162 HELIX-CANDIDULA. 



H. PSILORITANA v. Maltzan. PL 40, figs. 68, 69. 



Shell small, rather widely perforated or narrowly umbilicated, 

 depressed globose, strong; roughly striated, the last whorl rib- 

 striated. White, generally marked with three brown bands, of 

 which the upper one indicates the periphery and is broader than the 

 two lower, but sometimes it occurs also with 4 or 5 bands. The spire 

 is quite convex, with minute, pointed, brownish apex. There are 

 between 5 and 6 whorls, which are quite convex and widen extremely 

 slowly and regularly. The suture is linear, scarcely impressed, but 

 distinctly and under the lens quite finely crenulated. The last 

 whorl is rounded, hardly wider and very indistinctly descending in 

 front. The aperture is not very oblique, quite circular, but some- 

 what dilated transversely and moderately lunate ; the peristome is 

 acute and strongly white-lipped, the margins converge but are not 

 connected by a callus ; the upper margin is somewhat produced for- 

 ward. The basal margin slightly reflected and scarcely dilated at 

 the insertion. (jfiToft.)

H. DIENSIS v. Maltzan. PI. 40, figs. 75, 76. 



Shell narrowly perforated, depressed-conoidal, rather strongly and 

 regularly striated; solid, whitish with scarcely distinct brown bands. 

 Spire rather high with quite minute, dark apex. Six well rounded 

 whorls increasing very slowly but separated by a linear suture ; the 

 last whorl is scarcely widened, more or less distinctly obtusely 

 angulate at the periphery, and rounded below ; in front very shortly, 

 distinctly deflected. The aperture is oblique, round-ovate, distinctly 

 lunate ; peristome acute, having a not especially strong white lip 

 within ; the margin approaching slightly ; the upper is produced 

 throughout, the basal margin but very little reflected, and very little 

 dilated over the perforation. (Kob.) 



Alt. 7J, greater diarn. 1H, lesser 10 mill.
