2 Crust. 
X. CRUSTACEA. 
series of papers on the homology of the appendages in the different 
groups of Crustacea , comparing them with those of other Arthropods, 
but, as he has written in Polish, it is not very easy to follow him. 
Sowinski (170) & (171) deals (in Russian) with the Malacostracous 
Crustacea of the Black Sea and Sea of Azof. 
Good descriptions of marine Decapod Crustacea of the Indian Ocean 
are given by Alcock (1), Anderson (8), and Henderson (82) ; of 
the Malay Archipelago by de Man (104) ; of Europe by Caullery (37) ; 
while Ratiibun (135) publishes a well illustrated monograph of the genus 
Callinectes. The Systematic of the group Lithodinea is dealt with in de- 
tail by Bouvieu (26), that of the Sergestulte by Hansen (80), who shows 
that very many of the so-called species of Sergestes are really larval forms. 
An excellent account of Pelagic deep-sea Schizopods is published by 
Chun (46, v), and Sars (157) has an important and well illustrated mono- 
graph on the Mysidce of the Caspian Sea. 
Bonnier (23) describes in detail and gives good figures of many now 
Cuinacea from the Gulf of Gascony, nearly doubling the number of 
species previously known in that group. The internal anatomy of the 
Isopoda is dealt with by Nemec (118) and Martynov (108), and a good 
many Terrestrial Isopoda are described in several papers by Dollfus ; 
while Sars (155) continues his descriptions and figures of the Norwegian 
Isopoda, and concludes (156) his important monograph on the Amphipoda 
of the Caspian Sea. 
The relationships of certain groups of the Amphipoda to one 
another is dealt with, but in Polish, by Garbowski (65), his views being 
illustrated by a genealogical tree. 
With regard to the Entomostraca , the most important works are those 
of Schmeil (160) on German freshwater Copepods, of Scott (T. & A.) 
on the British Copepods, of Karavview (91) on those of the Black Sea, 
unfortunately in Russian, and of Giesbrecht (71) on the Pelagic 
Copepods of the Red Sea, while those of the Gulf of Gascony are dealt 
with by Canu (35). Sars has a series of excellent papers on freshwater 
Eutomostruca from different localities, raised from dried mud (149)— (154). 
The monograph of the marine and freshwater Ostracodd of the 
N. Atlantic and N. W. Europe by Brady & Norman (28) is continued, 
and the Cgtheridce of Switzerland are monographed by Kaufmann (92). 
Richard (140) furnishes a monograph of the Cladocera, which, with its 
good bibliography, will probably be very useful. 
In addition to these monographs and other works dealing with the 
anatomy of the different groups concerned, some more special papers may 
be here referred to. The most important are those of Chun (46, vi), Gies- 
brecht (72), and Rosenstadt (144) on phosphorescent organs and eyes, 
and on the development of the eyes by Roule (148); those of Allen (4), 
Rath (134), and Betiie (20) on the central and peripheral nervous sys- 
tem of Decapods; and the sonse-organs of Crustacea , especially those of 
taste and smell, are made the starting-point for a discussion of thoso 
organs and their functions in general by Nagel (114). 
Several important memoirs on the development of Crustacea have 
appeared. Amongst these may be mentioned that on the embryonic 
development of Palcemon serratus by Roule (147, ii) ; of Gebia littoralis 
and of the Cumacea by Boutsciiinsky (in Russian, however) ; and of 
Asellus aquaticus by Roule (147, i). The embryonic development of 
Amphipods is dealt with, and the formation of organs in the marine 
and the freshwater species of Gammarus compared, by Rossykaia-Kojev- 
nikowa (146). Schimkewitsch (159) discusses that of parasitic Copepods, 
giving instances of gastrula formation both by emboly and epipoly, and 
Bigelow (21) describes the early development of aCirripede, showing the 
formation of a true gastrula stage there. The anatomy of the Nauglius
