R. Etheridge describes some peculiar bodies, which may be the oper- 
cula of Gastropods, from the Carboniferous Limestone, with notes on 
some Silurian opercula. Ann. N. H. (5) vii. pp. 25-31, pi. ii. 
The existence of the genus Helix^ subg. Gonosioma and Patula, in the 
cretaceous beds of India, proved by the late Dr. Stoliczka ; Nevill, 
J. A.S. B. 1. pt. 2, p. 128. 
39 species of land shells found in the pleistocene beds near Weimar, of 
which the following no longer survive in that country : Zonites verticillusi 
Helix tonnensis (Saudb.), austriaca, Cochlicopa columna, Pupa doliolunv 
Clausilia filograna ; Helix ericetorurn, candidula^ and nemoralis are want- 
ing in the pleistocene beds, though chiefly common at present. O. Schmidt,

18 terrestrial and 21 freshwater shells from limestone-tufa at Grenssen, 
near Sondershausen, Thuringia, all still living [also Helix nilssoniana 
(Beck), which the author says is extinct], enumerated by P. Hesse, 
Nachr. mal. Ges. 1881, pp. 6-8. 
H. V. Ihering enumerates the diluvial land and fresh- water shells 
found by him in the ‘ Friinkischo Schweiz’ (Northern Bavaria) ; 18 are 
no longer found alive in the same country, and among them are some 
which belong to a more southern or rather more Alpine fauna, as Zonites 
verticillus^ Pupa pagodula, and Clausilia filograna ; on the contrary, two 
species of the subgenus Xerophila, Buliminus detritus^ and Unio hatavus 
are now found alive, and are wanting in the diluvial beds. Mal. Bl. (2) 
iii. pp. 73-77. 
29 terrestrial and 5 fresh- water species from the Loss, in the Rheingau 
(middle part of the Rhine valley), of which 2 are extinct, and 5 no longer

pp. 9-11. 
The quaternary beds of fresh-water clay near Lyons contain 46 species 
of land snails, 24 fresh-water snails and 7 bivalves, of which only 1, Lim- 
ncea gerlandiana, is extinct, and some terrestrial species no longer live in 
the same country, though existing in more northern or alpine regions.

Postpliocene land and fresh-water shells from peat at Polada, near 
Lonato, province of Brescia, by G. B. Adami, Bull. Soc. mal. Ital. vii. 
pp. 188-202 ; the majority are species still living in the same country, 
several others seem to indicate a somewhat cooler climate ; Anodonta and 
Unio are entirely absent ; a new variety of Valvata alpestris and a new 
Pisidium are not known olsowhere. 
A list of species found in the pliocene beds of Tuscany, which are still 
living in the Mediterranean Sea, is given by Dante-Patanelli, Bull. 
Soc. mal. Ital. vii. pp. 63-68. 
51 species of Mollusca from the post-tertiary alluvial tin deposits of
