5 Crust. 
CRUSTACEA. 
Anatomy and Physiology. 
A, Wkzesniowski publishes some observations upon the skin aud 
adipose body (Fettkorper), the muscular and nervous systems, the sensi- 
tive bristles (which he regards chiefly as auditory organs), and the so- 
called ‘ calceoli,’ which occur also on the upper antennse and in females, 
and are regarded by him as olfactory, on the intestinal tract and its appen- 
dages, the antennal and testal glands, the heart, and the circulation in 
the Amphipods. Zool. Anz. ii. pp. 447-460, 465-491, 487-491, 511-615, 
536-540, 564-669. 
1 . Nervous and Muscular Systems. 
Note on the intimate structure and functions of the central nervous 
system of the Decapoda by E. Yung, C. R. Ixxxviii. pp. 240 & 347, Rev. 
lut. Sci. iii. p. 160; abstract in J. R. Micr. Soc. ii. pp. 419, 420, & 872 
[c/, Zool. Rec. XV. Crust, p. 5]. Experiments on the effect of Curare, 
fetrychnine, Atropine, Digitaline, and Nicotine on the Crustacea ; id. 
C. R. Ixxxix. pp. 183 & 184. This author also discusses the structure and 
functions of the nervous system of the Decapoda in Arch. Z. exper. 1879, 
and gives an abstract, with additions, in Arch. Sci. Nat. (3) ii. pp. 137-174. 
Unlike the brain of Vertehrata^ that of Crustaceans is sensible on all 
sides ; and it is distinctly the central co-ordinator of all movements.

p. 340) ; J. R. Micr. Soc. ii. pp. 422 & 423. 
Notes on the muscular and nervous systems of the Amphipods by A. 
Wrzesniowski, supra.

dichaudi (Aud. & Edw.) described and flgured ; A. S. Packard, Jr.,

Note on the nervous system of Cyclops by M. Hartog, Rep. Br. Assoc- 
(Sheffield) 1879, p. 376. 
Experiments on the physiology of the musscles and nerves in the lobster 
by L. Fri^dericq & Vandevelde ; they come to the conclusion that it 
agrees very much with that of the frog, only in the lobster the motor 
excitation travels much more slowly along the nerves (6 metres a second 
in the lobster, 27 metres in the frog). Bull. Ac. Belg. xlvii. pp. 477 & 
771-797.

muscles of the pincers of the Crayfish; id. 1. c. p. 1272. Abstracts of 
both papers in J. R. Micr. Soc. ii. pp. 562 & 873.
