Gymnotm. Mr. Gill names now the Electric Eels Electt'ophorus, retaining 
the name of Gymnotm for Carapus. Proc. Acad. Nat. Sc. Philad. 1864, 
p. 161. 
Leptocephali. 
In anticipation of a more extended memoir, Mr. Gill expresses 
his unqualified belief in the opinion that these fish are simply 
larval forms. He is almost certain that the typical Leptoce- 
phali, at least, are the young of Congers, and that L. morrisn is 
the young of Conger vulgaris. Hyoproprus messinensis (Kbll.) 
appears to be the larval form of Nettastoma melanura. Sto- 
miasunculus resembles, in general features, a larval Clupeoid, 
abbut three days old, in which the ventral fins have not yet ap- 
peared. Esunculus is likewise a larva, and Forobronchus (Kaup) 
is, perhaps, related to Fierasfer, Proc. Acad. Nat. Sc. Philad.
