ZOOLOGICAL LITEKATUllE. 
W e can only congratulate Mr. Krelft for having chosen Dr. Gray^s 
Catalogue of Mammalia as his guide, and for not having bur- 
dened this commencement of zoological literature in Australia 
with the useless repetition of descriptions of animals perfectly 
well known. It would appear that the total number of species 
in the Sydney Museum is 283. Most of the Australian species 
are accompanied with notes on their habits or geographical 
distribution. The Catalogue does not contain species which 
have not been described elsewhere. 
J. VAN i)Eii Hoeven. Pliilosophia Zoologica. Lugd. Batav., 
1864. 8vo. 
This work treats of the nature of animals generally, giving an 
outline of the histology, physiology, anatomy and embryology 
of the different classes. The third book is devoted to the 
method of systematic and descriptive zoology, and the last to 
the geographical distribution of animals. In the course of the 
Records, we shall now and then have occasion to refer to this 
work.

We are informed by the editor of the " Annales des Sciences 
Naturelles,^ that Eschricht at the time of his death Ayas engaged 
in the publication of another work on Cetaceans, and that the 
present memoir is merely a fragment of it, taken from the first 
proof sheets. The author had such an extensive knowledge of 
Cetaceans, aud even in this fragment so completely exhausts 
his subject, that we are very glad to hear that the fears ex- 
pressed by M. Milne-Edwards of this work being lost to science 
will not be realized, and that the publication of the manuscript, 
* We must remark that, although the fourth part of this volume bears 
1863 as date of publication on the titlepage, it was not received in this country 
before February 1806.
