Family XLVIII. MUR^ENESOCID^E. 



Scaleless anguilloid eels, with the posterior nostril not labial, the 

 tongue largely adnate, the jaws not excessively elongate, the end of the 

 tail surrounded by the caudal fin, and the pectoral fins well developed. 

 None of these characters appear to have in themselves great importance, 

 but according to Dr. Gill, in the genus Murmnesox, the only genus in 

 which the osteology is well known, the characters are such as fully to 

 justify family distinction. Dr. Gill gives the following diagnosis of 

 Muraenesocidse : 



" Enchelycephalous Apodals with the tongue not free, the branchioste- 

 gal membrane connecting the opposite sides below, the epipharyngeals 

 reduced to one pair, and the hypopharyngeals linguiform and encroach- 

 ing on the fourth branchial arch." 



To this should be added: Gill openings rather wide; pectoral fins well 

 developed ; jaws of moderate length ; vomer well armed. 



Whether all these characters are found in the other genera commonly 

 associated with Mwcenesox is not yet known. The family, as understood 

 by us, seems divisible into two well-marked groups, which are, perhaps, 

 as distinct from each other as from the Echelidctt or the Congridw. The 

 species of this family are not very numerous, and a large proportion are 

 American. In general appearance and habits they approach the Con- 

 gers. All are plainly colored and some descend to rather deep water.

MURJENESOCIN2E: 



a. Dorsal and anal fins well developed throughout, the dorsal beginning nearly above gill 



opening; snout moderately produced; vomerine teeth very strong. 

 b. Teeth in jaws in several series ; gill openings wide.
