Snout rounded, as long as the eye, which is contained 3^ to 4 times in length of head; interorbital width 2| to 2= times in length of head; mouth small, terminal; lips feebly developed, lower interrupted on the chin ; barbels two on each side, anterior | length of eye, posterior a little shorter than eye. Dorsal III 7, equally distant from eye and from root of caudal, with a straight or slightly convex border; last simple ray bony, strongly serrated, about % length of head. Anal III 5, longest ray f length of head. Pectoral .j to -J length of head, not reaching, or nearly reaching ventral; latter below anterior rays of dorsal. Caudal peduncle twice as long as deep. Scales 33-35 ~, 3 or 3| between lateral line and base of ventral, 12 or 14 round caudal peduncle. Brownish, with a more or less distinct dark streak along the middle of the side ; lateral line often blackish ; fins grey ; a blackish spot sometimes present at the base of the anal fin. Total length 55 millimetres. Numerous specimens from the Thika River, Tana system, 3000 ft. This species agrees very closely with the description and figure of B. gibbosus Peters*, which differs principally in having the caudal peduncle more than twice as long as deep. The name gibbosus being preoccupied (Cuvier and Valenciennes), I propose to designate Peters's Barbus from the Zambesi as B. longicauda. I also avail myself of this opportunity for changing the name Barbus miolepis, which I bestowed on a species from the White Nile in 1893, but which is preoccupied by a Congo species, to B. werneri, in honour of Dr. F. Werner, who has recently rediscovered the fish at Wady Haifa. 3. B arbus h ix d i i Blgr. Fort Hall, Kenya (Tana system), 4400 feet. Grows to a length of 390 millimetres. 4. B arbus perplexicans Blgr. Fort Hall and Thika River. Grows to a length of 350 millimetres. 5. A mphilius grandis, sp. n. (Plate VII. fig. 3.) Depth of body 5| to 6 times in total length, length of head 4 to 41 times. Head not or but slightly longer than broad ; eyes small, in the second half of the head, 2| or 3 diameters apart; intei-ocular width § or | length of snout; latter broadly rounded, projecting but slightly beyond lower jaw ; posterior nostril midway between eye and end of snout; prsemaxillary teeth forming a crescentic band, measuring ^ or 4 width of mouth; maxillary barbel measuring about f length of head, nearly reaching root of pectoral; outer mandibular barbel h length of head, inner Dorsal I 6, in the middle of the space between bases of pectorals * Reise 11.
