SHELL pale transparent yellow, with opaque straw 
coloured marblings, with a hardly apparent pale band

The sub-var. luteozonata Taylor sub-var. nov. 
differs from var. luteofasciata in having a ground colour 
as in the typical form (see Monogr., pl. xxxiv., f. 14). 
Usually the pale band oceupies the position of the 
dark supraperipheral band, but Hartmann figures a ee eee ee ee

Fic. 503.—Helix arbustorum var. trifasciata Taylor, Steinach, Switzerland (after Hartmann), 
Herr Clessin has recorded five specimens in his collection, which although 
regarding as possible hybrids with Helix nemoralis, he refers to this species. They 
are of a rich yellow colour, and possess the pentateniate banding, the formule 
being 12345, (12)345, (12)305, 123455, and 12345555. Dr. Hartmann has also inei- 
dentally alluded to a five-banded variety. 
The sub-var. bifasciata is described as ‘resembling the type, but having two 
bands, one normally placed, the other midway between it and the suture” (see 
Monogr., pl. xxxiv., ff. 13 and 15).
