130 PUPOIDES, ADEN. 



11. PUPOIDES KURSIENSIS (Bourguignat). Shell perforate 

 (the perforation punctiform), elongate-ventricose, slightly 

 fusiform, glossy, pale corneous, almost smooth, but under a 

 very strong lens, very sharply and obliquely radiatulate. 

 Spire somewhat swollen, acuminate-oblong; apex glossy, 

 smooth, a little whitish, very obtuse as though mamillate. 

 Whorls 6 (the upper convexly rotund, the third a little con- 

 vex), regularly increasing, separated by a little-impressed 

 suture, the last whorl nearly % the length, narrow, little 

 convex, suddenly, slightly ascending at the insertion of the 

 lip. Aperture very oblique, quite small, lunate, oblong, 

 rather narrow transversely; peristome flatly expanded and a 

 little reflected. Columella straight, immersed ; margins re- 

 mote, joined by a very thin callus, a hardly noticeable tooth- 

 like callus at the insertion of the lip. Length 5, diam. 3% 

 mm. (Bgt.). 



Arabia : Kursi, near Aden.

It seems to be much more ventricose than P. C. samavaensis 

 or even P. tutulus, and must be a distinct species if Bour- 

 guignat's measurements are correct. 



12. PUPOIDES BAGIUS (Jousseaume). Shell rimate (the 

 rimation deep, straightly elongate), minute, oblong, subtrans- 

 lucid, a little glossy, pale corneous, finely striatulate. Spire 

 oblong, rather regularly tapering, obtuse at the apex. Whorls 

 6, convex, as though swollen, separated by a deep suture, the 

 last whorl rounded, relatively strongly ascending, and some- 

 what bag-shaped. Aperture nearly vertical, semiovate, con- 

 spicuously turned towards the right; peristome white-lipped 

 and reflected throughout, the margins joined by a thin callus 

 bearing a strong tubercle on the right. Length 4, diam. 2, 

 alt. apert. 1.25 mm. (Jouss.). 



Arabia: near Aden in the drift of a small stream; also in 

 the environs of Massaua on the Abyssinian side (Jousseaume}.

This Bulime, of the series of B. ccenopictus cannot be 

 assimilated to any of the Arabian ccenopict forms, being 

 sharply distinguished by the deviating and strongly ascend- 

 ing last whorl, by the excentric aperture, carried far to the
