224 ON FISHES FROM EAST ANRICA. [June 17, 



and which has 8 oi" 9 branched rays to the dorsal fin and three 

 series of scales between the lateral line and the ventral fin. 



The Barhus described by Riippell from Lake Tsana, under the 

 names of Barhus intermedius, B. affinis, B. elongatios, and Labeo- 

 harhus nedgia, the type-specimens of which have been kindly 

 entrusted to me by the Directors of the Senckenberg Museum, 

 agree with the Tana species m the large scales and the very 

 strong fourth dorsal ray. All have 8 branched rays in the dorsal 

 fin and 3 series of scales between the lateral line and the ventral 

 fin.

7. Chiloglanis brevibarbis, sp. n. (Plate XYII. fig. 2.) 



Body slightly depressed, its depth 6 times in total length. 

 Head strongly depi-essed, 1^ as long as broad, its length 3 times 

 in total length. Eye directed upwards, in the second half of the 

 head, its diameter 5^ times in length of head and 1^ in interorbital 

 width ; anterior nostril equally distinct from the end of the snout 

 and the eye, posterior separated from the eye by a space equal to 

 the diameter of the latter ; prsemaxillary teeth wide apart, in two 

 large oval groups, forming 4 or 5 transverse series ; 6 rather strong 

 mandibular teeth ; maxillary barbel scarcely longer than the eye, 

 lower labials shorter than the eye. Dorsal I 5 ; spine not 

 serrated, half the length of the head. Adipose fin half as long as 

 its distance fi-om the rayed dorsal. Anal III 7. Pectoral spine 

 I the length of the head. Yentral extending to the oiigin of the 

 anal. Caudal forked. Caudal peduncle nearly twice as long as 

 deep. Pale bi-ownish above, with foiu- irregular dark ci'oss-bands 

 connected by a dai'k lateral stripe, whitish beneath ; two dark 

 bars across the anal ; a dark bar at the base of the caudal, another 

 across each lobe of the fin, and a dark streak along the lower lobe. 



Total length 55 millim. 



A single specimen. 



This species differs from C. deckeni Ptrs. and C. nilotictcs Blgr, 

 in the shorter barbels and the stronger mandibulai- teeth.
