HELIX. 



This form is allied to H. rjlobularis, and especially to If.platychela, 

 but may be separated by several characters from both of these Sicilian 

 species. The peristome is nut so broadly expanded as in platychela, 

 nor is it so decidedly dentate as is usual in that species; and there 

 is not so obvious a flattening of the upper whorls as in the more 

 depressed forms (which are nearest to melitensis) of platychelt. 



Yar. CARUASLT: Pilsbry. PI. 62, fig. 54-56. 



Spire elevated, conoidal; aperture small and very oblique ; colora- 

 tion usually of zigzag brown strigations sometimes broken into 

 obscure bands above, and a narrow cordon of blotches below the per- 

 iphery.

H. PROVINCIALIS Benoit, 1842. PL 64, fig. 19, 20; pi. 60, figs. 74, 



75. 



Imperforate, depressed, slightly shining, solid, white, unicolored 

 or marked with four cordons of pale brown spots, irregularly 

 obliquely striate, and with microscopic spiral incised lines above, 

 less striate below; spire low conoid, blunt, but the apical whorl 

 slightly projecting, corneous; whorls 4^-5, the upper ones somewhat 

 flattened, the body-whorl depressed, (more so than in either the 

 .several preceding or following species) sub-angulate at its origin, 

 abruptly and deeply descending at the aperture, generally a little 

 indented around the axis below; aperture small, very oblique, trun- 

 cate-oval, slightly darkened and often fasciate within ; peristome 

 expanded, outer and basal margins reflected, terminations not con- 

 verging, baso-columellar portion appressed, callous and straightened 

 within, but not at all dentate. Diam. 17-19, alt. 12-14 mill. 



Sicily. 



H. saracena Benoit mss. is the same. 



The small oblique aperture, not dentate below (not even so much 

 as is shown in figs. 74, 75 of pi. 60) but callous, and the depressed 

 body-whorl will enable one to distinguish this species. There is 

 usually a faint brown spot at the insertion of the columella. 



H. RAGUS.E Kobelt, 1884. PL 68, fig. 17-19. 



Imperforate, depressed trochoidal, the base inflated, solid, slightly 

 shining, irregularly striate, under the lens showing spiral impressed 

 lines, grayish white, with obscure traces of bands of maculations; 

 whorls 5, the first !] smooth, convex, the apex a little exserted, sub- 

 mamillate, the following planulate, distinctly carinate in young
