Differs from Ch. sloani only in that there are only 20 21 

 luminous organs between ventrals and anal. Length 250 mm. 

 Seems to us to be a doubtful species. 



Habitat: Flores sea (538 m.)!. Indie. 



3. Stomias Cuvier. 



(CuviER, Regne animal, II. 1817, p. 184). 



Elongate, strongly compressed, covered by very thin, deci- 

 duous, hexagonal scales. Head compressed, snout very short, 

 gape of mouth oblique and extremely wide, as also the gill- 

 opening. Lower jaw prominent, mandibles widely distensible. 

 Opercle narrow. Interopercle rudimentary. Chin with a fleshy 

 barbel, ending in three filaments. Pectorals and ventrals rather 

 narrow, the latter in the last */ 3 of the length. Origin of 

 dorsal above anal. No adipose fin. Ventral lobe of caudal 

 generally longer than the dorsal. Vent on a papilla just before 

 the anal. Teeth fixed, in maxilla numerous, small and approxi- 

 mate, those in the intermaxilla and mandible more or less 

 curved ; large and wide apart. Vomer with a pair of fangs, 

 palatines and tongue with smaller pointed teeth. Head with a 

 large suborbital photophore. Luminous organs between branchi- 

 ostegal rays. On each side a ventral series of luminous organs 

 from isthmus to caudal, above it a lateral series from gill- 

 opening to anus, besides numerous smaller organs scattered 

 between them. Four gills. No pseudobranchiae, nor gillrakers. 



We draw attention to the following figure (39) of a larva 

 of Stomias, from the Molucco-passage (1500 m.), distinguished 

 by its pellucidity, so that the myomeres can be counted, and 

 by the exceedingly long anal papil. It has D. 17; A. 21. 

 (see Siboga-Exp. Fische, p. 14).

Synopsis of the species. 



I. Intermaxillary teeth 4 6, longer than the mandibulary 

 teeth, which are few in number (about 8). 43 46 

 luminous organs between pectorals and ventrals S. valdiviae p. 112.
