Lake of Geneva. Six species of Axiodonta and one of TJnio are critically 
described by Brot in the paper mentioned above (p. 487), 
Transxjlvania. E. A. Bielz’s fauna of the land- and freshwater mollusca 
of Transylvania is distinguished by exact descriptions, careful indications of 
localities, sound general remarks concerning the geographical distribution, 
and practical hints for collecting these animals. The first edition, published 
in 18G3, was sold within a few years, which proves that the number of 
conchologists is increasing. The present second edition offers few altera- 
tions, which refer chiefly to the species of Limacidee and the subgeneric divi- 
sions of the Helicidce. Amalia margmata (Drap.), Limax transilvanicus (Hey- 
nemann), and Helix schmidtii (Ziegl.) are species of the second edition not 
mentioned in the first ; on the other hand, Limax variegatus and L. sil~ 
vaticus of the first edition ought to be erased. On the whole there are 155 
species, 120 of which are terrestrial, and only 35 fluviatile. The genus 
Clausilia alone is represented by 34 species, 12 of which, together with 5 
enumerated by the author under the genus Balea^ constitute the interesting 
group of the so-called Baleo-clausilice (Alopia, Adams) quite peculiar to Tran- 
sylvania, and chiefly occurring on Jurassic limestone. Some other more inter- 
esting species of this fauna are the following : — Haudebardia transylvanica 
(E. A. Bielz), Vitrina plicosa (E. A. Bielz), Hyalina natolica (Albers), Helix 
solaria^ triaxia, bidens, var. major, fusca (Mont,, British and also in some parts 
of France, but not yet found in Germany), H. bielzi (A. Schmidt, allied to H. 
coh'esiana), vicina (Rossm.), banatica, cetliiops (M. Bielz, an aberrant form of 
arbustoruni), faustina, tx'izona, lutescens, instabilis, Btdimimis reversalis (E. A. 
Bielz, the whorls of some specimens going to the left, of others to the right ; 
the same occurs in some species of Baleo-clausilia), Pupa biplicata and trun- 
catella, Planox'bis septemgyratus (Ziegl), Cyclostoma costidatum (Ziegl), Bi- 
^mscAe/^ (Paasch) of Sheppard, ventxicosa ofLeach and Gray], 
Lithoglyphus naticoides (Fer.), Neritjna transversalis (Ziegl), and Pisidium 
cuneatum (E. A. Bielz). Neither Helix nemoralis nor hortensis are found within 
Transylvania, they are represented by H. austriaca ; likewise several other 
speci,es rather generally distributed through Middle Europe are absent in 
this country ; such are, Ax'ion ater, Helix obvoluta, lapicida, cobresiana, rufes- 
cens, ericetorum, candidula, Balea perversa, Clausilia xiigx'icans, plicatida, par-
