FOSSIL FISH. 407 



more perfect. It is still, however, more than probable that it 

 is no Pegasus ; nor is there any genus in which it can be 

 placed without difficulty. 



LoPHius. Loph. piscatoriusy var. There can be no doubt 

 of the identity of this ichthyolite with the frog-fish ; but as it is 

 extremely small, it may perhaps be the variety called ganelli 

 by M. Risso, which is always smaller than the common Loph. 

 piscatorius, and which is very common in the Mediterranean. 



FisTULARiA. F, Bolcensis. This impression is very common 

 at Vestena Nuova, may be about half a foot in length, and 

 seems really to belong to this genus. A very small vertical 

 mouth is visible, at the end of a very long and very broad 

 muzzle ; the pectoral fins are scarcely to be distinguished, and 

 the ventral not at all ; but at the extremity of the body, above, 

 there exists a single dorsal fin, very low and very short, 

 opposed to an anal, of the same form. M. Volta supposes 

 that this fossil is analogous to the Fistularia chinensis ; but it 

 is evident, even in the state in which it is seen, that there are 

 numerous differences, in the proportion of the muzzle, in the 

 total absence of stings in front of the dorsal fin, in the separa- 

 tion of the dorsal and anal fins, and in the general form. 



F. dubia, De Blain. A species very probably of the same 

 genus, but far too incomplete to give any assurance of its 

 identity. It is represented in the Veronese work, under the 

 name of Fistularia petunha; the head, however, proportion- 

 ally larger than in the preceding species, seems to forbid this 

 approximation. 



Esox. E. longirostris, De Blain. An incomplete fossil, 

 referred by Volta to E. Bellone, but its identity with which is 

 more than doubtful. Its muzzle is proportionally longer, and 

 seems widened towards the extremity, which is certainly not 

 the case with Bellone. , 



-E. syphrcena, A very fine impression, about a foot in length, 

 and, to all appearance, perfectly analogous with the Sphyreena
