HYGROMIA UMBROSA. 67 
Var. cecoscia (Bourguignat ms. 1879) Servain. 
Helix wcoscia Servain, Ann. Malac., 1884, vol. i., p. 39. 
Umbilicus very wide and funnel-shaped, whorls small, cylindrical, and almost 
subearinate ; aperture small, almost circular, margins almost continuous, thin, and 
expanded. 
According to Dr. Servain, the Croatian specimens have been erroneously referred 
to H. erjaveci, and the Polish shells to H. striolata by various observers. 
Austro-Hungary—Agram, Croatia (Servain, l.c.). 
Russia—Ojcow, Poland (Westerlund, Palzearct Moll., 1889, p. 44). 
Var. umbrosella (Jousseaume ms. 1883) Servain. 
Helix umbrosella Servain, Ann. Malac., 1884, vol. i., p. 358. 
SHELL more depressed, umbilicus wider, aperture less oblique, less deflected, but 
relatively larger, and its margins stronger and more expanded. 
This form was discovered in 1883 by Dr. Jousseaume, who provisionally gave it 
in ms. the name it now bears. 
Austro-Hungary—Banks of the river Salzach, Salzburg (Servain, l.c.). 
Var. amela (Bourguignat ms. 1879) Servain. 
Helix amela Servain, Ann. Malac., 1884, vol. i., p. 360. 
SHELL more depressed but scarcely so large as var. @coscia, uinbilicus excessively 
dilated (4 mill. wide), whorls 6, subangular, very small and vermiform, slowly 
increasing in size and compactly coiled, the last not large, with a very slight deflec- 
tion at the aperture, which is of an oblong shape with a thin peristome uniformly 
expanded and almost continuous. 
This is said to be an extreme form of the var. @coscia, and is remarkable for its 
very narrow and closely coiled vermiform whorls. 
Austro-Hungary—Carniola (Westerlund, I.c.). 
VARIATION IN SIZE OF SHELL. 
Var. sciraia (Bourguignat ms. 1879) Servain. 
Helix sctrvaia Servain, Ann. Malac., 1884, vol. i., p. 339. 
SHELL larger than H. wmbrosa, with a more open umbilicus, and whorls more 
rapidly increasing in size, and remarkable for the slow and gradual deflection of the 
last whorl, the deflection originating half-a-whorl from the aperture, which is almost 
circular, the peristome is direct, and only slightly reflected basally. 
The shell figured as H. umbrosa by Rossmiissler in his Iconographie, fig. 424, to 
a certain extent represents this form in its size and contour. 
Austro-Hungary—Croatia. 
Var. minor Rossmiassler. 
SHELL smaller, paler, with a narrow umbilicus. 
This, according to Prof. Brusina, is the most common form in Croatia; it is 
smaller than the type, darker in colour, with a less reflected peristome, and said 
to serve as a passage to H. hispida. 
The var. minor Brusina, according to Dr. Servain, does not, however, appertain 
to H. umbrosa, but to the group of H. circinnata, and is the Helix mabara of 
Bourguignat. 
CONTINENTAL DISTRIBUTION. 
Austro-Hungary—Recorded by Gallenstein as plentiful in the garden of the 
Benedictine College, Klagenfurt, Carinthia; by Prof. Brusina from Styria, and 
from the banks of the Save and Una, Croatia ; and by Rossmassler from Tharand, 
Saxony, and from Gunzberg, Suabia. 
VARIATION IN COLOUR OF SHELL, 
Var. rubra T'aylor var. nov. 
SHELL of a ‘‘ beautiful reddish ”’ colour. 
Austro-Hungary—Recorded by Dr. L. Pfeiffer from the Monchberg, Salzburg.
