each elbow and heel; the hind margin of the fore arm and of the 
tarsus yellow. Upper lip yellow, lower parts whitish. 
A single adult female specimen from the Rovuma Bay is in the 
collection. 
Hyperouivs cirrinus. (Pl. XXVII. fig. 2.) 
Tympanum hidden ; tongue deeply notched behind ; snout rather 
short ; upper parts with small scattered tubercles ; the region between 
eye and axil finely tubercular. Entirely uniform lemon-coloured 
above and below. 
I have examined two male specimens, one from the Senegal, and 
the other from the Zambesi Expedition. 
Hyperouius microps. (Pl. XXVII. fig. 3.) 
Tympanum hidden ; tongue broad and deeply notched behind ; 
eye comparatively small, shorter than the snout, which has a sharpish 
canthus rostralis ; upper parts smooth ; belly finely and equally gra- 
nulated. Greyish olive above ; a whitish line runs along the canthus 
rostralis, and is continued behind the eye along the anterior half of 
the length of the body ; its rostral portion has a brown inferior mar- 
gin; upper parts of the head sometimes with a few minute brown 
dots. Lower parts whitish. 
This is one of the smallest species, an adult male being only 
10 lines long; it has the gular sac fully developed, and is from Ro- 
vuma Bay.

D. Gs AL. L. lat. 33. L, transy. 4/14. 
The height of the body is two-fifths of the total length (without 
caudal) ; the length of the head more than one-third. Teeth very 
small, in about three series in both jaws; there are about forty on 
each side in the front series of the upper:jaw. The naked portion 
of the preeoperculum is a little higher than long, and at the angle 
as wide as the scaly part of the cheek below the eye. Scales on the 
cheek in two series. Dorsal spines of moderate strength, not so 
strong as those of the anal fin; the dorsal rays do not extend to the 
caudal fin, when laid backwards. Caudal densely covered with mi- 
nute scales. Pectoral long, sometimes extending beyond the middle 
of the anal. Silvery, with six black cross bands, the first in the 
middle of the nape; the second descends from the origin of the dorsal; 
the fifth from its end; the last on the root of the caudal.’ .A black’ 
spot on the extremity of the operculum. : : 
This species is similar to C. niloticus; but it may be readily. - 
distinguished by its much larger head, densely scaly caudal fin, and 
black cross bands. Several specimens were collected on Lake Nyassa, 
the largest being one foot long. RS
