In Prof. Huxley’s manual of the anatomy of invertebrated animals, 
the structure of the genera Limulus^ Chondr acanthus^ Apus, Lepas^ 
Astacus, Carcimis, Mysis^ Amphithoe, Cymothoa, and Squilla are described 
as examples of the chief divisions of the Crustacea. 
In the “ Handbuch der Zoologie,” edited by Dr. G. VON Hayek at 
Vienna, the first part of the second volume, published at the close of 
1877, discusses the Crustacea] a large number of woodcuts, copied from 
the principal authors, aid the student considerably in understanding the 
subject. 
Anatomy and Embryology, 
W. V. Nathusius, in the work cited above {Mollusca^ p. 5), pp. 33-45, 
pi. ii. fig. 15, treats also of the microscopical structure of the shield 
(carapace) of the Crustacea^ chiefly of Platycarcinus pagurus^ pi. ii. 
fig. 15, pi. iii. figs. 16 & 17 b, Flomarus vulgaris^ pi. iii. figs. 17 a & 19, 
pi. iv. fig. 20 a, As tocifs fluviatilis, pi. iv. fig. 20 b, and endeavours to 
prove that it is not cuticular or formed by simple secretion, but com- 
posed of fibrillas and really organized, yet not cellular. 
Crustaceorubrin, giving an intense scarlet colouring to various Crustacea 
in deep water, such as Gnatheuphausia, Petalophthalmus, several Peneids 
and Caridids, and probably also Paiidarus ; spectral band in all the same.

The heart of the Crustacea^ with regard to its structure and 
movements, is the subject of a paper by J. Dogiel, Arch. Phys. 1877, 
pp. 401-408, with a plate. Ganglionous cells in the heart of the common 
crayfish described by E. Berger, SB. Ak. Wien, Ixxiv. pp. 422-424, with 
a plate. 
The muscles of the common crayfish are described by G. Asber in a 
separate treatise ; “Die Muskulatur des Flusskrebses.” Zurich ; 1877. 
The stomach of the same, and of the lobster and Carcinus mcenas^ 
described by T. J. Parker, J. Anat. Phys. xi. [1876] pp. 54-60, pi. ii. 
G. F. Tursini has made several experiments concerning the power of 
re-absorption in the intestine of some Decapod Crustacea^ as Maia^ 
Dromia, Scyllarus, and Palinurus, and comes to the result that solid 
particles of coal and carmine find their way through the chitinous mem-
