OF FISHES FROM LAKE TANGANYIKA, ih 
brown lateral stripe from the upper lip, through the eye, to the base of the caudal, 
where it expands into a spot; another dark brown stripe from the vertex along the 
base of the dorsal; a few brown spots on the dorsal; anal edged with dark brown; a 
black bar at the base of the pectoral, which is white. 
Total length 78 millim. 
‘Two specimens from Mbity Rocks. 
9. TELMATOCHROMIS TEMPORALIS, sp. n. (Plate IL. fig. 3.) 
8 to 12 enlarged conical teeth, tipped with brown, in the outer row in each jaw. 
Depth of body 3} to 53 times in total length ; length of head 3 to 33. Snout descending 
in a strong curve, 13 as long as the diameter of the eye, which is 44 times in length of 
head and a little less than interorbital width; maxillary extending to below anterior 
border of eye; head naked, or with a few deciduous scales on the opercles. Gill- 
rakers very short and few. Dorsal XX—XXI 6-7; spines increasing in length to the 
last, which equals 4 to 3 length of head; middle soft rays produced, 3 to # length of 
head. Pectoral # length of head. Ventral produced into a filament, extending beyond 
origin of anal. Anal VI-VII 6-7; spines increasing in length to the last, which 
equals or slightly exceeds last dorsal; soft rays produced, like the dorsals. Caudal 
rounded. Caudal peduncle as long as deep. Scales 43-46 S lat. 1. oa Brown, 
with small round darker spots between the dorsal, anal, and caudal rays; a dark 
horizontal streak behind the eye; a dark bar at base of pectoral. 
Total length 85 millim. 
Three specimens from Kinyamkolo, and one from Mbity Rocks. 
The deep anterior groove of the skull, in which the ascending processes of the pre- 
maxillaries are received, extends to the anterior third of the orbits. and the strong 
occipital crest is prolonged forward to it; parietal crests are entirely absent; the 
chain of suborbital bones is very slender. None of the ribs are sessile, being inserted 
on a step at the back of the transverse processes of the vertebre at a short distance 
from the centre ; all bear epipleurals ; only the last precaudal vertebra has a hemal 
bridge. 
JULIDOCHROMIS, g. n. 
Body elongate ; scales ctenoid. Jaws very narrow, with a few curved canines in 
front, the outer of which are very large and tusk-like, followed on the sides and behind 
by minute conical teeth forming a narrow band. Maxillary exposed. Dorsal with 22 
to 24 spines, anal with 8 or 9. Vertebre 34 (17-+17). 
This genus represents an exaggerated type of Lamprologus. The very specialized 
dentition and the general aspect remind one of the Julidine Labride, whence the 
name proposed.
