TRAVELS IN CENTRAL AFRICA. 
Chrysiclithys macrops, Gthr. 
D. 1/6. A. 11. P. 1/8. V. 6. 
This species is very closely allied to C, auratus, but it differs in 
having the upper side of the head covered with thin skin only^ so 
that portions of the hone are nearly naked and granulated ; its eye 
is considerably larger, the diameter being more than one-fifth of 
the length of the head. The first dorsal ray and the upper caudal 
lobe are prolonged into filaments. 
It appears to be peculiar to the upper parts of the river, and 
occurs also in West Africa. 
Clarotes. 
Body scaleless. Adipose fin subdivided into rays, and with a 
strong spine in old individuals; a short dorsal fin with a pungent 
spine and with six soft rays; anal fin short. Barbels eight ; branchi- 
ostegal membranes scarcely united below the throat. Vomerine 
teeth in two transverse bands, which are not confluent with the 
palatine teeth. Eyes with a free orbital margin. Caudal forked ; 
ventral with six rays. 
This genus is scarcely different from Chrysiclithys, the division 
of the adipose fin into rays being dependent on age. In all other 
respects, except in the unimportant modification of the arrangement 
of the palatine teeth, Clarotes is identical with Chrysiclithys.
