Croatiai Brubina, in his pamphlet noticed above (p. 487), enumerates a 
large number of titles of books rofening particularly to the malacology of 
several provinces'of Austria, and proceeds to give a list of 175 species, among 
which 0 MclanidcOy 6 species of Neritina y 4 of Lithoglyphm, 1 Amnicola and 
1 Paludinellay 8 of true ZoniteSy G of Ilelicella [Ilyalina^ 30 of Clausiliqy 48 
of Ilelixy 3 of Pomatiaa. Decidedly southern forms are Stcnogyra decoUatay 
Olandina algiray Helix olivieri, pyramidatay cinctay &c. Helix nemoralisy hor- 
tensis, and austriaca are found within this province. H. ohvolutay very com- 
mon in Southern Germany, is not mentioned, but H. holoserica and personata. 
Species peculiar to Croatia are\HcZ*.r ccxi'ulans stenornphala (Menke), 
Zonitea croaticua (Partsch), &c. 
Brittany. Tasl-6's catalogue of the mollusks of the department of Mor- 
bihan, Vannes, 1867-68^ contains, among others, Arion flavuSy Limax arhoruniy 
and company oi, Milax sowerhyi, Testacella maugeiy and hisulcata (the occurrence 
of the last is doubted by P. Fischer), Zonitea suhglaher, Helix ptilotay Vertigo 
loroisianaj Physa (these 4 species described by Bourguignat as new), 
Succinea dehilisj and Ancylua atrictua. 
Soidh-weatei'n coast of France . — The intralittoral ” region (that is to say, 
a region, consisting of sand-downs and boggy marshes, between the left bank 
of the Garonne and the sea, as far as la Baise,” which was almost unknown 
and inaccessible before the establishment of a railway) has been repeatedly 
explored by J. B. Gabbies. The list of mollusks observed by him contains 
35 land-snails and slugs, two submarine species (Auricula \_Alexui] myosotis 
and bidentata)y 19 freshwater gastropods, and 14 freshwater bivalves j some 
species are new. Helix variabilis, including maritima (Drap.), H.pisanUy H, 
revelatUf and Bulimua acutus are the most characteristic species ; the two latter 
are almost entirely absent on the right side of the Garonne, which is a lime- 
stone soil. On the other hand, Helix aspcrsa follows in the intralittoral region 
the railway-stations where limestone for buildings is found, and lives scarcely 
on merely siliceous ground. The translucent species of land-snails, as Zonitea 
[Hyalina'] and Succinea, are numerous in species j and even of Helix aapersa 
and^asawa there are translucent varieties. Two species of Testacella occur — 
T, haliotidea, var. scutulum, and T. maugei j the latter, together with Succinea 
longiscuta and Helix revelata, are examples of the Lusitanian maritime cha- 
racter of the fauna. On the other hand, it is strange to find Helix aculeata 
among decaying fir-trees and moss on the downs ; one Clausilia (nigricans, 
Pult.), one Pupa (umbilicata, Drap.), and two species of Vertigo have been 
found. Among the freshwater shells, Amphipeplea glutinosa, Limncea glabra, 
and a new Hydrobia may be mentioned. 
Pyrenees. 0. Debeaux has made new malacological researches in the 
valley of Bareges, and raised the number of 32 species, enumerated in the year 
1863 by Saulcy, to 64, among which the genera Limax, Vitrina, Zua, and Hy- 
drobia. Arion albus occurs with A. rufus and ater, but is only of half the usual 
size J Vitrina clmigata (Drap.) and V. pyrcnaica (F6r.) in the lower regions of 
the valley j Helix nemoralia in the woods of firs to a height of 1800 metres, 
smaller than in the lower regions; 11, ericctorum ascends nearly to the same 
height, and is there also of smaller size and without bands, the higher 
region offering less supply of limestone for their shells. H, nubigena and
