. Bulletin of the British Museum (Natural History). LAKE GEORGE HAPLOCHROMIS SPECIES 197 Gill rakers. On the lower part of the first gill arch there are 8 rakers of which the lowermost is reduced, the following 2 are stout and the remaining 5 are relatively slender. Pseudorakers are present but weakly Fig. 26. Haplochromis labiatus. Lake George specimen. Scales. Ctenoid, lateral line with 30 scales, cheek with 3 rows. There are 5J scales between the upper lateral hne and the dorsal fin origin, 7 between the pectoral and the pelvic fin bases. Scales on the thoracic region are small.

On the lower part of the first gill arch there are 8 rakers of which the lowermost is reduced, the following 2 are stout and the remaining 5 are relatively slender. Pseudorakers are present but weakly Fig. 26. Haplochromis labiatus. Lake George specimen. Scales. Ctenoid, lateral line with 30 scales, cheek with 3 rows. There are 5J scales between the upper lateral hne and the dorsal fin origin, 7 between the pectoral and the pelvic fin bases. Scales on the thoracic region are small. Fins. Dorsal with 15 spines and 10 branched rays, anal with 3 spines and 9 branched rays. Pectoral 31-0 per cent of standard length, 96-5 per cent of the head. Caudal scaled on its basal half ; the distal margin is frayed but was apparently truncate when intact. Pelvics with the first ray barely produced. Teeth of the outer row in both jaws are stout and somewhat compressed (text-fig. 27). In the upper jaw the two posterior teeth on each side are unicuspid, but the remainder are unequally bicuspid, with the crown vertically orientated. There are 32 teeth in this row. All teeth in the lower jaw are bicuspid, but those located posteriorly are smaller than the more anterior teeth. Anteriorly, the lower jaw teeth are shghtly procum- bent, each tooth lying forward at an angle of about 80° to the horizontal. The inner teeth in both jaws are small and tricuspid, and are arranged in 3 rows in the upper jaw and 2 in the lower. The lower pharyngeal bone is moderately stout and its dentigerous area is slightly broader than long (i-i times). The teeth are compressed and cuspidate, with the posterior teeth of the median rows coarser than the others. The vertebral count is 13 abdominal -1- 16 caudal centra. (The type has 13 + 17 centra.) Only preserved coloration is known. The body is brownish above and shades to silvery on the ventral flanks, chest and belly ; the entire head is brownish.
