Six species of Cyclostoma (see below), 16 of Pomatias^ and 3 of Acme^ 
living in France, are enumerated by J. Mabille, K. Z. (3) iii. pp. 145-156. 
C. Lallemant & Gr. Servain have published a “Catalogue des 
Mollusques terrestres et fluviatiles observes aux environs de Faulgonne, 
Dep. Aisne^ Paris : 1869, 8vo, 53 pp. [not before seen by the Recorder] ; 
it contains 83 terrestrial species, of which one is new. Helix ser'Daini, and 
one only acclimatized, H. lauta (Lowe), and 57 freshwater-shells (one 
new). The author follows Bourguignat & Mabille in minute distinction 
of species. 
2 . t^qutheryi Europe and Northern Africa, 
W. Kobelt continues the late Rossmassler’s “ Iconographie ” (in- 
tended to illustrate the land- and freshwater-shells of Europe and the 
adjoining parts of Asia and Africa), interrupted for many years. 
Several species of Helix^ of the groups Pentatcenia and Campy lma>, are 
figured, and will be noticed hereafter. 
Forty-seven species observed in the Val di Caffaro^ Brescia, by G. B. 
Adami, Bull. mal. Ital. (2) i. p. 93. 
Fifty-seven species' collected in the Valley of the Serchio and the Apuan 
Alps by C. DE Stefani are enumerated, tom. cit. p. 35. 
Some notes on Mollusks found at Yiareggio, Massarose, and Camajore, 
Tuscany, by R. del Prete, tom. cit. p. 25. 
The geographical distribution of terrestrial Mollusks in Sicily is dis- 
cussed by W. Kobelt j there are 80 distinct species of the genus Helix 
in its old sense, and among them 44 species, or 55 per cent., peculiar to 
that island, most of them found only near the western extremity and the 
adjacent islets. JB. mal. Ges. ii. pp. 7-25. 
J. G. Hidalgo has commenced a treatise on the land Mollusks of 
Spain and Portugal [supr^, p. 132] ; the parts already published contain 
notes on the malacological books and on the naturalists and collectors 
who have contributed to the knowledge of that fauna, with an alpha- 
betical list of 336 species, distributed in 26 genera. The plates contain 
263 figures of shells of the genus Helix, There are some notes on them 
by Pfeiffer in Mal. Blatt. xxii. p. 210. 
Pyrenees, The hypsometrical distribution of the land-shells in the 
Central Pyrenean Mountains is discussed by P. Fischer, who distinguishes 
five regions, and states that an elevation of about 2500 metres is the 
limit for the occurrence of land-shells, and that of 1000 metres for 
many species of freshwater-shells. 
Portugal, Some notes on land- and freshwater-shells by A. Luso da 
Silva, J. Sc. Lisb. iv. pp. 62-65 {Pupa, Vertigo, Anglica., Carychium'), 
and pp. 241-246 (two new species of slugs, appearance of Dreissena 
fluviatilis \_polymorpha'] in Portugal, Paludina fasciata). 
Morocco. The shells collected near Mogador by Von Fritsch & Rein in 
1872 are compared with those collected by Lowe in 1859 (P. L. S., 
1860) by E. v. Martens, JB. mal. Ges. ii. pp. 95-102. Forty species 
(some new) collected near Tangiers by Bleicher are described by 
A. Paladilhe, with a concluding note on all species known from
