H. TETUANENSIS Kobelt, 1881. PL 54, figs. 30-33. 



Covered perforate, globose conoidal, beautifully undulately gran- 

 ulate under the lens by the decussation of distinct incremental 

 striae and very fine spiral impressed lines ; rather thin, lustreless, 

 unicolored dirty yellow or with brown bands, sometimes coalescent ; 

 whorls 5, well rounded, separated by impressed sutures, the first 

 forming a projecting apex, the last inflated and briefly, deeply de- 

 flexed anteriorly ; aperture very oblique, lunate-rounded ; peristome 

 acute, labiate with white, the margins converging, and joined by a 

 callus, upper margin a little expanded, outer and basal margins 

 reflexed, columellar lip expanded over the perforation, and bearing 

 a strong dentiform fold inside. Diam. 20, alt. 17 mill. 



Mts. Beni Hosemar, at Tetuan, Morocco. 



Closely allied to If. bottgeri. 

 H. SICANOIDES Kobelt, 1881. PI. 54, figs. 17-19. 



Very slightly but always sensibly rimate, globose-subconoid, apex 

 exserted, rather thin but solid, unicolored whitish or yellowish, or 

 with brown or blackish bands of various widths, striatulate ; whorls 

 5, separated by distinct linear suture, the upper ones flattened, the 

 following more convex ; body-whorl inflated, abruptly descending 

 at aperture ; aperture very oblique, rotund-lunar ; peristome labiate 

 with white, slightly reflexed on the base, margins converging, joined 

 by a light callus ; columella with a strong callus, sometimes denti- 

 form below. Diam. 21, alt. 16 mill. (Kobelt.) 



Mts. Beni Hosemar, near Tetuan, Morocco. 



Very nearly allied to the Sicilian H. sicana, says Kobelt, but 

 constantly separated from that species, after an examination of sev- 

 eral hundred examples of each, by the umbilical rimation, of which 

 t<i(.'iina never has any indication, by the peculiar apex, and the less 

 reflected peristome. 



H. SICAXA Ferussac. PI. 54, figs. 13-16. 



Imperforate, globular or bullet-shaped, thin but rather solid, 

 whitish, unicolored or with three or four narrow brown or corneous 

 subcontiuuous bands, delicately opaquely striate, the surface decus- 

 sated by numerous fine incised spiral lines, base nearly smooth; 

 spire more or less elevated conic, obtuse; suture linear, but well 

 impressed and distinct; whorls 5-5 4, those of the spire somewhat 

 flattened, gradually increasing; body-whorl globose, rounded, very 

 convex below, somewhat constricted behind the aperture, rather 

 deeply deflexed anteriorly ; aperture small, rotund-lunar, very ob-
