A single young individual, apparently of this species (D. VIII, i, 27 ; A. II, 

 i, 24 ; V. I, 5 ; L. lat. ca. 39), was taken at Station 324 ; its length is 33 mm. 

 In all probability the fish-was caught near the surface, while the trawl was on 

 its way up, and not on the bottom. 



BERYCID^. 

 POROMITRA, new genus. 



A single individual, 1 j inches long, was obtained at Station 328, and another 

 one of about the same length is in the collection without locality. The species 

 comes to us in such a dilapidated condition, that it is impossible to make a sat- 

 isfactory diagnosis of its characters. It seems to differ widely from anything 

 heretofore described. As it is, we simply describe it under a new generic 

 name, and at present shall refer it to Berycidxc, to which, as we now view it, it 

 appears to be related. 



Provisional Diagnosis. — Body short, compressed, scopeliform, covered with 

 thin cycloid scales. Head very large, nearly half the entire length of the fish 

 to base of caudal, with scales upon cheeks, suboperculum, and probably else- 

 where. No barbel. Mouth very large, the lower jaw projecting. Margin of 

 upper jaw composed of a short intermaxillary and a long maxillary. Teeth 

 cardiform, numerous, very small, on the intermaxillaries and mandibles. None 

 discovered on maxillaries, palatines, or vomer. Opercular apparatus complete. 



Dorsal fin in the middle of the body, its origin not far behind that of the 

 ventrals, the spinous and soft portions subeqnal in length. Anal much shorter 

 than dorsal, its middle under the end of the dorsal, or nearly so. Pseudo- 

 branchiae present. Gill openings very wide, separate.
