389, pis. xxi. & xxii. 10 terrestrial and 2 fresh- water species collected

Mauritius. Description of some new species, and critical notes concern- 
ing the occurrence, specific distinctness, and nomenclature of others, by

11 . Central and Eastern Asia. 
Hasrat Sultan Mountains, S.E. of Samarcand. 11 species of land-shells 
collected by Haberhauer, enumerated by H. Dohrn, JB. mal. Ges. ix. 
pp. 115-120. Besides some already known from Turkistan by the col- 
lections of the late P. A. Fedtschenko, there are some already known 
from Northern Syria and Ilindostan, and 1 new Zonites. 
Central Asia. 24 land and 17 fresh- water shells, collected by A. Hegel, 
N. M. Przewalski, and Potanin, on both slopes of the Tianshan Moun- 
tains and in Eastern Mongolia, 3 collected by Bichthofen in the Loss of 
China, and some new additions to the fauna of Turkistan and Khiva are 
enumerated and described by E. v. Martens in Mem. Ac. Petersb. xxx., 
No. 11, 65 pp. 5 pis. Varieties of Limncea stagnalis and auricularia from 
the River Tarim, and L. plicatula (Bens.), var. n., from Lake Kukunor, 
may be mentioned here. The species not before figured will be men- 
tioned in the special part. A list of all known land and fresh- water shells 
of Central Asia, from the Altai to Ladak, and Kokand to the confines of 
China proper, is given, pp. 49 & 50, with special analytic tables of the 
species of Helix , pp. 19 & 20, and of Bulirninus, p. 27. Generally, the 
Molluscau fauna of Central Asia is rich in Helix belonging or near to the 
group Fruticicola , in Bulirninus , Succinea , and Limncea ; it agrees in these 
and other features with the general paleearctic fauna, chiefly the more 
northern circumpolar part of it, and wants a number of genera charac- 
teristic of South Europe, and especially the genus Clausilia. 
Preliminary notes on a collection made by A. Kuschakewitz in the- 
mountainous regions from the Lakes Alakul and Issikul to the Pamir 
table-land, with some new species, by E. v. Martens, SB. nat. Fr. 1882, 
pp. 103-107.
