to tip of snout ; maxillary and premaxillary closely welded, their separa- 

 tion marked by a changing in the character of the teeth, those on the 

 maxillary being minute cirri. The large fangs in the tip of the mandible \ 

 length of upper jaw; hyoid barbel placed at a distance from the sym- 

 physis of the mandible, which Is about equal to the enlarged fangs of the 

 mandible, or J- length of mandible ; length of the barbel nearly \ of total ; 

 pectoral close behind the head and near ventral outline, its first ray dis- 

 tinct from the other three, although placed close to them, and not pro- 

 duced ; length of the pectoral 4 in head ; ventrals in advance of middle 

 of body, their distance from origin of pectorals i as great as from caudal 

 base, their longest ray nearly equal to greatest height of body ; distance 

 of dorsal origin from caudal base 5 in total length ; longest dorsal ray 

 in middle of fin, half as long as longest of ventral; base of anal slightly 

 longer than that of dorsal, its longest ray about f as long as the longest 

 dorsal ray; caudal lobes in type unequal, the lower one being much 

 longer than the upper (perhaps result of accident.) Two rows of lumi- 

 nous spots, one close to the ventral outline, which becomes obsolete 

 before it reaches the origin of the anal, and another in the lower third 

 of height of body, which becomes indistinct about the middle of total 

 length ; 14 of these spots between pectoral and ventral in the lower 

 series and 11 in upper series. One specimen, 6| inches long, taken by the 

 Albatross at station 2565, N. latitude 38 19' 20", W. longitude 69 02' 

 30", from 2069 fathoms. (Goode & Bean.) (dentatus, toothed.)

Body compressed, rather long, scaleless ; vent far behind the middle of 

 the length. Head compressed, with short snout and exceedingly wide 

 mouth. Teeth in the jaws small, unequal in size, in single series; vomer 

 and palatine with a small group of teeth on each side. Eye small. 

 Opercular portion of the head very narrow. A long hyoid barbel. The 

 dorsal fin opposite the anal, which commences behind the vent ; pec- 

 torals none; ventrals inserted behind the middle of the length. A 

 small suborbital phosphorescent organ, and 2 series of luminous dots 

 along the lower part of the sides, with numerous rudimentary similar 

 organs scattered over the skin of the body. (0wf, light; vrjurr}^, 

 swimmer.) 



887. PHOTONECTES GRACILIS, Goodo & Bean. 



Head 8i ; depth 15 ; eye 4. D. 18 ; A. 21 ; V. 7. Much more slender 

 than the Japanese species, P. albipinnis. Type in very poor condition. 

 Hyoid barbel remarkably short and probably imperfect. Fins incomplete, 

 and the luminous dots along the sides so indistinct as to be made out 

 only with great difficulty. The greatest depth of the head equal to length 

 of its postorbital portion; snout very short, nearly half eye. Below and
