of rarfe or local species of mollusks in this kingdom, as well as in some parts 
of Bavaria and the Tyrol ; he also states the result of experiments as to the 
numerical proportions of small shells deposited on hanks of rivers. 
Switzerland. Helix pulchella is found on Mt. St. Bernard at an elevation of 
9500 ft., and Vitrina pellucida on the Riffelberg at 9000 ft., by RofpiAen, 
Ann. Mai. Belg. v. pp. xvii & xviii. A list of 16 spp. found in Switzerland 
is given by Craven, ibid. pp. lii-liv. 
Belgium. Accounts of land and freshwater Mollusca found in various 
Belgian localities are to be found nearly on every page of the Annals of the 
Malacological Society of Belgium. Bulimus astierianus (Diipuy) has been 
found at Namur (p. 45), and Physa acuta (Drap.) in different localities 
(pp. 19, 25, and xvii). II. aspersa (Miill.) appears to be limited to small 
areas, where it lives in considerable numbers, near human habitations, but 
never in deserted mountainous regions (p. 20). 
2. Southern Europe. 
. Croatia. Mollendorf (Nachr. malak. Ges. iii. 1871, pp. 20-29, 40-43, 
62-64) compares and translates rather fully Brusina’s publications on the 
malacological fauna of this province {cf. Zool. Rec. vii. p. 108), which ap- 
pears to contain 124 terrestrial and 45 freshwater spp. 
Selavonia. Several notes concerning the land and freshwater shells of this 
country are given by the same author, ibid. pp. 61 & 62. 
Bosnia. The same author publishes his personal observations on the mala- 
cological fauna of Bosnia, with a list of 46 spp., including a new Campylcea^ 
ibid. pp. 65-73. 
Kuster, in the commencement of an account of the land and freshwater 
Mollusca of Trieste and Dalmatia, discusses Bulimus, Cionella, and Pupa. 
Ber. Ges. Bamb. ix. pp. 91-94. 
Lombardy. A list of the known species of land and freshwater Mollusca 
of Lombardy, with synonyms and a few critical remarks, is given by A. & 
G. B. Villa, Bull. Malac. iv. pp. 81-96. 
Pyrenees. 25 species found in the vicinity of Ax (Ariege) are enumerated, 
and the habits of some of them noted, by Noulet in ^Mollusques d’environs 
d’Ax ’ (extr. in J. de Conch, xviii. p. 370). 
Hidalgo^s ^ Hojas Malacologicas ^ contain various lists written 
partly by himself, partly by Zapater and Macho, of terrestrial 
Mollusca collected in Murcia, Valencia, Galicia, Old Castile, 
and Portugal (pp. 5-32) ; also an alphabetical list of concholo- 
gical authors, with a special account of the slugs and land-shells 
mentioned by them as occurring in Spain or Portugal, pp. 81- 
184' (not yet finished), by the author. 
Azores. Tristram’s account of the mollusks adds no new species to those 
published in 1860 by Morelet, though confirming some of the latter. 
3. Western Asia, 
. Siberia. The Recorder has given a list of land and freshwater shells col- 
lected by Ehrenberg during his voyage to Siberia and the Altai with Hum- 
boldt in 1829. Those of the eastern slope of the Ural and the plains of Siberia 
are European ; in the large rivers of western Siberia no Unio has been found ;
