than eye. Barbel nearly as long as head. Origin of dorsal a 

 little behind origin of anal, which is higher than dorsal. Ventrals 

 prolonged, reaching on anal. Pectorals near ventral profile, 

 equal to height of body. About 25 unequal and curved teeth 

 in each intermaxilla, the first and fifth the largest, but smaller 

 than the large of the circa 13 teeth in each mandible; those 

 on the maxilla about 30, minute, close-set, directed backward. 

 Suborbital organ very small. 16 17 luminous organs between 

 branchiostegal rays. The ventral series of luminous organs be- 

 tween isthmus and pectorals consists of 6, between pectorals 

 and ventrals of 34 38, from ventral to anal of 6, from anal to 

 caudal of 16 17 organs. Uniform black with metallic gloss. 

 Fins and barbel white, the last with black tip. Length 135 mm. 

 Habitat: Flores sea (521 M.)!; Timor sea (421 M.)!; 

 Manipa-straits (1536 M.)!. - - Indik (Gulf of Manaar 1093 M.) ; 

 East coast of Africa 693 1119 M. 



4. Melanostomias Brauer. 



(BRAUER, Zool. Anzeiger XXV. 1902, p. 284). 



Elongate, strongly compressed, tapering posteriorly, scaleless. 

 Gape of mouth extensive as also the gillopening. Opercle little 

 developed. Chin with a well developed barbel. Pectorals short, 

 ventrals long, far behind middle of body. Dorsal opposite to 

 anal and shorter than that fin. No adipose fin. Caudal short, 

 forked. Vent near anal. Intermaxilla and mandible with large 

 bicuspid depressible teeth. Maxilla anteriorly with some large 

 teeth, posteriorly with numerous small ones, directed back- 

 ward. Teeth on vomer and palatines, and sometimes on tongue. 

 Behind the eye is a large revolving postorbital luminous organ, 

 an inconspicuous organ below the eye and one on the opercle. 

 12 organs between the branchiostegal rays, besides numerous 

 small ones round the eye, on the jaws and scattered on the 

 head. On each side a ventral series of organs beginning behind 

 the isthmus and running to the caudal, a lateral series from 

 gillopening to anal. Numerous small organs and whitish puncti- 

 form ones in groups ventrally of each larger organ of a 

 longitudinal series, and in transverse rows on the body. 4 gills. 

 No pseudobranchiae. n 12 branchiostegals. [after Brauer].
