14 MR. G. A. BOULEXGER OX FISHES, BATRACHIAXS, [May C), 



broad ; snout rounded, strongly projecting beyond the mouth, with 

 scars of small horny warts ; eye perfectly lateral, in the middle of 

 the head, its diameter 4| times in the length of the head, 2| in the 

 width of the interorbital region, which is flat ; width of mouth, 

 with lips, I that of the head ; rostral flap and anterior boi-der of 

 lip not denticulated ; lower lip with a series of papillae forming a 

 denticulation ; inner surface of lip wdth numerous transverse 

 plicse, formed of closely-set obtuse papillae ; a minute barbel, 

 hidden in the folds at the side of the mouth. Dorsal II 10, with 

 strongly notched uppei- boixler ; the longest ray exceeds the length 

 of the head ; fin equally distant fi'om the nostiil and the root of 

 the caudal. Anal II 5, longest ray nearly as long as the head and 

 reaching the root of the caudal. Pectoral subfalciform, as long 

 as the head, not reaching the base of the ventral. Yential nearly 

 reaching the vent, its first ray falling under the seventh of the 

 dorsal. Caudal deeply forked. Caudal peduncle scai'cely longei- 

 than deep. Scales 36^1; 4 series between the lateral line and 

 the root of the ventral, 16 round the caudal peduncle. Olive- 

 brown above, whitish beneath ; fins dark. 



Total length 160 millim. 



A single specimen. 



Very closely allied to L. cylindricus Peters, fi'om the Zambesi, 

 but body strongly compressed, eye occupying the middle of the 

 head, and one scale moi'e in the transveise series above tlie 

 lateral line. 



2. Barbus trimaculatus Peters. 



3. Barbus rhodesiaxus, sp. n, (Plate II. fig. 2.) 



Depth of body 3| to 3| times in the total length, length of 

 head 4 to 4| times. Snout rounded, feebly projecting beyond 

 the mouth, g the length of the head ; diameter of the eye 3| to 

 4| times in the length of the head, 1| to 1| in the interocular 

 width ; mouth lather small, its width half that of the head, with 

 thin lips, with two pairs of subequal barbels measuring about 

 half the diameter of the eye. Dorsal III 8-9, third ray not at^ 

 all enlarged, smooth ; the fin, which is equally distant from the 

 eye and the root of the caudal, has the free edge notched and its 

 longest ray measures | to 4- the length of the head. Anal II 5 ; 

 the longest I'ay measures | to |^ the length of the head and 

 nearly reaches the root of the caudal when folded. Pectoral a 

 little shorter than the head, not reaching the ventral, the first 

 ray of which falls below the anterior third of the dorsal. Caudal 

 forked. Caudal peduncle about Ig as long as deep. Scales 

 30-32^5 2i or 3 between the lateral line and the root of the 



Of * 



ventral, 12 round the cavidal peduncle. Dark olive-brown above, 

 silvery below ; fins dark. 



Four specimens, measuring from 1 1 7 to 280 millim. 



Allied to B. mareqioensis Smith, B. altianalis Blgr., and B. 

 bowkeri Blgr. Difiers from all three in the shorter barbels and
