from the Quanta and Bengo Rivers. 551 



across chin ; two barbels on each side, anterior a little 

 shorter than posterior, which measures 1 to If diameters of 

 eye. Dorsal III 8-9, equally distant from anterior border 

 or centre of eye and from caudal, border concave, last 

 simple ray very strong, bony, not serrated, as long as or a 

 little shorter than head. Anal III 5, not reaching caudal. 

 Pectoral a little shorter than head, not reaching ventral ; 

 base of latter below anterior soft rays of dorsal. Caudal 

 peduncle lg- to 2 times as long as deep. Scales finely 

 striated longitudinally, 29-31 g, 2-2^ between lateral line 

 and ventral, 12 round caudal peduncle. Brownish above, 

 silvery white beneath, the scales on the upper parts blackish 

 at the base ; fins greyish. 



Three specimens, measuring 110 to 150 mm., from the 

 Quanza River at Dondo. 



This species, named after Dr. William J. Ansorge, is 

 distinguished from the preceding by the more slender body, 

 the longer caudal peduncle, the more pointed snout, and the 

 narrower mouth. 



Native name : Quangalatunda. 



22. Barbus girardi, sp. n. 



Depth of body 3 to 3^ times in total length, length of head 

 3^ to 4g times. Snout rounded, 3§- to 3i times in length of 

 head ; eye 3 (young) to 4 times in length of head, inter- 

 orbitakwidth 2i to 2| times ; mouth inferior, its width 3^ 

 to 4 times in length of head ; lips rather feebly developed, 

 lower restricted to the sides ; two barbels on each side, 

 subequal, or posterior a little longer, 1| to 1^ diameters of 

 eye. Dorsal IV 10, equally distant from anterior or pos- 

 terior border of eye and from caudal, border concave, last 

 simple ray very strong, bony, not serrated, 1 to 1^ times length 

 of head. Anal III 5, reaching caudal in the adult. Pectoral 

 as long as head, nearly reaching ventral ; latter below 

 anterior soft rays of dorsal. Caudal peduncle 1| times as 

 long as deep. Scales finely striated longitudinally, 40-44 

 gp^f, 3^-4^ between lateral line and ventral, 16-18 round 

 caudal peduncle. Brownish above, the scales darker at the 

 base, whitish beneath ; all the fins of a rich red in life. 



11 specimens, measuring from 60 to 300 mm., from the 

 Lucalla River at Lucalla. 



This species, named after Dr. Albert Girard, Director of 

 the Lisbon Museum, is allied to B. inter'medius, Riipp., but 

 distinguished by smaller scales.
