 lat. J^. 21° 15' 49", long. W. 157° 44' 27"). 

 Type.— "So. 47737, IJ^S.N.M. 



NEOSCOPELUS MACROLEPIDOTUS, Johnson. 



Nine specimens, 4 to Si inches long, from stations 3470 and 3474; 

 343 and 375 fathoms respectively. 



Taken heretofore at Madeira (Johnson) and Kermadec Islands (CIkiI- 

 lenger). 



Family MAUROLICID.E. 



ARGYRIPNUS, new genus. 



Body much compressed, oblong or elongate, passing gradually into 

 the slender tail, covered with very thin, tlexible, cycloid, deciduons 

 scales. Head longer than deep, without spines, its bones tliin and 

 llexible. Maxillary sickle-shaped, with spatulate supplemental bone. 

 Eye large. Dorsal fin on middle of back, without anterior spinous 

 dilatation. A large (double) luminous organ on preopercle and series of 

 equidistant organs on branchiostegals, isthmus, breast, abdomen, and 

 lower part of side. A continuous series from above base of ventral 

 fin to about the end of the anterior third of the base of the anal tin, 

 A closely set series of five si>ots above middle of anal fin. and another 

 series of fifteen beginning above hinder end of anal and extending to 

 the anterior rudimentary rays of the caudal. 



ARGYRIPNUS EPHIPPIATUS, new species. 

 (Plate XXXIX, tig. 2.) 



Head a little more than 3; depth 3,\. 1). 10 ; A. 22; P. 15. 



Body strongly compressed, its width 2'-^ in the greatest depth. Dor- 

 sal and ventral outlines nearly similar, but the former descends more 

 rapidly under the dorsal fin than elsewhere and the latter ascends a 

 short distance very abruptly behind the base of ventral fins. Depth 

 of body at the nape and at origin of dorsal fin equal; least depth of 

 l)eduncle 3 in greatest depth of body. Head compressed, its greatest 

 width (behind the orbit) 2 in its greatest depth; its dorsal and ventral 

 l)rofiles similar, stongiy curved. Orbit large, 2| in head, circular, its 

 upper margin entering profile. Interorbital space (somewhat crnslu'd 

 in the single specimen) about 5i in head. Snout broad, short, about 2 

 in orbit, its ti[) on a level with center of eye. Mouth wide, very <)bli(iu(» 

 anteriorly. IMemaxillary slender, nearly as long as orbit, forming an 

 angle of about 45"^ with axis of body, its lower end reaching about to 

 the vertical from anterior margin of orbit. Maxillary reaching very 

 nearly to i)osterior margin of orbit, somewhat sickle-sliaped, with a 

 rather sharp curve opposite the lower end of the premaxillary, and 

 slightly overlapped at its posterior end by its spatulate supplemental
