the axis of the shell; but in his account of the present species 
in the ‘ Fauna Suecica’ he has stated that the whorls are painted 
longitudinally, evidently here speaking of the spiral (or trans- 
verse) fillets. This seeming contradiction no longer appears 
one, when we observe that in the former case he is speaking of 
the shell as a whole, in the latter of the whorls as a part only 
of the shell; thus the same line may be longitudinal in relation 
to the “testa,” and yet not so in relation to the “ anfractus.” 
A passage in his‘ Fauna Suecica’ (edit. 2, p. 531) explains 
this fully. He thus writes of the H. putris: “in omnibus 
strie minutissime anfractuum transverse, seu teste longi- 
tudinales.”

Of the shells in the Linnean cabinet the Helix nemoralis (as 
defined by Pfeiffer in his Monograph of the Helices) exclusively 
agrees with the description and figures of this species: hence 
the specimens may fairly be considered typical. Nevertheless, 
as many writers still persist in regarding the H. hortensis of 
Draparnaud as specifically distinct, and not a mere variety, it 
becomes requisite to determine (since both these shells are 
present: in the collection) for which of them the Linnean 
name should be reserved. The verbal definition in both the 
‘Systema’ and the ‘Fauna Suecica’ would include hortensis, 
and in one of the quoted figures (Lister, Conch. pl. 57, middle 
f. 54; not 58, as in the twelfth edition of the ‘Systema,’ for 
that drawing was meant for arbustorum) the apérture is repre- 
sented as pallid. The colouring of the mouth, however, is only 
mentioned in the ‘Museum,’ wherein the var. b seems the 
restricted nemoralis of modern writers, and the var. a, from the 
specification of its larger dimensions and of its greyer tint, 
seems rather to have been the vermiculata of Miiller, of which 
many individuals are present in the cabinet; and the far 
greater preponderance, in the synonymy, of delineations of the 
dark-mouthed snail, justifies authors in assigning to it more 
especially the name nemoralis. ~
