The series overlies gneisses and ampbibolites (with a north- 

 north-westei'ly and south-sonth-easterl)' strike). In searching for 

 the extension of these beds the Author found them to be completely 

 denuded on the south, while on the north they disappear beneath 

 the basalt-plateau. Marching up the Kuja Valley, he found the 

 upper beds lying on old andesite 15 miles inland, on the line of 

 strike. Evidence is adduced of the lake having stood about 

 330 feet above its present level, and of a rejuvenation of the rivers 

 since the formation of a gneissic peneplain, above which the Kisii 

 Highlands rise in steep escarpments of ripple-marked, vinfossiliferous, 

 quartzitic sandstones (probably Devonian), separated from the 

 underlying gneisses and schists by an extensive dolerite-sill. From 

 Kisii the peneplain was traversed to the region of nepheline-lavas 

 near Homa Bay. Lake Simbi, an explosion-crater, was investi- 

 gated; and a Pliocene series was found north of Homa Mountain. 



The vertebrate remains described by Dr. C. W. Andrews include 

 Proboscidea, Hyracoidea, Artiodactyla, llodentia, and lleptilia, and 

 fully support the suggested occurrence of Lower Miocene deposits 

 on the shores of the Victoria Nyanza. A deposit of probably 

 Pliocene age yielded a new (?) species of Elcphas, alec bones of 

 antelopes and baboons. 



The non-marine moUusca associated with the Miocene verte- 

 brates are freshwater and terrestrial shells w^hich all belong 

 to existing species. Only Am/mllaria, however, still occurs in 

 the Victoria Nyanza, while Lanistes carinatus is not found nearer 

 than the Tana lliver, and the nearest recorded locality for 

 Cleojmtra hulimouJes is in the Lake lludolf region and Mombasa. 

 Among the terrestrial shells, Burtoa is the sole genus occurring 

 near the Victoria Nyan/.a ; the other forms (Cerastiis, Tropidophora, 

 Achatiua) are found at considerable distances therefrom. The total 

 absence of Pelecypoda is also interesting.
