24 MR. G, A. BOULENGER ON [Jan. 20, 
Two specimens from near Efulen. 
This new species, allied to LZ. parvus Blgr., is interesting as 
completely connecting Labeo with Tylognathus, and showing that 
the latter genus can no longer be distinguished. 
13, BARBUS PROGENYS, sp. n. (Plate III. fig. 1.) 
Depth of body 33 times in total length, length of head 
32 times. Snout rounded, depressed, 33 times in length of 
head ; eye supero-lateral, its diameter equal to the inter- 
orbital width and 5 times in length of head; mouth large, its 
width 32 times in length of head, lower jaw projecting beyond 
the upper; lips well-developed, lower interrupted on the chin ; 
barbels two on each side, anterior # diameter of eye, posterior as 
long as eye, the distance between them $ diameter of eye. Dorsal 
TIT 10, last simple ray feeble, not stronger than those following, 
2 length of head; free edge of the fin emarginate; its distance 
from the occiput less than its distance from the caudal. Anal IT 5, 
longest ray 4 length of head. Pectoral 3 length of head, not 
reaching ventral; latter slightly posterior to origin of dorsal. 
Caudal peduncle 1% as long as deep. Scales 33 2, 23 between 
lateral line and ventral, 12 round caudal peduncle. Silvery, 
brownish on the back, dorsal and lateral scales brown at the base ; 
dorsal and anal edged with blackish, the former with an ill-defined 
dark band across the middle; other fins whitish. 
Total length 180 millim. 
A single specimen from the Kribi River. 
Allied to B. bowkeri Blgr., from Natal. Distinguished by the 
more anterior dorsal fin with 10 branched rays, the shorter anal 
fin, the narrower interorbital region. 
14, BARBUS TENIURUS, sp. n. (Plate IT. fig. 2.) 
Depth of body 33 to 34 times in total length, length of head 
23 to 4 times. Snout rounded, 34 to 4 times in length of 
head; diameter of eye 4 times in length of head, interorbital 
width 21 to 24 times; mouth inferior, its width 3 to 33 times 
in length of head; lips moderately developed, interrupted on 
the chin; barbels two on each side, anterior 14, posterior 14 
to 2 diameters of eye, the distance between them equal to diameter 
of eye. Dorsal IIT 8, last simple ray ossified and moderately 
strong, but much thicker than the first branched ray, a little 
shorter than head; free edge of the fin emarginate; its distance 
from the occiput much less than its distance from the caudal. 
Anal III 5, longest ray 2 to # length of head. Pectoral # to 4 
length of head, not reaching ventral; latter a little posterior to 
origin of dorsal. Caudal peduncle 13 as long as deep. Scales 
24-27 aoe 23 between lateral line and ventral, 12 round caudal 
peduncle. Olive-brown above, yellow on the sides and below; a 
series of black dots on the lateral line, and a black band on each 
side of the caudal peduncle; fins white.
