or posterior on either side, the remaining 2 being situated 
a little further inwards in the interspace between the median 
and lateral pairs. The 8 outer teeth are tricuspid, the 
8 inner of the uninterrupted series are much larger. Hach 
tooth of the latter series has two transverse rows of cusps, 
the outer usually consisting of two cusps and the inner of 
three or more. The cusps of the inner row are larger, espe- 
cially the middle one. All teeth are brownish. ‘There are $ 
pluri- (5-7-) cuspid teeth in an uninterrupted series in the 
lower jaw, and behind these a pair of conical fangs. The 
fangs are less brown than the large middle cusps of the 
pluricuspid mandibular teeth. 
The second infraorbital is longer than the diameter of the 
eye. The pectorals are longer than the ventrals. 
The tips of the pectorals are about as far from the base of 
the ventrals as the tips of the latter are from the anus—that 
is, about 14 centim. in the largest specimens. The distance 
between the base of the pectorals and the snout is about half 
of the measurement expressing the distance between the 
snout and the base of ventrals. The caudal is deeply cleft, 
the outer rays being more than twice as long as the middle 
ones, or, in other words, the latter being only # of the former. 
The colour of the preserved fishes seems to indicate that the 
colour of the living fish may have been brownish olive above 
and golden or silvery below. ‘There might have been a dusky 
longitudinal band along the third row of scales counted from 
above; but I am very uncertain about this, as it is most con- 
spicuous in such places where the seales are lost, but hardly 
visible where the scales remain. A black blotch situated on 
the body behind the opercle on a level with the eye, and on 
a vertical line drawn between the first and second third of the 
pectoral, is well visible on all specimens. Caudal fin reddish 
orange, perhaps with dusky border. Outer half of dorsal 
reddish orange, its basal half probably dusky. 
Five specimens, measuring from 178 to 210 millim. in 
length, from the Meme River, far inland. 
J am unable to find any features by which this fish could 
be distinguished from Riippell’s species as it is described in 
the literature. It thus appears to be widely distributed, as 
it is known from the Nile, Lake Victoria, Lake Rudolf, 
Senegal, Gambia, and Niger, but hitherto not from the 
Cameroon.
