8 Crust. 
CltUSTACEA. 
phemidce 1, Leptodoridce 1. Forty- two of them are also British species. 
Most of the species are illustrated by woodcuts, representing either the 
whole animal, or more often some characteristic parts of it. The new 
species will be mentioned below. Some general remarks concerning their 
occurrence and manner of life, as well as their geographical distribution, 
are given at the end of the paper. The recorded species of Bohemia are 
more thuu those kuowu in any other country, but there is not much dif- 
ference in the prevailing genera and species between that part of Europe 
and Russia, Sweden, Denmark, Germany, or England. 
The Cyclopidce living in Holland are enumerated by P. P. C. Hoek, 
Tijdschr. Nederl. dierk. Ver. iii. [187G], pp. 1-37, pis. i.-v., and Niederl. 
Arch. Zool. iii. [187G] pp. 127-1(53, pis. vii.-ix. In the former, two species 
living in cisterns, Cyclops hrevicaudatas (Claus) and hicuspidutus (Claus), 
are fully described. 
Palaimon serratus (Penn.) abundant in the rivers Tejo and Sado, 
Astacus fluviatilis not mentioned as Portuguese ; Brito Capello, J. Sci. 
Lisb. vi. p. 79. 
Fauna of Lakes. 
F. A. Fouel makes some general remarks on the subdivisions and 
origin of the fauna of the lakes in Switzerland, distinguishing (1) the 
littoral fauna, (2) the pelagic near the surface of the open water, and (3) 
the fauna of the depths. A. Weismann points out that the pelagic 
Crustacea of the lakes have eyes which are adapted to a small degree of 
light, and therefore keep during the daytime at a great depth, and at 
night or twilight near the surface. Ber. Vers. Naturf. (Munich) 1877, 
pp. 172 & 173. See also Niphargus (Gammaridcv) in the special part. 
Lake of Constance. Notes on its Crustacea^ chiefly Entomostraca near 
the surface far from the banks and those living in deep water, by A. 
Weismann in his pamphlet, “ Das Thierleben im Bodensee,’* sep. print 
from “ Schriften zur Geschichte des Bodensees,” pt. vii. pp. 11-17, with 
figures of some remarkable species. 
Note on some Cladocera found in the lake of Gmunden in Austria by 
Claus, Denk. Ak. Wien, xxxvii. p. 137. 
Foreign Land or Freshwater Crustacea. 
Species of crayfish in Indiana; Bundy, P. Ac. Philad. 1877, pp. 171-173, 
Several new species of Oniscidce from South America and Eastern Asia, 
freshwater Falcemon from South America, and freshwater Cymothoidce 
from North eastern Asia described by Mieus, P Z. S 1877, pp. GG0-G7G. 
Falcemon ohionis, sp. n., in Ohio river, see infra. 
Notes on Australian Cladocera by SciiajDLER, SB. nat. Fr. 1877, 
pp. 11-14; one, Simocejdialus vetulus (Miill.), is identical with a common 
European species.
