76 HYALINIA NITIDULA. 
The H. hiulea by a consensus of opinion is regarded as a larger and more fully 
developed form of the present species in its broad sense, although Heer Schepmann 
has pointed out that, in the Styrian specimen examined by him, the radula appears 
to show mueli larger teeth than either nitidula or nitens, and only possesses about 
fifty-five longitudinal rows, with but three laterals on each side of the central tooth.

SHELL smaller and more strongly striate than in type, mouth more cireular and 
much deflected. 
The sub-var. dutaillyana is smaller, with more impressed suture, and more 
oblique and narrowly oblong aperture. 
The sub-var. minor is described as 6-7 mill. in diam. and 3 mill. in altitude, 
with a less dilated last whorl, and as more northern in its distribution. 
GERMANY.
