312 DR. A. GUNTHER ON REPTILES AND FISHES [Juné 28, 
CHROMIS LATERISTRIGA. 
D2 A... P. 14.5 %. lat. 38... 1. transy..6/1 25 
9—10° * g—-10° 
Teeth very small. Scales below the eye in four series ; eye rather 
small. Caudal fin scaly. A black band runs from the nape of the 
neck, along the upper part of the side, to the base of the caudal fin. 
The skins of two examples have been preserved; the largest, 
10 inches long, is from Lake Nyassa. 
HEMICHROMIS INTERMEDIUS. 
D.. ALS. L. lat. 34. L. transv. 4/10. 
This species connects Chromis and Hemichromis, having the general 
habit of the former genus, and the conical teeth of the latter. The 
height. of the body is contained twice and three-fifths in the total 
length (without caudal); the length of the head nearly thrice. Head 
not much longer than high; snout rather elevated, and somewhat 
shorter than the postorbital portion of the head. Teeth minute, 
conical, of equal size, in a double series in the upper jaw as well as 
in the lower. The lower jaw projects a little beyond the upper, and 
the maxillary terminates somewhat before the vertical from the front 
margin of the:orbit. Preeorbital nearly square, and scarcely wider 
than the orbit. The naked preeopercular limb is higher than long, 
and at the angle narrower than the scaly part of the cheek, the scales 
being arranged in three series. The dorsal fin commences above the 
upper end of the gill-opening; the spines are slender, and rapidly 
increase in length posteriorly, the length of the last being two-fifths 
of that of the head. The soft rays are long, increasing in length 
to the sixth and seventh, which extend nearly to the middle of the 
caudal fin when laid backwards. Anal spines stout; caudal emar- 
ginate, densely scaly ; pectoral and ventral equal in length, the latter 
extending to the soft portion of the anal. 
Back with some obscure cross bands; interradial membrane of the 
soft dorsal with a series of ocelli; anal with large round whitish 
spots. 
A single example, 8 inches long, is in the collection ; it is probably 
from Lake Nyassa, 
HeMICHROMIS ROBUSTUS. 
D. af A =: L. lat. 37. _ L. transv. 6/14. 
The length of the head is somewhat more than the height of the 
body, which is one-third of the total length (without caudal). Snout 
compressed, long, rather high, somewhat shorter than the postorbital 
portion of the head. Teeth conical, of moderate strength, rather 
closely set, and slightly bent at the tip ; they form two series in the 
upper jaw, and one in the lower. The lower jaw projects somewhat 
beyond the upper, and the maxillary extends nearly to below the 
centre of the orbit. Przeorbital bone much wider than the orbit ; the 
scales on the cheek are small, arranged in about ten series. Dorsal
