we are in a position to give a more detailed description of its 
contents in the Special Part (see p. 13). 
Milne-Ed WARDS, II. et A. Recherches pour servir h Fhistoire 
naturelle des Mammiferes. Paris, 1868. 4to. 
The principal object of this work is to describe and figure 
the new additions to the Collection of Mammalia in the Paris 
Museum. The authors, in accordance with the present state of 
science, will pay as much attention to the anatomy as to the 
external characters of the species selected. 
The first three parts have been published, and contain : — 1. A 
memoir by M. II. Milne-Edwards, entitled ^^Considerations sur 
la classification naturelle des Mammiferes. 2. A memoir on 
Hippopotamus liber'iensis , by M. A. Milne-Edwards, accompanied 
by 5 plates. 3. Some plates illustrative of a memoir, by the 
same, on the Mammals of Northern China, which will appear 
in the next part. 
The complete work will form one volume of letterpress with 
an Atlas of about 100 plates, several of which are coloured. Each 
part contains five plates and about 20 pages of letterpress. 
Carus, J. V., und Gerstacker, C. E. A. Handbuch der Zoo- 
logie. Wirbelthiere, bearbeitet von J. Victor Carus. 
Band I. Erste Halfte. Leipzig, 1868. 8vo, pp. 432* 
This handbook of zoology has been prepared in such a manner 
as to be useful to the beginner as well as to the more advanced 
student: Also it may prove to be a very welcome guide for the 
teacher. Prof. Carus, who has undertaken the Vertebrates, and, 
in the volume befovfe us, carried on the work to the Saurians, 
gives a very complete resume of the anatomical peculiarities of 
the classes, adding a short account of the principal fossil forms, 
and enters more into the details of generic distinctions than is 
the case with the majority of similar handbooks. But it is our 
duty to remark that the author, in his attempt at a tolerably 
complete enumeration of genera, has failed to keep it free from 
those errors to wliich every compiler is exposed when not speci- 
ally acquainted with the subject. However, these errors do not 
detract from the usefulness of the work to those for whom it is 
intended ; and we hope that a similar handbook may soon be 
prepared for the English student.
