Sea shells from the eastern part of the Mediterranean, from the Black 
and Caspian Seas, collected by G. Fritsch, with general remarks about 
the fauna of those seas, that of the Black Sea having the same relation 
to the Mediterranean as the Baltic to the Northern Atlantic ; v. Mar- 
tens, SB. nat. Fr. 1877, pp. 197-200. 
Caspian Sea. O. A. Grimm has continued his successful researches on 
its fauna, describing several new species, and stating the occurrence of 
others at various depths. The majority of the shells hitherto known are 
from a depth limited to 140 feet, but Cardium catillus reaches from 161 
to 630 feet, Dreyssena rostriformis 161 to 910 feet, Hydrohia caspia to a 
depth of 1050 feet. Kaspinskoe more i ego fauna, pt. 2, with 3 pis.,

Lake Aral. Note on its 3follusca by W. D. Alenitzyn, Meeting of 
Russian naturalists at Warsaw, September, 1876 ; Z. wiss. Zool. xxviii. 
pp. 406 & 407. The author distinguishes two zones— th6 upper, which is 
agitated by wind, and the under, beginning at a depth of 140 feet, which 
is always tranquil — and points out how the Mollusca of the upper zone 
are specially enabled to resist the movement of the waves, by the pre- 
sence of a byssus, by a very large foot, by burrowing in the sand, &c. 
The species are the same as in the Caspian Sea.
