HELIX HORTENSIS. 351 
: VARIATIONS IN BANDING OF SHELL. 
Var. fasciata Moquin-l'andon. 
Helix hortensis vars. untfasciata, bifasciata, trifasciata, guatuorfasciala, quingue- 
Sasciata, aud interrupta (Picara, Moll. Somme, 1840, p. 215-217). 
Helix hortensts vars. /asciata, coalita, interrupta, puncteda (Mcquin-Tandon, Hist. 
Moll. France, 1855, p. 167). 
SHELL with dark spiral banding, which may be continuous, interrupted, or 
coalesced, and includes all spirally fasciate forms. The name was first applied by 
Menke (Syn. Moll., 1830) without description. 
The var. faseciata Mogq., s.s., is applied only to shells with distinet bands, and 
other than five in number. The var. fasciata of Boyeott and Bowell (op. cit ) is 
restricted to shells with a white or yellow ground, but is unrestricted in its number 
of bands. , 
The sub-var. interrupta of Picard and Moquin-Tandon has the spiral fasciation 
interrupted. 
The sub-var. punetella Mog. shows the bands still further disintegrated and 
broken up into spots. 
The sub-var. eoalita Moq. has the spiral banding more or less fused together 
or coalesced, forming one or more broad combined bands. : 
The five-banded form is the quinquefasciata of Picard, the guinguevittata of 
Mogquin-Tandon. 
The sub-var. quatuorfasciata Picard possesses four apparent bands, the most 
interesting arrangement in this group being 1(23)45. 
The sub-var. trifaseciata Picard shows only three apparent bands, a striking 
example being 1(234)5. 
The sub-var. bifaseiata Picard embraces the shells showing only two bands, 
whether these be simple or composite, the two most remarkable instanced by the 
author being (12)300 and 1(2345). 
The sub-var. unifaseiata Pic. embraces the shells showing a single hand only. 
The sub-vars. sexfaseciata Picard and septemfasciata Picard, which show 
six and seven bands respectively, are, as in H. nemoralis, due to the dismember- 
ment of one or more of the five normal bands. 
The sub-var. infrafaseiata of Cockerell indicates those shells with the bands 
quite deficient above the periphery, and only bearing the most basal zone beneath ; 
it is represented by the formula 00005 ; and is identical with the sub-vars. morletia 
of Locard and barrvaudia of Moquin-Tandon. 
The var. fasciata and its many modifications are distributed throughout the 
range of the species, and a citation of the records of the more ordinary variations 
would fill many pages; therefore, apart from the American distribution, only the 
localities of some of the more uncommon forms are enumerated, 
ENGLAND.
