 p. 102. 



Differs from a variety of Subulina dunkeri which agrees 

 in general appearance, by the greater number of whorls in a 

 less length, the varnish-like gloss and more acute apex. It is 

 smaller than subulata, with about the same number of whorla 

 and a shorter mouth (Jickeli). 



8. H. SUBULATUS (Jickeli). PI. 58, figs. 58, 59. 



Shell imperforate, subulate, rather solid, thin, longitudin- 

 ally subcostulate-striate, the last whorl, under a lens, lightly 

 wrinkled spirally; pale greenish; suture somewhat oblique, 

 submarginate. Whorls 11, subplanulate, the last one-fourth 

 the length, descending, the base tapering. Aperture very 

 oblique, narrowly oval, acutely angular above, the base slightly 

 receding. Columella subarcuate, obliquely and rather shortly 

 truncate; outer lip somewhat arching forward above; basal 

 margin narrow. Length 27, diam. 6.5, alt. aperture 7.5, 

 width 3 mm.; penult, whorl 4 mm. high, 6 wide (Jick.). 



Northeastern Africa: On the road from Genda to Asmara, 

 and near Mekerka, on the Toquor, prov. Hamaszen, Abyssinia, 

 under the bark of logs.

This species is narrower than the typical form of variabilis 

 Jick., and differs from the third variety, C., by its spiral 

 wrinkles, narrower mouth, less convex whorls and thicker 

 shell. 



9. H. SUAVEOLANS (Jickeli). PI. 58, figs. 56, 57. 



Shell imperforate, subulate, under a lens seen to be longi- 

 tudinally very finely striate, very glossy, hyaline, waxen. 

 Spire turrited, the apex rather obtuse ; suture deep, somewhat 

 margined. Whorls 9, swollen, the last scarcely equaling one- 

 third the total length, very slightly angular at the periphery.
