72 DR. GUNTHER ON FISHES FROM KILIMA-NJARO. [Feb. 19, 
a broad fold pendent from the 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. Body 
rather elongate, its depth being equal to the length of the head and 
two ninths of the 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 the other of the Abyssinian fishes described by 
Riippell as Barbus 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 Ladeo is artificial, and 
maintained for other reasons (see Catal. Fish. vii. p. 62). Labeo is 
well known to be a type common to both the African and Indian 
regions. 
BARBUS 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 ninths 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 than to the root of the caudal; caudal fin forked. Three 
round black spots on the side of the body ; the two anterior above, 
and the third on, the lateral line ; the first opposite to the seventh, 
and the second opposite to the sixteenth scale of the lateral line. 
One specimen, 32? inches long.
