The Non-Marine Mollusca of Portuguese East Africa. 169 



The British Museum contains 3 examples of this little known species, of 

 which the type and another are labelled " Cape Natal," and the third as 

 above. It is open to question whether they were really collected in two 

 different localities, but the species does not seem to have been rediscovered 

 since the days of Plant, and its exact habitat cannot therefore be definitely 

 stated. The shells resemble A. transvaalensis, Smith, in colour, sculpture, 

 and texture, but are considerably larger and comparatively more obese, 

 measuring respectively 62x30, 64x31, and 65x29i mm.

A very distinct member of the small group of narrow shells which 

 includes A. pfeifferi Dkr. and ustulata Lam. The type is immature, the 

 measurements of a full grown adult being 63-2 X 24-3 mm.

Hab. Mozambique, ex sacks of grain (Ancey). 



I have been unable to collect any information about this so-called 

 Limicolaria, but the description recalls Ps. boivini (Morel.), and I suspect 

 that sculpturata may be identical with Ancey 's unpublished Limicolaria 

 borellii, which I show hereafter, p. 171, to be identical with Morelet's species. 



Genus Limicena nov. 



Shell bulimoid when adult, perforate, columella not truncate, proto- 

 conch (2| whorls) sculptured with 8 or 9 strong microscopic spiral costulae, 

 remainder weakly transversely striate.
