KONNUERG, FISHK.S. 5 



Uiirldis liinilii BOULKNOEH. 

 Barbux Hindi! BOULENGER Proc. Zool. Soc. 1902 p. 222. 



3 specimens from the river Sanya, which unfortunately have been spoiled agree 



as far as can be judged from general proportions, number of rays of dorsal and anal 



tins etc. with this species. 1 The fourth dorsal spine is, however, not quite so long as 



(lie head and the barbels appear to be even shorter than in the fish from Mount Ken3^a, 



'thus still smaller than in its ally B. tanensis GUNTHER. 



This fish was seen in small schools swimming near the bottom. It was caught on 

 hooks baited with dragonflies. 



Harbus usaiubani' n. sp. 



1 specimen from a pool on inundated ground, June 1905, Tanga. D. Ill 7. A. 

 Ill .3. L. lat. 3. 



Depth of body 3 3 /4 times in total length without caudal; length of head 4 times in 

 total length without caudal. Snout much shorter than eye which is contained about 

 .'>' -i times in length of head. Interorbital width about 2 3 /7 times in length of head. 

 Barbels short, posterior longer, about equal to diameter of eye. Origin of dorsal equally 

 distant from snout and root of caudal. Last simple ray of dorsal not enlarged, not 

 serrated a little shorter than head; dorsal not emarginate. Ventrals situated in front 

 of the vertical through the origin of the dorsal. Pectoral not reaching base of ventral, 

 tip of ventral just reaching vent. Caudal peduncle almost twice as long as deep, (i 

 scales between lateral line and origin of dorsal, 3 scales between lateral line and base 

 of ventral. Silvery, a somewhat darker lateral streak, a black spot at the root of the 

 caudal, a cloudy spot at the base of anal. 



Length of specimen 44 mm. 



This species is apparently related to B. amphigramma BouLENGER 2 from Nairobi 

 I viver, Kilimandjaro, which, however, has 35 36 scales in the lateral line which is black- 

 ish, snout and eye equal, length of head shorter than depth of body, shorter barbels, 

 4 scales between lateral line and ventral. 



The 10 species of Barbx* hitherto known from the Kilimandjaro-Meru district may 

 be distinguished with the aid of the following table. 



I. Last simple ray of dorsal enlarged, serrated behind. 



a) more than 35 scales in lateral line B. i>i(irr<>j>ri*tix n 



b) less than 32 scales in lateral line.
