eye must have been very large, the ring 

 being above three inches in diameter. It shews no marks of crystal- 

 lization, like what we see in some of Sir Everard Home's Figures. 

 In this specimen, there are portions of both the pectoral fins, with 

 some of the ribs, and a part of the spine. 



No. 3 is an interesting specimen belonging to Mr. Geo. Watson. 

 It was found between Whitby and Saltwick, in February 1819, within 

 ten yards of the cliff", and very near the dogger. The head is a yard 

 long, and has been some inches longer; and as we find in entire 

 specimens, that the head is about a sixth part of the whole length, the 

 animal when entire must have measured eighteen or twenty feet. The 

 upper jaw has been pressed down upon the lower, and twisted a 

 little to one side, displaying part of the inner surface of the lower jaw, 

 and shewing several of the teeth. The teeth are conical, and smooth, 

 or slightly ribbed; the cross fracture exhibiting concentric circles. 

 The beak is pressed into a portion of the spine, which meets it at 

 right angles : another fragment of the spine is found detached on the 

 same side near the neck ; but a much larger portion remains in its
