bone. Lower jaw entirely included laterally, and concealed by the over- 

 hanging- maxillary, curved upward anteriorly, its tip entering profile. 

 Teeth on premaxillary, maxillary, mandible, and ])al;itines, few, in 

 single series, sharp and slender; a tooth on each premaxillary about 

 midway of its length, the anterior tooth of the palatine series and one 

 or more at the side of the lower jaw longer than the rest. Tongue 

 broad, free in front. Preopercular edge nearly vertical, (lill mem- 

 branes not united. Psendobranclii;e large. Gill rakers long, 2.i in 

 orbit, 15 on anterior limb of first arch. I>oues very thin and flexible, 

 the usual deep-sea characters prominently develoi)ed. Scales large, 

 very thin and flexible, cycloid, highly deciduous, nearly all lost in the 

 type specimen, which is here figured as it appears, scaleless with con- 

 spicuous muscular impressions. 



FltospJiorcscenf organs. — Two on opercle below the level of the orbit, one 

 above the other, at the two ends of a short vertical steel-blue band from 

 which they are separated by small black cross bauds; one on cheek 

 immediately behind tip of maxillary ; 5 oblong (vertical) spotson branch- 

 iostegal membranes; a curved row of 6 nearly circular s])ots from base 

 of pectoral to anterior end of isthmus; a nearly straight row of 10, 

 equidistant, circular and smaller, on each side of middle line, beginning 

 at humeral symphysis and running along abdomen to front of base of 

 ventrals; a series of 7 oblong, vertical organs, yellowish at the lower 

 and pearl-colored at the upper end, farther up on the side, on a level 

 with the i)ectoral fin; immediately behind this, over tiie root of the 

 ventral tin, begins a series of 10 organs which gradually become smaller 

 posteriorly, and runs geutly dorsalward to origin of anal, then rises a 

 little higher with an abrupt curve and continues horizontally to abont 

 the end of the anterior third of base of anal; behind this a series of 5 

 small organs above the middle of anal; a series of 15 very small organs 

 begins just in front of the end of the anal and extends along its base 

 and close to the mid- ventral line of the caudal peduncle to the root of the 

 anterior caudal rudiments; probably one in front of and one behind 

 the orbit (injured.) 



Distance from tip of snout to origin of dorsal 2;^ in length of body, 

 from tip of snout to root of ventrals -54, to origin of anal 1^, length of 

 base of dorsal 7, base of anal 3^ in length of body. Vent midway 

 between root of ventrals and origin of anal. Pectoral fin very low, the 

 lower end of its base nearly entering ventral profile, narrow, its longest 

 rays reaching the vent, -l in length of body. Eays of all other fins 

 badly injured; anterior rays of anal much stronger than the posterior. 

 Origin of anal a little in front of end of first dorsal. 



Color {in alcohol). — Snout and most of jaws yellowish white; poste- 

 rior part of interorbital space, occii)ut, and back nearly to dorsal fin, 

 upper three-fourths of eyeball, sides of head behind orbit, isthmus, 

 breast, abdomen, areas occupied by the phosi)horescent organs, gill and 

 mouth cavities, black. Small black dots at the base of the rays of the
