transverse striae and slightly malleated; suture well im- 

 pressed ; eolumella whitish, internally broad ; labrum erectly 

 reflexed, the margins joined by a thin whitish callus; aper- 

 ture very broadly inversely auriform. Alt. 2, diam. maj. 2.25

Alaa keniana PRESTON, Proc. Zool. Soc. Lond., 1912, p. 189, 

 pi. 31, f. 6. 



The diameter assigned by Preston is probably an error for 

 1.25 mm. The sculpture described reminds one of Nesopupa 

 corrugata. Not seen by the writer. 



NEGULUS OBLIQUICOSTULATUS (Smith). PL 5, fig. 15. 



Shell minute, cylindric, pale brownish, rimate. Whorls 6, 

 a little convex, separated by a deep suture, ornamented with 

 arcuate, thin, very oblique riblets, the last slightly contracted 

 in front, a little ascending, somewhat impressed behind the 

 lip. Aperture rounded, subquadrate, about one-third tke 

 total length, scarcely toothed within ; peristome thin, narrowly 

 expanded throughout, the margins approaching above. 



Length 2, diam. 0.75 mm.; aperture % mm. long, % wide 

 (Smith).

Pupa obliquicostulata E. A. SMITH, Proc. Zool. Soc. Lon- 

 don, 1892, p. 268, pi. 22, f. 21. 



"This is a very minute species, with very oblique, slender 

 and somewhat remote costulae and no teeth within the aper- 

 ture (Smith). 



Systematic place doubtful ; it may be a Truncatellina, but 

 the sculpture and proportions seem more like Negulus. Not 

 seen by the writer.
