132 HELIX. 



The synonymy includes H. lactea Fer. and some other authors, 

 H. canariensis Villa, H. punctatissima Jen., H. bredeana, H. engas- 

 tora, If. stomatodea, H. bandotiana, H. calendyma Bourguignat. 



Differs from H. lactea in having a thinner, smoother shell, bands 

 more disposed to be coalescent and clouded, and basal callus not so 

 decidedly dentate within. 



Var. APALOLENA Bourguignat. PI. 64, figs. 4, 5. 



Differs from the typical form in its more depressed outline, thinner, 

 smoother shell ; whorls more rapidly increasing in width, and con- 

 sequently aperture more elongated transversely. 



Mediterranean littoral region of Spain and France ; Balearic Is. 



H. BLEICHERI Paladilhe. PL 39, fig. 98. 



Imperforate, depressed globose, spire depressed conic, thick, with 

 fine, curved, irregular incremental stride, crossed by broken revolv- 

 ing lines, as in the preceding forms, and with vermiform transversely 

 elongated minute wrinkles, and quadri-fasciata, when young some- 

 what angulate around periphery ; fauces and columella margin deep 

 castaneous ; aperture very dark within, rotund-lunar, very oblique, 

 more regularly oval than in H. punctata; peristome narrowly re- 

 ilexed, its ends converging, connected by a thin castaneous callus. 



Morocco. 



Probably a variety of H. lactea Miiller. 



H. TINGITANA Paladilhe. PL 64, figs. 1-3. 



Imperforate, globose-conic, solid, opaque, shining, with fine wrink- 

 les, undulating revolving lines, and regular incremental stria? ; 

 whorls 4-5, encircled by four or five yellowish-purple unbroken 

 bands, the upper ones usually confluent ; spire depressed-conoidal, 

 upper whorls rather flattened, rapidly increasing, abruptly deflected 

 at aperture ; aperture large, truncate-oval ; peristome regularly 

 curved above, straighter below, ends slightly converging, connected 

 by a light callus ; outer lip broadly expanded, light colored ; throat 

 and thickened colurnellar callus deep brown. Diam. 29 mill. 



Between Tanger and Meknes. 



Specimens before me are decidedly larger than above indicated. 



H. LUCASII Deshayes. PL 40, figs. 14, 15. 



Imperforate, orbicularly depressed, smooth, white, with five broad 

 dark brown bands ; spire short ; apex brown and white, obtuse,
