 obtuse conical ; eye large, nearly half bead. Dorsal inserted nearly mid- 

 way between snout and root of caudal behind ventral ; pectoral nearly 

 reaching tip of ventral. Mediolateral spots 2 ; anterolaterals 2 ; jiostero- 

 laterals 2, over break in anal series ; anterolaterals far apart ; caudals 

 near together, the last far below end of lateral line ; a luminous plate on 

 caudal iieduncle ; anal spots 5 or 6 + 6 or 7. (Goode & Bean.) Mediter-

861. MICTOPHUM HYGOMIl (Liitken). 



Head 31; depth 4; eye about 2^. D. 12; A. 21 or 22; scales 38 to 

 42. Least height of tail about f of its greatest height. Snout very short, 

 the upper and lower profile of the head being similar, its length a little 

 less than I diameter of eye. Intermaxillary reaching as far back as max- 

 illary, nearly to angle of the preoperculum ; maxillary expanded pos- 

 teriorly and concealed under large scales of cheek. Space between eye 

 and hinder edge of preoperculum i- diameter of the eye. Origin of dorsal 

 nearer tip of snout than root of caudal, being over eleventh scale of 

 lateral line, and nearly over origin of ventral ; base of dorsal i as long 

 as head, length of longest ray equaling length of head without snout; 

 ventral not quite reaching vent ; pectoral as long as head, reaching 

 to above anal origin ; anal origin nearly under end of dorsal base, the 

 length of anal base a little greater than that of head; caudal rather 

 small and forked. Posterolaterals 2, over break in superanal series and 

 far apart, the anterior one nearly over middle of anal fin, the posterior one 

 about one scale in advance of the vertical from the root of the soft dorsal ; 

 anterolaterals widely separated, the first obliquely in advance of and 

 above the second, and touching or upon the lateral line, the second far 

 behind the root of the ventral and over the interval between the first 

 and second postventral photophores ; superanals 7+6. (Goode ».^' Bean, 

 as M. rcmiijer.) (Named for Captain V. Hygom, collector of some of Dr. 

 Liitken's "Spoils of the Atlantic") (Eu.)

BeiUhnsema, Goo»E & Bean, Oceanic Iclitliyciluiry, 7f'), 1895, {miilleri). 



This genus differs from Myctoplmvi in having the maxillary dilated at 

 tip. The dorsal fin considerably shorter than anal, but overlapping it, 

 reaching to the vertical from the middle, liody elongate; candal 

 peduncle somewhat stout ; eyes large ; snout very short, with declivous 

 upper profile; maxillaries considerably dilated behind; scales of the
