In an appendix to this family the author treats of the Leptocephaiidee.
He distinguishes between really Leptocephaline forms
and such as have been very improperly referred to the same
group. He is inclined to regard the former as the offspring
of Muraenoids, but as individuals arrested in their development
at a very early period of their life, yet continuing to grow to a
certain size without corresponding development of their external
organs, and perishing without having attained the characters of
the perfect animal. To this form belong all the various Leptocephali
and Hyoprorus. Tilurus is a similar form arrested in its
development, but cannot be the offspring of a Mursenoid fish.
Stomiasunculus (Kaup) is the young of Stomias, Porobronchus
(Kaup) the young of Fierasfer acus, and Esunculus (Kaup) probably
that of Alepocephalus.

PEGASIDJE.
These fishes are not Lophobranchs; they resemble, in several
points, even the Acanthopterygians; and Prof. Steenstrup places
them with the Cataphracti. Gunther, Fish. viii. p. 146.
