The Non-Marine Mollusca of Portuguese East Africa. Ill 



NATAU 



RouGH Map of Lorenzo Marques. 



Showing the approximate position of most of the localities quoted. Of those not shown, 

 Mt Ven<^o is about 1.5 miles north of Macequece; the rivers Tristao and Inyam- 

 karrara axe near Andrada ; the R. Mtisherra cuts the B. and ^l. Railway some distance 

 east of Amatongas. I have been unable to find Masiene, Nyiwan, and Mungurumbe on 

 any available atlas, but all three localities are on, or not far from, the coast in the southern 

 portion of the territory.
