Apodal Fishes of Bengal. 225 



amount of species now existing throughout the whole of 

 Europe. Yet in a single locality of that temperate conti- 

 nent, nine fossil species of Anguillahave already been found. 

 These are imbedded in the slaty rocks of Monte Bolca, 

 together with a species of Ophisurus, sl genus now nearly 

 restricted to the tropics alone, and which is almost as little 

 known in Europe in the present day, as the Crocodiles and 

 Tapirs with whose bones its remains are mingled in Italy 

 and France. 



NOTE. 



Should it be thought necessary to separate the Bengal species of the genus from 

 Anguilla, Cuv. on account of their naked tessellated scales, I would propose the 

 following name and characters for the new group. 



Sub-genus. — Terpolepis.— Lower jaw broader, and longer than the upper. 

 Dorsal and anal as in the genus Anguilla, body covered with minute naked oblong 

 tessellated scales. Teeth conical, small, slightly hooked, and disposed in abroad band 

 on either side of the jaws, as well as on the vomer. Anterior nostrils tubular. 



ERRATA. 



With respect to the genus Cossyphus, p. 403 vol. IV. I find that name has 

 been previously appropriated to another genus by M. Valenciennes, I there- 

 fore propose Phagorus, the Greek name of an unknown kind of fish, to be substi- 

 tuted for the genus in question, in place of the first mentioned name.
