deep and least depth 2^ to 2^ in head. Head width, If its length. 

 Snout broad, length lialf its width. Eye advanced; hind edge 

 slightly before center in head length. Month broad. Teeth ex- 

 tremely minute, rudimentary, few, in single row and only in upper 

 jaw. Maxillary concealed, not quite to eye. Upper lip width nearly 

 half of pupil. Nostrils close: front one about midway in snout. 

 Interorbital broadly convex. Preorbital denticulate. Rakers, about 

 40 + 51, finely lanceolate, about half of filaments and latter equal eye. 

 Scales with 7 to 9 basal striae. Cheek with 3 rows of scales. Pectoral 

 without axillary scaly flap, and 4 scales behind depressed spinous 

 dorsal tip and soft dorsal origin. Spinous dorsal inserted midway 

 between eye center and caudal base, or midway between front eye 

 edge and caudal base in small examples: second spine slightly longer, 

 or 1| to 2^ in head. Soft dorsal inserted mu(;h nearer spinous dorsal 

 origin than caudal base, first branciied ray, Hii^ head. Anal inserted 

 about midway between ventral origin and caudal base, If to If in 

 head. Caudal large, pupil length in smallest example to eye-diameter 

 longer than head in larger ones: pectoral, l\: ventral, 1^. Color in 

 alcohol, dull olive-brown above: sides and below, paler Avith silvery- 

 white reflections. Iris whitish. Fins all pale brownish, with obso- 

 lete brownish blotch at pectoral base. Eight examples, 105 U> 

 145 mm. 



Boulenger's figure ^ does not indicate any scales on the opercle; 

 those on the cheek imperfect and front of soft dorsal and anal basally 

 scaleless. In all my examples these areas are quite scal3\ 



An Angola example in the Academy (Bengo River at Cabu'i) 

 shows: head, 3f; depth, 3f: D. IV— I, 9; A. Ill, 11; scales, 39 

 from shoulder to caudal base and 6 more on latter; transverse scales, 

 13; predorsal, 23; snout, 4 in head; eye, 3§; maxillary, 4; inter- 

 orbital 2f ; few scales on front of anal basally; length, 82 mm.

Head, 3f; depth, 4f; D. IV— I, 8; A. Ill, 9; scales, 36 from 

 shoulder to caudal base and 5 more on latter; 13 scales transversely 

 between soft dorsal and anal oiigins; 25 predorsal (pockets) scales; 

 snout, 4f in head; eye, 3f ; maxillary, 4; interorbital, 3. Elongate, 

 rather slender, or deepest at spinous dorsal origin, well compressed. 

 Caudal peduncle with least depth. If its length, or 2^ in head. Head 

 width half its length. Snout length nearly tin ee-fif ths its width. 

 Eye advanced; hind edge about midway in head length. Mouth 

 broad; would form obtuse angle. Row of minute ciliate teeth in 

 upper jaw. Maxillary exposed, almost to eye. Nostrils close to- 

 gether, front one about midway in snout length. Interorbital 

 broadly convex. Preorbital denticulate. Rakers, 35+46, about
