width, 2f to 2^; interorbital, 2 to 2J; eye, 4^ to 5| in interorbital. 

 Body compressed, deepest at dorsal origin. Head width, 1^ to 1| 

 its length, coarsely granular above, more so in half-grown. Snout 

 wide, depressed; length about two-fifths to one-half its width. Eye 

 small, at first third in head, or hind edge at first third in half-grown. 

 Mouth broad, with fleshy papillose lips; under jaw shorter. Broad 

 bands of villiform teeth in jaws and on vomer; band of upper jaw 

 about three-fourths width of vomerine band. Nasal barbel about 

 three-fifths to gill-opening; maxillary to middle of pectoral spine 

 or four-fifths in half-grown; outer mental to pectoral origm and 

 inner about two-thirds in head length. Width of long frontal, one- 

 fourth its length; one-third in half-grown or 3i to 3^ times occipital 

 fontanel. Occipital process triangular; length about two-thirds 

 its base. Rakers about 15 + 76; lanceolate, fine, slightly longer 

 than filaments or equal eye. Space between dorsal and caudal 

 1^ to If eye-diameters. Dorsal begins slightly behind middle in 

 space between pectoral and ventral origins in half-grown to last 

 two-fifths in adults. Anal origin midway between hind fontanel 

 edge and cUudal base in half-grown or about midway between snout 

 tip and last dorsal ray base in adult. Caudal, If in head; pectoral, 

 If to 1|; ventral, 2 to 2f. Outer pectoral spine edge serrate, obso- 

 lete with age. Color in alcohol dull brownish, paler below. Seven 

 examples, 303 to 406 mm., from the Quanza River at Cunga.

Head, 4|; depth, 5; D. I, 6; A. ii, 52; P. I, 10; V. i, 5; head 

 width, 1^ its letigth; dorsal spine. If; pectoral, 1^; ventral, 2^^; 

 snout, 3 in head, measured from upper jaw tip; eye, 4J; mouth 

 width, 2; interorbital, 2. 



Body elongate, rather slender, well compressed, deepest at spinous 

 dorsal origin; predorsal trenchant and breast broad. Caudal pedun- 

 cle strongly compressed, about long as deep, and least depth about 

 3| in total head length. 



Head broader below, converges above, and profiOles alike. Snout 

 broad; front edge but little convex as seen from above, and length 

 in profile about two-fifths its width. Eye lateral, though equally 

 visible above and below; upper edge level with closed tip of lower 

 jaw, and hind edge slightly advanced before middle in head length. 

 Mouth wide, lower jaw slightly protruding, and rami low. Teeth 

 villiform, in broad bands in jaws and across vomer and palatines; 

 latter continuous band slightly widens backward on each palatine. 

 Tongue broad, thick, free around front edge. Barbels fine; long 

 nasal reaching back behind eye or about If in head; maxillary about 

 half an eye-diameter beyond head; outer mental about an eye- 

 diameter beyond eye, and inner mental about two-fifths length of
