916 MR, G, A. BOULENGER ON NEW FISHES [Dee. 1, 
Most nearly allied to C. callipterus, Gthr.’, with which it agrees 
in the dentition. 22-30 teeth on each side of the outer series of the 
upper jaw. Depth of body 23 to 2? in total length, length of head 
3 to 33 times. Eye nearly equally distant from the upper lip and 
the gill-opening, its diameter 4 times in length of head, 13 times 
in interorbital width, and equal to preorbital; maxillary not 
extending quite to below anterior border of eye; four series of 
scales on the cheek below the eye; large scales on the opercle and 
on the interorbital region ; preopercular limbs forming a right 
angle. Gull-rakers very short, 8 on lower part of anterior arch. 
Dorsal XVI 12-13; spines increasing in length to the last, which 
is 3 length of head. Pectoral pointed, a little longer than the 
head ; ventrals shorter, not reaching the vent. Anal III 9-10; 
third spine longest, as long as middle dorsals. Caudal rounded (?). 
Caudal peduncle not longer than deep. Scales rough but not 
denticulate, 30-32 ing lat. 1. paces Body without distinct 
markings; snout and a spot on the opercle blackish; dorsal fin 
with blackish spots and oblique bars. 
Total length 220 millim. 
Three specimens. 
OREOCHROMIS SHIRANUS, sp. n. (Fig. 2, p. 917.) 
Teeth very small, in 5 to 7 series in the upper jaw, the outer 
with notched, bicuspid, brown crowns, the others tricuspid; 35 to 
47 teeth on each side of the outer series of the upper jaw. Depth 
of body 23 to 23 in total length, length of head 3 times. Eye 
equally distant from the end of the snout and the gill-opening, its 
diameter 4 to 4} times in length of head, 13 to 2 times in inter- 
orbital width, and nearly equal to preorbital; maxillary not 
extending to below anterior border of eye; two series of scales 
on the cheek below the eye, lower largest; opercle scaleless ; 
preopercular limbs forming a right angle. Gill-rakers short, 
15-18 on lower part of anterior arch. Dorsal XVI-XVII 10-12; 
spines increasing in length to the last, which is 4 length of head 
or a little less. Pectoral ? (broken); ventral reaching vent. 
Anal 1V 9-10; fourth spine longest, as long as and stronger 
than middle dorsals. Caudal peduncle not longer than deep. 
Scales rough but not denticulate, 31-32 =; lat. 1. ie Nothing 
can be said of the coloration, the condition of the specimens being 
too bad. 
Total length 210 millim. 
Five specimens. 
? A comparison with the original description (P. Z. 8. 1893, p. 623) is 
misleading in so far as the number of dorsal spines is given as 14, which is 
exceptional, the normal number being 15 or 16. Out of the 5 type specimens, 
only the one figured (from Zomba) has 14 spines; two, including the largest 
specimen received from the Rey. J. A. Williams, have 15 spines; the other 
twe have 16.
