of it which remain exhibit the upper portion of the head from 

 the nostrils backwards, in a very crushed state, a continuous series 

 of 52 vertebrae, from the atlas to the commencement of the tail, 

 with nearly all the spinous processes ; one scapula, and nearly the 

 whole of one fore paddle. The teeth (by which the four species 

 formerly described have been chiefly distinguished) are entirely 

 wanting in this individual; the author, however, considers it to be a 

 new species, from the following peculiarities of character. 



1. The length of each vertebra is uniformly three-fifths of its 

 breadth, a proportion not found to exist in any hitherto described 

 species. 



2. The paddle is of great size, and including the humerus must 

 have been equal to one-fifth of the length of the whole animal. 

 In the ulna or radius (it is difficult to say which) there is a notch 

 on the outer edge, and all the other bones of the paddle are very 

 nearly circular or oval ; thus differing essentially from the angular- 

 shaped phalanges of I. communis, tenuirostris, and intermedius. 



On account of the large size of its paddle, the author names this 

 species " Ichthyosaurus grandipes."
