locality mentioned; not A. obliquus Broderip and Sowerby, 1832. B. Walker lists 
this as a dubious synonym of Burnupia stenochorias (Melvill and Ponsonby).

Busisi, Lake Victoria. It is said to be in large part flat, but with a steeply raised, 
blunt apex; concentrically striate; the apex with radial rows of impressed punctures. 
Length, 2.3 mm.; width, fully two-thirds of the length; height, two-fifths of the 
length. Dautzenberg and Germain (1914, Rev. Zool. Afric., IV, 1, p. 47) have re- 
corded this species from the Lualaba River at Kalengwe and Lake Moero at Lukon- 
zolwa (both J. Bequaert Coll.). The specimens from Kalengwe, which we have seen, 
are in our opinion not stuhlmanni and we describe them below as Burnupia walkert. 
We have not seen specimens from Lake Moero.
