oi conjecture. Into this category fall the 4 shells collected by Junod ; 

 they are all much worn, showing the broad brown band which is character- 

 istic of C.ferruginea, but with rather more convex whorls than are usually 

 seen in fresh examples of that species.

Hab. Mozambique. R. Rovuma (Kirk, fide Dohrn). 



I cannot trace Kirk's specimen in the British Museum, where it might 

 be expected to be found. I consider it almost certain, however, that it 

 must have been an immature example oi ferruginea, rather than Olivier's 

 Egyptian species.

In 1915 I proved that the name coacta, as originally applied by Meuschen, 

 was void, and that the Melania coacta quoted by von Martens should bear 

 the latter's name as author. However, on p. 183 of D.-O.-A. von Martens 

 places vouamica Bgt. in the synonymy of coacta Meusch., while on p. 198 

 he admits that coacta Meusch., not crenularis Desh., is the correct identifi- 

 cation of the shells collected by Peters in Mozambique. Under these 

 circumstances. Tiara vouamica Bgt. (1889) has precedence of T. coacta 

 Mts. (1897), which must be relegated to synonymy.
