Lake Tanganyika: originally described from specimens obtained at Ujiji, on the 
eastern shore, by E. C. Hore; Kituta; Kala; Moliro; Sumbu; Kalamba (W. A. 
Cunnington Coll.); northern end (O. Baumann Coll.); Ufipa; Mbwe (Lechaptois 
Coll.). 
Germain, following Moore, believes that the typical form of the species is 
restricted to the central portion of the Lake. But in Stappers’ collection it is repre- 
sented by specimens collected all along the western shore: Uvira; at the mouth 
of the little Ruzizi; Tulo; off Tumpa; Baraka; bay of Tempwe; off Songwe; off 
the mouth of the Sambala; bay of the Luvu; pond of Gongwe near Toa; Toa; bay 
of Kilewa; bay of Kasakalawe; off the shore between Moba and the Lobozi ; between 
Vua and Moliro; off Moliro. It lives in the littoral zone between the shore and a 
depth of 20 meters. W. A. Cunnington also found keeled and non-carinate specimens 
together at the southern end of the lake, so that E. A. Smith concludes “‘that Mr. 
Moore’s idea of the local distribution of this species appears to be, ina measure, in- 
correct.”
