FOSSIL FISH. 403 



fins, which are veiy pointed and arched, that of the fins 

 which appear to be ventral, and perhaps the entire assemblage 

 of the parts, all led M. de Blainville to the belief that this 

 fossil belonged to Squalus, and to that species which he calls 

 innominatus, which has been confounded with carcharias, 

 and which is found in all the seas of warm climates, as well as 

 in the Mediterranean. 



Sq. glaums. This is after a much better preserved impres- 

 sion than the last, and in all probability the species is fossil at 

 Vestena Nuova. The teeth are visible, triangular, pointed, 

 scarcely denticulated, but notched or curved on the posterior 

 edge ; the form of the muzzle, pectoral fins, and tail, approxi- 

 mate this fossil to the Squalus glaucus, or some neighbouring 

 species, both inhabitants of the Mediterranean. 



Sq» catulus ? Volta. This impression is complete enough 

 to decide that it represents a species of the genus Squalus. 



Raia. Sp. Trygonobatus vulgaris? The body is evidently 

 round or oval; the pectoral fins are united anteriorly, and 

 there is no prolongation of the muzzle ; the pelvian or ventral 

 fins are entire ; the tail is very long and very slender, and fur- 

 nished with a denticulated point, or sting ; the teeth are very 

 small and graniform ; — so that it is not possible to doubt that 

 it is a sort of pastinaca, or trygonobatus. It is a mistake, 

 however, to regard it as analogous to the Sephen ray of For- 

 skael, which is totally different. The impression is very perfect, 

 and exists in the French Museum, 



Trygonobatus crassicaudatus, De Blain. The general form 

 of the body, the disposition of the pectoral fins in front, the 

 absence of all cephalic prolongation, the integrity of the ven- 

 tral fins, all -denote a fish of this subgenus. The tail, which 

 appears truncated, is remarkable for its great appearance of 

 strength, and its breadth at the base ; towards its posterior 

 extremity there is an indication of a sting. This fish was most 

 likely a native of the Mediterranean. 



Narkobatus giganteus, De Blain, This impression, though
