. Bulletin of the British Museum (Natural History). LAKE GEORGE HAPLOCHROMIS SPECIES 225 (Greenwood 1959a). However, the Lake George fishes seem to have rather more massive bones (and greater molarization of the teeth) than do fishes from Lake Nakavah. In the two smallest Lake George specimens (45 and 46 mm standard length) the bone is only a Uttle less developed than in a comparable-sized specimen from Lake Victoria, and there is equal molarization of the teeth [see fig. 3 top right, in Greenwood 1959a). The 80 mm standard length Lake George fish has a bone comparable with that of the 123 mm

The 80 mm standard length Lake George fish has a bone comparable with that of the 123 mm standard length Lake Nakavali specimen figured {op. cit.), but the 104 mm standard length fish has a relatively less massive bone which is comparable with the same specimen irom Lake Fig. 39. Astatoreochromis alluaudi. A Lake Victoria specimen. From Boulenger, Fishes of the Nile. The ratio of head length to pharyngeal bone width (measured from tip to tip of the upper arms) is in the range 2-9-3-0 [see Greenwood, op. cit.). Vertebral counts for the 4 specimens are 13 + 16 (), 13 + 15 () and 14 + 15 (). Ecology. Little more can be added to our knowledge of this species in Lake George. The 4 specimens came from different areas of the lake, but a common feature for each locaUty is its proximity to the shore and the presence of rooted aquatic vegetation in the area. Only fragments of gastropod shells were found in the intestines of the larger fishes (80 and 104 mm standard length) ; the 2 smaller individuals (45 and 46 mm standard length) yielded fragmentary remains of chironomid larvae. HEMIHAPLOCHROMIS bidder, 1963 The primary generic distinction of this superficially Haplochromis-]ike taxon is its reproductive biology {see Wickler 1963). The two morphological characters that separate it from Haplochromis (at least those species occurring in Uganda) are :.
