XXX VI.—On some new Genera and Species of Fishes collected by 
Drs. Keferstein and Heeckel at Messina. By Prof. Kaur. 
[With a Plate.] 
Family Leptocephalide, 
Genus STOMIASUNCULUS, n. g. 
Diagnosis. No ventral fins; distinct dorsal, caudal, and anal 
fins only towards the extremity of the body. Head large, with a 
lobe at the apex of the lower jaw. Operculum produced poste- 
riorly, with a large aperture directed far forwards. No teeth. 
Description. This is a very elongated form, round rather than 
compressed, with a smooth body, of which the muscular chevrons 
are very simple. Anus situated towards the extremity of the 
body, in a sacciform process. 
In this genus there is a certain resemblance to Stomias (such 
‘as occurs in Lsunculus to Esox), especially in the position of the 
dorsal and anal fins. I even suppose that the injured caudal fin 
was forked, as in Esuneulus, As there are still many gaps in 
this family, it is impossible to say exactly what is the true posi- 
tion of this genus. 
Stomiasunculus barbatus, Kaup. PI, III. fig, C, 
Head large, obtuse, with black eyes, not silvery as in the 
Leptocephali, The operculum and cheeks exhibit rows of fine 
points ; along the intestinal canal and the anal fin there is a 
row of points, such as occurs in many Leptocephali. The rays 
of the dorsal and anal fins are finely punctate; and there are 
also fine points on the lower part of the caudal. Found at 
Messina by Dr. Keferstein. The figure is three times the natural 
size. 
Genus LerrocerHauus, Gron. 
To this genus, which is far too little known, I add two new 
species, found at Messina and received from Drs, Keferstein 
and Heckel. . 
Leptocephalus Hackeli, Kaup, n.sp. PI. III. fig. B. 
Head small and pointed, with distinct teeth; no rows of 
points on the middle of the lateral line; rows of points along 
the yellowish intestinal canal; tail one-eighth of the length of 
the body. Resembles L. brevirostris, Kaup; but the snout is 
longer, the body not so high, and the tail less pointed. 
Leptocephalus Keferstemi, Kaup, n. sp. Pl. III. fig. A. 
Head extremely small, with very fine teeth. Seven roundish 
spots, composed of points, along the intestine. Anus rather be-
