3®o Sir Everard Home's account of the 
texture, the fibrous appearance of the scapula, arising from a 
mode of growth only met with in the bones of fishes. 
The drawings annexed to this and to the former Paper, 
represent the principal bones composing the skeleton of this 
very extraordinary animal, and they correspond sufficiently 
with those of fishes, to remove all doubt of its having been a fish, 
but different from any fishes now in existence ; for although 
the pectoral fins bear a certain resemblance to those of the 
shark, there is none between many of the other parts, parti- 
cularly the long projecting snout and the conical teeth. 
In truth, on a due consideration of this skeleton, and of that 
represented in the 13th vol. of the An. Mus. p. 424, we cannot 
but be inclined to believe, that among the animals destroyed 
by the catastrophes of remote antiquity, there had been some 
at least that differ so intirely in their structure from any which 
now exist, as to make it impossible to arrange their fossil 
remains with any known class of animals. 
EXPLANATION OF THE PLATES, 
The drawings w r ere taken from specimens of bones in very 
different stages of growth, but undoubtedly belonging to the 
same species of animal.
