POROMITRA, new genus.

A single individual, 1| 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 satisfactory 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 Berycidte, 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 elsewhere. 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 bodv, its origin not far behind that of the %/ * "7 ventrals, the spinous and soft portions subequal in length. Anal much shorter than dorsal, its middle under the end of the dorsal, or nearly so. Pseudobranchiae present. Gill openings very wide, separate.
