This is a beautiful species, between H. gloriosa Pfeiffer and H. 

 Ibaraoensis Angas, but nearer to the latter one. It is however 

 smaller, more globose, the aperture is larger, of a more oblique 

 shape and the columellar margin is thicker. 



Ampelita Rohillardi Angas. 



This does not appear to be a very variable species. The shell is 

 more or less depressed and the upper line is sometimes wanting.

1 at first supposed this species might be //. Favanni Lam., var. p 

 •elongatula, of Crosse (Journ. de Conch., 1868, p. 185), also found 

 in southern Madagascar, but the present form is quite different in
