Honoda nicgalofMhalma Diag'rami'.iatic ventral view of an- terior portion of botly, showing iiosition ot light organs. Bones and skin of head very fragile, nostrils not apparent ex- cept on one specimen, in which they appear to be placed high on snout as in other gonostomatid fishes. Pseudobranchiae small, found on only a few specimens, perhaps lost in others because of their fragility. Skin of abdomen thin, often damaged. A large, thin, cycloid scale present beneath pectoral of one speci- men from St. 1933, no scale pockets visible, extent of scalation unknown. Pin rays fragile, mostly liroken, probably normally all rather long, judging from renniants. Pectoral in some specimens reaching first or second anal ray. Ventrals, when complete, reaching anal origin. Photophores of BR, IV and OA series relatively large, the VA, and especially the AC, smaller. Total number of IV organs always 16, those of BR 6 except in one specimen, which has 6 on one side, 7 on the other. Number of VA and AC organs variable, the former 7 in twelve specimens, 8 in eight specimens and 7/8 in two specimens; t
