2. Barbus tiiikensis, sp. n. (Plate YII. fig. 2.) 



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

 laagth. Snout rounded, as long as the eye, which is contained 3k 

 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 

 g length of eye, jDosterior 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 I length of head. Anal III 5, longest ray | length of head. 

 Pectoral | to f 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 |f, 3 or 3j between lateral 

 line and base of venti'al, 1 2 or 1 4 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 some- 

 times 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. (jibbosus Peters*, which differs principally in having the 

 caudal peduncle more than twice as long as deep. The name 

 gibbosus being preoccupied (Ouvier and Valenciennes), I propose to 

 designate Peters's Barbus fi-om the Zambesi as B. longicauda. 



I also avail myself of this opportunity for changing the name 

 Barbus miolejns, which I bestowed on a species from the White Nile 

 in 1893, but which is preoccujjied by a Congo a^ecies, to B. iverneri, 

 in Jionour of Dr. F. Werner, who has i-ecently rediscovered the 

 fishatWady Haifa. 



3. Barbus hindti Blgr. 



Fort Hall, Kenya (Tana sj'stem), 4400 feet. Crows toa leugtli 

 of 390 millimetres. 



4. Barbus pbrplexicans Blgr. 



Fort Hall and Thika River. Grows to a length of 350 



millimetres. 



5. Amphilius grandis, sp. n. (Plate YII. 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 bi-oad ; eyes small, 

 in the second half of the head, 2^ or 3 diametere apart ; inter- 

 ocular width I or i length of snout; latter broadly rounded, 

 projecting but slightly beyond loAver jaw ; posterior nostril midway 

 between eye and end of snout ; prasinaxillary teeth forming a 

 crescentic band, measuring ^ or |- width of mouth; maxillary
