No. 2392. NEW DEEP-SEA FISHES FROM HAWAII— JORDAN. 645 



torals narrow, pointed, about as long as from tip of snout to front of 

 pupil. Dorsal fin very low, beginning well beyond tip of pectoral, 

 and in front of vent, as a mere fold of skin, growing higher on the 

 tail, where for a distance the height is almost equal to length of 

 eye; anal quite similar; tail ending in a filamentous point. Color 

 dusky, dotted with black, especially along the lateral line; the pec- 

 torals pale, the dorsal and anal slightly darker along the edge. 



Family MYCTOPHIDAE. 



NYCTIMASTER, new genus. 



Closely allied to Lampanyctus Bonaparte, having the same general 

 form, subacute snout, and elongate pectorals, but differing in not 

 having the scales of the lateral line enlarged. Lampanyctus croco- 

 dilus (Risso), the type of the genus, has these scales much larger 

 than the others, being deeper than long. Nannabrachium Giinther
