convex, length J to 1 its width. Eye well advanced, hind profile 

 about first two-fifths in head length. Mouth cleft very short, wide. 

 Jaws with 5 conic teeth above in front and 6 below in front. Inter- 

 orbital convex. Scales with 9 or 10 basal radii. Each caudal lobe 

 scaly over basal two-tliirds and 12 scales around caudal peduncle. 

 Dorsal inserted little behind anal origin, slightly nearer caudal base 

 than pectoral origin; first branched ray, IJ to 2 in head; that of anal, 

 1| to 2. Caudal well forked, about IJ in head; pectoral, 1§ to If, 

 and ventral, 2i. Color in alcohol, brownish above to silvery-white 

 below. Fins ail pale. Iris grayish. Four examples, 98 to 116 mm. 

 Quanza River at Cunga. 



One of the above examples is distorted, having the lateral line and 

 apparently vertebral column in a somewhat sigmoid pattern. 



BARBUS EUTAENIA Boulenger. 



Head, 3f to 3J; depth, 2| to 3^; D. Ill, 8, once 7; A. in, 5; scales 

 23 to 25 in lateral line to caudal base and 2 more on latter, rarely 3; 5 

 scales above lateral line, 3 below, rarely 4; predorsal 9, rarely 10; 

 snout, 3 to 3| in head; eye, 3^ to 4; maxillary, 3f to 4; interorbital, 

 2f to 3. Body well compressed, back slightly elevated. Caudal 

 peduncle well compressed, least depth about I5 to If its length, or 

 If to If in head. Head width. If to If its width. Eye advanced, 

 hind pupil edge at least midway in head length. Mouth small, closed 

 lower jaw slightly included. Maxillary not quite to eye. Front 

 barbel slightly larger than eye and liind one longer, or equals eye 

 and space to hind nostril. Interorbital broadly convex. Rakers, 

 1+5 short points, about one-sixth of filaments, which IJ in eye. 

 Pseudobranchiae about one-third of gill-filaments. Teeth 2, 3, 5—5 

 3, 2, some of larger hooked and with well-developed grinding sur- 

 faces. Scales with 3 to 5 basal scallops, 5 or 6 distinct basal radii, 

 and about 4 or 5 apical radii. About 12 scales around caudal pedun- 

 cle. Caudal base covered with small scales for at least two-fifths of 

 lobe externally. Free axillary ventral scaly flap one-third of fin. 

 Scales on breast moderately small, about 9 across between pectoral 

 origins. Dorsal origin nearly an eye-diameter nearer snout tip than 

 caudal base, or about midway in half grown examples. Dorsal spine 

 with about 28 to 30 serrae along hind edge, variably little shorter 

 or longer than head. Upper dorsal edge a little emarginate. Anal 

 inserted little before depressed dorsal end or midway between ventral 

 origin and caudal base, nearer ventral in half grown. Caudal well 

 forked, usually an eye-diameter longer than head; pectoral, 1| to 

 It; ventral. If to 1|. 



Color in alcohol pale brownish generally, with bright or silvery 

 reflections, and lower surface paler. Side of head, iris, and broad
