TEAVELS IN CENTEAL AFEICA . 
There are three series of scales between the lateral line and the 
root of the ventral fin. Upper and lower lip sometimes with a well 
developed lobe, nearly as long as the eye, sometimes without a trace 
of it. Body strongly compressed^ back elevated below the origin 
of the dorsal fin^ where the height of the body is one-third of the 
total length (without caudal) . The length of the head is contained 
four times and one-third in the same length. Snout somewhat 
pointed^ with thick lips ; mouth inferior. Caudal deeply forked. 
Very common in all parts of the river^ and eaten by the Arabs. 
Attains to a length of two feet.

The osseous dorsal ray is rather feeble, smooth. There are three 
series of scales between the lateral line and the root of the ventral 
fin. Body compressed and somewhat elevated, as in the roach, 
its depth being one-third of the total length (without caudal) ; 
head small, its length being rather less than one-fourth of the total 
(without caudal) ; its depth equals its length (without snout) . Eye 
rather large, equal to the length of the snout, two-sevenths of that 
of the head, and two-thirds of the width of the interorbital space, 
which is convex. Mouth anterior; lips thin, the lower with the 
transverse fold interrupted in the middle. Dorsal fin rather ele- 
vated : its origin is somewhat nearer to the end of the snout than 
to the root of the caudal. Caudal fin deeply forked. Bright silver}^, 
with a bluish stripe from the scapula to the middle of the caudal.
