accepting the division of the gelatinous Radiata into the two classes 
of Hydrozoa and Anthozoa, has nevertheless retained the group of 
Acalephze in its entirety, as including the Meduse (both naked- and 
covered-eyed), the Ctenophora, and the Siphonophora ; and, as far as 
his book is concerned, we find no indication of the arrangement of 
the animals below the Annulosa into one or more subkingdoms. This 
we cannot but look upon as a defect ; and we also regret to see the 
term Protozoa applied only to the Sponges and Rhizopoda as distin- 
guished from the Infusoria. 
Having thus stated the few objections which we have to make 
against the new edition of Professor Rymer Jones’ work, we may 
proceed to the more pleasing task of saying a few words in iis 
praise. Besides the important changes in system already adverted 
to, we may notice the great care and industry displayed by the 
author in bringing together the more important results of the recent 
researches of comparative anatomists and physiologists, and the skill 
with whtch he has incorporated his new matter with the exceed- 
ingly elegant text of the former edition, which is probably familiar 
to most of our readers. The typographical execution of the work, 
and the beauty of the woodcuts, the number of which is increased 
by the addition of several new and important figures, also call for 
all praise; and it may safely be said that we have no treatise on 
Comparative Anatomy, in the English language, that can at all com- 
pare with it. 
Sketches of the Natural History of Ceylon, with narratives and 
anecdotes illustrative of the habits and instincts of the Mammalia, 
Birds, Reptiles, Fishes, Insects, §c., including a Monograph of 
the Elephant and a description of the modes of capturing and 
training it. By Sir J. Emerson Tennent, K.C.S., LL.D. 
Small 8vo. London, 1861. Longmans. 
As this work consists chiefly of an enlarged reproduction of the 
Zoological chapters of Sir James Tennent’s general description of 
Ceylon, which we noticed at some length in this Journal (Annals, 
December 1859) at the time of its appearance, we need do little 
more than call our readers’ attention to thé fact of its publication. 
The author tells us that in preparing his former work for the press 
he found it necessary to curtail the zoological chapters somewhat, as 
they would otherwise ‘‘have encroached unduly on the space re- 
quired for other essential topics.” In his ‘Natural History of 
Ceylon’ he has restored the suppressed passages, consisting to a great 
extent of anecdotes illustrating the habits of the animals described, 
and he has also taken the opportunity of introducing some fresh 
materials, The volume also contains the Treatise on the Elephant, 
which formed part of the second volume of the larger work ; and 
into this we notice that the author has introduced several fresh 
anecdotes and remarks. 
Next in importance and interest to the chapters on the Elephant 
are those on the Reptiles and Fishes of Ceylon, the latter being par-
