Having purged the Berycidge of tlie forms wliicli liad been 

 unduly associated with them, I find that a family of that 

 name may still be defined by the number of soft rays in the 

 ventral Hn exceeding five, although I am not satisfied that 

 snch a group is a perfectly natural one, owing to the closer 

 affinity which appears to exist in other re.sjxcts between Beryx 

 and the Pempheridie than between it and the other genera 

 placed in the same family. Anyhow the group Bcryciformes, 

 as opposed to Perciformes and Scombriformcs, cannot be 

 maintained. The family may be thus diagnosed: — 



One or more of the suborbital bones with an internal 

 lamina sup])orting the globe of the eye; entopterygoid 

 present. Anterior vertebra; without transverse processes; all 

 or most of the ribs inserted on the transverse processes where 

 these are developed. Two nostrils on each side. Gill- 

 nienibranes free from isthmus ; gills four, a slit behind the 

 lourth ; pseudobianchia3 present. Lower pharyngeal bones 

 sepaiate. Ventral fins with one spine and six to thirteen 

 soft rays. 



l^elbre presenting, in synoptic form, the principal characters 

 of the thirteen genera into which the known living Berycids 

 may be divided, 1 wish to offer some remarks on the limits of 

 the genus TrachichtJnjs. 



This genus wa.s iuunded by Shaw on a .<5mall fish, T. aus- 

 trah's, in which the spines of tlic dorsal fiii are few in nuihber 

 (3), close together, and graduating towards the longer .soft
