246 HELIX. 



very pale, even when banded. The bands appear subtranslucent 

 from within. The columellar lip is expanded only in the immediate 

 vicinity of the umbilicus, and is closely appressed over it, differing 

 in this respect wholly froni H. ligata, with which Bourguignat com- 

 pares it. From H. cincta and its white variety pollinii, the differently 

 formed, less expanded basal lip and columella will separate it. 

 Kobelt has identified with this species a form of very different ap- 

 pearance; so different that I am inclined to believe it specifically 

 distinct. His description (translated) and copies of his figures (pi. 

 r >6, figs. 6, 13) are here given: 



8hell imperforate, globose, whitish, encircled with two or three 

 zones, rugose-striate, slightly shining; whorls 5, somewhat convex, 

 rapidly increasing, the last large, dilated, gently descending at the 

 aperture; aperture lunate-rotund, white within, slightly oblique; 

 peristome simple, thick, albolabiate within, the columellar margin 

 reflexed, appressed, dilated over the umbilical region, joined to the 

 upper lip by a thin callus. Diam, 42, alt. 42 mill. (Kobelt).

H. MELANOSTOMA Drapernaud. PL 56, figs. 7, 9. 



Imperforate, globular, opaque, somewhat shining, brownish or 

 fleshy white, unicolored, or with the upper part of the body-whorl 

 slightly darker, the darker portion distinctly defined, coarsely 

 obliquely striate, and with obsolesent spiral impressed lines; spire 

 conic., very short, the apex minute, obtuse, corneous; sutures linear, 

 but impressed; whorls 4, slightly convex, the inner gradually, the 

 last very rapidly widening, globose, scarcely indented at the axis, 

 gently descending anteriorly; aperture oblique, rotund-lunate, flesh- 

 colored within, its margins scarcely approaching; peristome simple, 

 obtuse, thickened, labiate within with deep brown; columellar mar- 

 gin deep chestnut colored, reflexed and appressed over the umbilical 

 tract, and joining the upper margin by a conspicuous black or deep 

 chestnut callus. Diam. 26, alt. 26 mill. 



Southern France; N Africa; Balearic Is. 



Easily recognized by the compact, globose form and blackish 

 aperture. The largest specimen I have seen (from the Balearic Is.) 

 measures 35 mill, diam., but Bourgingnat gives for an Algieriau 

 example these measurements: diam. 42, alt. 50 mill. !
