HELIX CANTIANA AT QuEBEc.—Few accessions from abroad to 
our lists of land shells having lately been recorded, the discovery 
in Canada of a large colony of a foreign species, not previously 
nown to occur on this continent, is of more than ordinary in- 
terest. When at the ancient capital recently, in ascending the 
steps from Dufferin terrace to the citadel, I stopped to recover 
breath on a stage considerately provided for such purposes, at a 
point at about thirty feet from the summit of the glacis. From 
this resting place a path, trodden only by goats and equally sure- 
footed Quebec gamins, leads upward in a westerly direction 
along the steep and narrow slope between the south walls of the 
citadel and the almost perpendicular rock on which it stands. 
Noticing a small helix moving on the path, I passed under the 
guard-rail and ventured out upon it, not indeed wholly without 
fear, as there was danger, in case I slipped, of falling into Cham- 
plain street, four hundred feet below. The shell, which proved to 
be Helix rufescens Pennant, was found in abundance, in company 
with numerous Limax agrestis L., clustering around the roots 
and climbing the stems of a tall, rank weed, apparently a species 
of Ambrosia. An occasional specimen of a larger shell, which I 
Supposed to be immature Æ. hortensis, was also found at intervals 
along the path; and directly above where Montgomery fell, it oc- 
curred in considerable numbers in scattered clumps of grass 
which had obtained a foothold on the shaly cliff. Itseemed strange 
concentric line conspicuous on the body whorl of the English 
specimens of Æ. cantiana, and is somewhat smaller; but has e 
e 
y 
Specimens, if think it worth the trouble. I might add 
that it was a kan, moist evening when I found the shells.—
