found on the ground after heavy rains. I never met with 

 living specimens during the dry season, viz., from April to 

 October. 



Mterize River. The Mterize River is a tributary of 

 the Loangwa, and flows 50 miles South of Petauke, 

 through well-wooded and hilly country. Elevation, 2,000 

 feet. 



Loangwa River. A few species came from the main 

 bed of this important river, say at lat. i5°3o'. Elevation, 

 1,700 feet. 



The neighbourhood of this river and its tributaries 

 was found poor in mollusca, perhaps owing to the scarcity 

 of limestone. 



Alala Plateau. The Alala Plateau lies due West of 

 the Mchinga escarpment. More open country prevails 

 here, with large stretches of grass land. (September 

 15 — 20, 1905.) Elevation 4,000 feet. 



Kafue River. A few shells were collected on the 

 banks of a small stream at Ndola, a Government Station 

 near the Kafue River. The country is fairly open, but 

 with patches of very dense forest in the proximity of 

 streams. Elevation 4,000 feet. 



Kapopo* The famous limestone pool near Kapopo 

 was visited 26th and 27th October, 1905. Judging by 

 the great abundance of dead shells, mollusca must here 

 be plentiful as regards individuals, though the number of 

 actual species is apparently very limited. Country more 

 or less open, with forest-patches as at Ndola, and about 

 the same elevation (4,000 feet). Mollusca are known to 

 the natives as " Mkorno," and many of the larger terres- 

 trial species are dried and eaten by the people of the 

 Alamba Tribe in this neighbourhood (Kapopo), but not, 

 so far as can be ascertained, elsewhere. S. A. N. 



*N.B. — In Keith Johnston's Atlas (Ed. 1905) Kapopo is spelt Chepopo.
