HELIX PISANA. 395 
Dublin—Mr. A. R. Hogan in 1854 described the species as well-marked and 
plentiful on the sea coast at Rush, where it is still abundant. Dr. Farran about 
the same time discovered it at Knockangin, about 1} miles north of Balbriggan, and 
also placed on record his apparently unsuccessful attempts to acclimatize the species 
at Portmarnock, and at Feltrim near Malahide. 
There re specimens in the National Museum, Dublin, labelled ‘* Drumeondra,” 
but Mr. Stelfox informs me that the species does not seem to live there, and these 
specimens may have been taken with the sand which is frequently carted for build- 
ing purposes from the localities where H. ) isana naturally exists. 
Kildare—Mr. L. E. Adams (Manual, p. 82) quotes Kildare as one of the counties 
for this species, but further information has been unobtainable. 
Wexford—I)r. Farran recorded in 1854 that Mr. Butler Bryan distributed a 
number of living Dublin specimens on the demesne at Ferns, but though the 
experiment apparently failed, he purposed again attempting to naturalise the species 
there but on a more extensive scale. 
Queen’s Co.—Specimens are in the ‘‘Warren Collection” of the National Museum, 
lbublin, labelled ‘* La Bergerie, Rev. B. J. Clarke,” but Mr. Clarke’s note books, 
which are preserved at the Museum, contain no mention of the occurrence of this 
species at La Bergerie, and only refer to the known localities on the Dublin coast. 
Galway W.—Dr. Farran in 1854 stated that the late Mr. MecAlla had informed 
him that he had seen the shell at Bunowen, in Connemara, West Galway, but there 
has been no confirmation of the record, although the district has been often carefully 
examined, but Mr. Stelfox informs me that a large form of H. virgata is found there, 
which might easily on casual inspection be mistaken for H. pisana. 
Kerry—Mr. Andrews reported in 1854 that on the promontory of Iveragh he had 
found a number of H. cingenda, firmly attached by a kind of deposit or incrusta- 
tion to the leaves of the yellow water Iris, in company with Suecinea putris; but 
this assumed discovery has also never been confirmed. 
GERMANY. 
A specimen exists in the collection of Mr. G. K. Gude, labelled ‘* Heidelberg,” 
hut the loeality is certainly erroneous as indicating a natural habitat of the species. 
BELGIUM. 
MM. Colbeau and Lanszweert in 1868 attempted to natnralize the species at 
Ostend hy distributing over the dunes a number of specimens from Alviers. 
FRANCE. 
Almost restricted in its distribution to the maritime departments, but extends 
many leagues inland from the coast, although its occurrence in the Vosges, chronicled 
by M. Puton, is erroneous. It is recorded from Alpes Maritimes, Aude Basses 
Pyrénées, Bouches du Rhone, Calvados, Charente Inferieure, Cotes du Nord, linis- 
tere, Gard, Gers, Gironde. Haute Garonne, Haute Pyrénées, Hérault, Ille-et-Vilaine, 
Indre-et-Loire, Landes, Loire Inférieure, Manche, Morbihan, Pyrénées Orientales, 
Rhone, Var, Vaucluse, Vendée, Vienne, and the Island of Corsica. 
In addition, it was recorded in 1882 from Lyons by M. Locard, who was of opinion 
that the species had migrated with certain plants from the Mediterranean coast. 
M. Mabille has also described its introduction in 1870 to the banks of the River 
Marne at Charenton near Paris, as being due to a friend who, on his return home 
from travelling in the south of France, brought with him a large basketful of these 
snails for table use, but falling ill, the nurse, who attributed his malady to the 
snails, emptied the basket containing them upon the river bank, by the omnibus 
depot, where the environment being favourable, they prospered, but, according to 
Dr. Germain, have gradually become modified, as though at first all were fine, strong 
and distinetly banded shells, the great majority are now, though still of good size, 
of a delicate texture and a pure subtransparent white. ‘he area inhabited at first 
extended between the steamboat landing at the Bridge of Charenton and the mill 
at Alfort to a distance of 600 or 700 yards down the river, but owing to the crowds 
of Sunday excursionists who now regularly frequent and promenade the banks of 
the river, trampling upon the vegetation, and otherwise rendering the locality un- 
suitable for these mollusks, the colony lias been compelled to gradually migrate 
further and further down the river banks, and are now living under less favourable 
conditions and therefore, much less common than formerly. 
M. Danutzeuherg also possesses specimens from the Seine-et-Oise, labelled ‘Rueil, 
near Paris, 1902,’ which were procured from a colony artificially established there 
some time before.
