188 HELIX-FRUTICICOLA. 



little acute. Whorls 41-51, slightly convex, separated by an 

 impressed suture, very distinctly and densely subcostulate-striate, 

 the striae especially at the sutures wrinkle-waved ; last whorl very 

 slightly subangulated in the middle, and uni-cingulate with whitish, 

 shortly descending at the aperture and surrounded with an orange 

 or yellow band there. Aperture very oblique, rather large, excised- 

 subcircular, slightly wider than high, having a usually very strong 

 white lip a distance within ; peristome simple, acute, shortly 

 reflexed at the columella, the margins widely separated. (Bttg.')

 Syst, Geog. u. Biol. der Thiere), iv, p. 943, t. 27, f. 12a-d. (Dec. 27,

The shell varies greatly in size, color, thickness and strength of 

 the lip-callus, being constant in the peripheral band and hirsuteness 

 only ; but in fully grown individuals the hairs seem to be lost, leav- 

 ing a shining, densely pitted surface. The hairs are closer than in 

 rubiginosa Schm., but they are shorter. The species resembles 

 Trichia in the hairy coat, but Carthusiana in the thickened lip, etc.
