ticularly interesting from the curious observations recorded on what 
we may call the terrestrial life of Fishes. The list of Fishes, drawn 
up principally by Dr. Giinther, and the remarks of Professor Huxley 
and Dr. Gray on the richness of the Fish-fauna of the Ceylonese 
seas, and its comparison with that of other regions, are also exceed- 
ingly valuable and suggestive. With the invertebrate animals Sir 
James Tennent seems to be less familiar; but even upon these we 
find many interesting observations, and each chapter is furnished, by 
way of appendix, with a list of the species of the group treated of, 
known to inhabit Ceylon. These lists, although confessedly imper- 
fect, will be, even as they stand, of great advantage to the student of 
zoological geography, whilst to those who may hereafter take up the 
investigation of the Natural History of Ceylon they will afford a 
most valuable aid. 
A History of British Sessile-eyed Crustacea. By C. Spencp Bare, 
F.L.S., and J. O. Wesrwoopn, M.A., F.L.S. &e. 8vo. London :. 
Van Voorst, 1861. Parts 1-3. 
Of two great sections of the class Crustacea the British species have 
already been admirably elucidated—the Podophthalmous forms by 
Professor Bell, and the Entomostraca by Dr. Baird. The abnormal 
forms constituting the group of Cirripeds, which may perhaps with 
some justice be ranked among the latter, have also received their due 
share of attention in Mr. Darwin’s classical work published by the 
Ray Society ; but there still remains a vast number of species, form- 
ing the group Edriophthalma of Latreille, to the arrangement and dis- 
crimination of which the British naturalist possesses no other guide 
than is afforded by Mr. Spence Bate’s ‘Synopsis ”’ published in this 
Journal (February 1857), and Mr. White’s excellent little ‘ Popular 
History of British Crustacea.’ Under these circumstances we wel- 
come with no common interest the appearance of the work of which 
the first three parts are now before us, in which Mr. Spence Bate, 
whose acquaintance with his subject no one can doubt, has called to his 
aid the artistic talents and great general knowledge of the Articulata 
possessed by the distinguished Hope Professor at Oxford; and, from the 
eare with which the text of their joint production has evidently been 
prepared, there now appears every prospect of our soon possessing in 
a moderate compass a complete description of the British Crustacea. 
No doubt the numerous species, especially of Entomostraca, which 
have been discovered in our waters since the publication of the 
works alluded to at the commencement of this notice, render a revi- 
sion of them desirable ; but in the meanwhile the student of Crustacea 
will be able to advance far upon his course of investigation with the 
aids already in his hands. 
The classification adopted in the work now under consideration 
agrees with that given by Mr. Spence Bate in his “Synopsis” of the 
Amphipoda already referred to; that is to say, he suppresses the 
order Leemodipoda altogether, and divides the Edriophthalma into 
the two great orders Amphipoda and Isopoda. The former of these
