188 HELIX-FRUTICICOLA. 



little acute. Whorls 4J-5I, 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.)

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.

Nearly covered-perforate, depressed-globose, rather thin, subtrans- 

 lucid, rudely and irregularly costate-striate, especially above; all 

 over beset with short, yellowish, regularly arranged hairs ; horny- 

 rufous, with an obsolete whitish band. Whorls 6. Peristome very 

 thin, with a very distinct white thickening rather deeply removed

 the umbilicus.
