130 PUPOIDES, ADEN. 



11. PUPOIDES KURSIENSIS (Bourguignat). Shell perforate 

 (the perforation puiictiform), 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. S 1 /* 

 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 RAGIUS (Jousseaume). - - Shell rimate (the 

 rimatiou 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. cccnopictus cannot be 

 assimilated to any of the Arabian coenopict forms, being 

 sharply distinguished by the deviating and strongly ascend- 

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