72 DR. GTJNTHER ON FISHES FROM KILIMA-NJARO. [Feb. 19, 



a broad fold pendent from tbe end of the snout. Eye of moderate 

 size, somewhat behind the middle of the length of the head, two 

 ninths of the length of the head, and nearly one half of the broad 

 and flat interorbital space. There are three longitudinal series of 

 scales between the lateral line and the root of the ventral fin. Bodv 

 rather elongate, its depth being equal to the length of the head and 

 two ninths of tlie total length, without caudal. The origin of the 

 dorsal fin is considerably in advance of that of the ventral ; in fact, 

 the fin occupies the middle of the distance between the end of the 

 snout and the root of the caudal. Pectorals inserted at the lower 

 side of the body, horizontal, but not reaching the ventral ; ventrals 

 long, broad, nine-rayed, extending beyond the vent ; caudal fin 

 deeply forked. Coloration uniform ; a small black spot on the 

 shoulders behind the upper end of the gill-opening. 



One specimen, 5 inches long. 



Unless one or tlie other of the Abyssinian fishes described by 

 Riippell as Barhus belongs to Tylognathus, this would seem to be 

 the first African species of this genus which hitherto has been known 

 to be represented in India and Syria. However, it should be remem- 

 bered that the separation of this genus from Laheo is artificial, and 

 maintained for other reasons (see Catal. Fish. vii. p. 02). Labeo is 

 well known to be a type common to both the African and Indian 

 regions. 



Barbtjs jacksoni, sp. nov. 



D. 10. A. 8. L. lat. 37. L. transv. 6/5. 



Two pairs of barbels, the posterior rather longer than the anterior 

 and about as long as the eye. Eye large, longer than the snout and 

 two sevenths of the length of the head. Interorbital space convex, 

 much wider than the orbit. The osseous dorsal ray is very strong 

 and smooth, longer than the head. There are three and a half 

 series of scales between the lateral line and the root of the ventral 

 fin. Body compressed, its height being two sevenths of the total 

 length, without caudal ; head small, two uinths of the same length. 

 The small mouth is anterior, the upper jaw but slightly overlapping 

 the lower, lips not thickened. The origin of the dorsal fin is oppo- 

 site to the root of the ventral, and but little nearer to the end of the 

 snout tlian to the root of the caudal ; caudal fin forked. Three 

 round black spots on the side of the body ; the two anterior above, 

 and ihe third on, the lateral line ; the first opposite to the seventli, 

 and the second opposite to the sixteenth scale of the lateral line. 



One specimen, 3| inches long.
