Show 24 MR. G. A. BOULENGER ON [Jan. 20, Two specimens from near Efulen. This new species, allied to L. parvus Blgr., is interesting as completely connecting Labeo with Tylognathus, and showing that the latter genus can no longer be distinguished. 13. B a r b u s p r o g e n y s , sp. n. (Plate III. fig. 1.) Depth of body 3| times in total length, length of head 3^ times. Snout rounded, depressed, 3| times in length of head ; eye supero-lateral, its diameter equal to the interorbital width and 5 times in length of head ; mouth large, its width 3J 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 J diameter of eye, posterior as long as eye, the distance between them § diameter of eye. Dorsal III 10, last simple ray feeble, not stronger than those following, j| length of head; free edge of the fin emarginate; its distance from the occiput less than its distance from the caudal. Anal II 5, longest ray \ length of head. Pectoral J length of head, not reaching ventral; latter slightly posterior to origin of dorsal. Caudal peduncle 1| as long as deep. Scales 33 , 2 j 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. boivkeri Blgr., from Natal. Distinguished by the more anterior dorsal fin with 10 branched rays, the shorter anal fin, the narrower interorbital region. 14. B a r b u s t ^e n iu r u s , sp. n. (Plate II. fig. 2.) Depth of body 3| to 3| times in total length, length of head to 4 times. Snout rounded, 3| to 4 times in length of head; diameter of eye 4 times in length of head, interorbital width 2^ to 2| times ; mouth inferior, its width 3 to 3| times in length of head; lips moderately developed, interrupted on the chin; barbels two on each side, anterior 1|, posterior 1| to 2 diameters of eye, the distance between them equal to diameter of eye. Dorsal III 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 f to | length of head. Pectoral -J to ^ length of head, not reaching ventral; latter a little posterior to origin of dorsal. Caudal peduncle 1| as long as deep. Scales 24-27 2| 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 wThite. |
