442 HELICIGONA ARBUSTORUM. 
All bifasciate shells, whatever the position of the banding, are, however, included 
under this term until the range of band variation of the species is better known, and 
a formula devised to indicate their relative positions ; and this applies equally to the 
vars. trifasciata, tetrafasciata, and quinquefasciata. 
The sub-var. trifaseiata may be described as possessing three dark spiral bands. 
The sub-var. tetrafaseiata has four dark revolving bands. 
The sub-var. quinquefasciata has five dark revolving bands. 
ENGLAND. 
Dorset—A small variety, with three brown bands round the last whorl (sub-var. 
trifasciata) is recorded from Stoke Wake Hill, Houghton Wood, by Mr. J. C. 
Mansel-Pleydell (Moll. Dorset, 1899, p. 12). 
Northampton —A bifasciate shell with bands placed approximately as in hands 
3 and 4 of the pentatieniate formula, found at Kettering by Mr. C. E. Wright. 
York N.W.—Sub-var. bifasciata Kew, on roadside near the stepping-stones, 
Aysgarth, May 1903 ! F. W. Wilson (see Monogr., pl. xxxiv., f. 15). 
York S.E.—One bifasciate specimen with bands occupying approximately the 
positions of bands 3 and 4 of the pentatseniate formula, found by Mr. J. F. 
Musham at Barlby Bank near Selby ! (see Monogr., pl. xxxiv., f. 138). 
Durham—A specimen from Barnard Castle showing a fine but distinet additional 
band, occupying approximately the position of band 2 of the pentatzeniate formula! 
is in the Edinburgh Museum (Rimmer Coll.). 
CONTINENTAL DISTRIBUTION, 
Switzerland-—Dr. Hartmann figures an immature specimen with a pale yellow 
ground and three dark red-brown bands on the upper side (var. frifasciata) from 
Steinach, Canton St. Gall. 
A two-banded example is figured by the same author with bands placed as in 
the var. bifasciata Kew, from Gams, near Werdenberg, Canton St. Gall. 
A four-banded shell (var. fetrafasciata) is also figured from Schiinnis, St. Gall; 
it is not full grown, and is described as thin shelled, with its bands arranged as in 
Helix hortensis, ete., but the line between the fourth and fifth band is stated as 
indicated too strongly by the artist. 
Var. cineta Taylor. 
Helix arbustorum vy. pallida Taylor, Journ. Conch., 1881, vol. iii., p. 250 (not Westld.). 
SHELL of a yellowish ground tint, with a distinct and dark supra-peripheral band 
(see Monogr., pl. xxxiv., f. 4). 
The name pallida bestowed by me upon this variety thirty-three years ago, was 
subsequently ascertained to have been used by Dr. Westerlund to indicate a form 
of the var. favescens, so that a new name, eineta, is proposed to distinguish the 
present form. 
The var. cincta though widely distributed throughout the range of the species is 
not an abundant form.
