6 REPORT ON ZOOLOGY, MDCCCXLIII. 



2 Hefte. 4. (Monographs of the Mammalia, with figures 

 drawn from Nature, and the best w r orks on Natural History, 

 by Kull, &c.) 



Tlie author proposes to exhibit the species of Mammalia monographically, 

 in descriptions and coloured figures. The first part treats of the genera, 

 Macroscelides, Ailurus, Tlii/lacinus, and Myrmecolivs; the second part, of the 

 Rhinoceros species. Neither part contains anything new; the figures, mostly 

 copies, are well executed. If the work proceeds with certainty and rapidity, 

 it will prove very useful in facilitating the determination of species in col- 

 lections. 



Chr. v. Trautwetter has attempted, in his ' Novum Systema Theriologi- 

 cum,' also a new systematic arrangement of the Mammalia and Birds.

This memoir is intended to refer only to those species which were un- 

 known to Buffou, or respecting which he had but incorrect information. The 

 most common sources only have been here referred to ; and the work will 

 certainly not bear comparison with Scheitliu's ' Thierseelenkuude.' 



Observations on the Classification of the Mammalia. By 

 G. B. Waterhouse. (Ann. Nat. Hist, xii, p. 399.) 



The orders of Mammalia are represented by circles, which Waterhouse 

 attempts to group in such a way that they may correspond to the mutual 

 alliances of the orders. I place no especial importance in systematic ex- 

 positions of tliis kind, since they never completely answer their professed 

 object. Thus, in the present instance for example, the Carnivora and Pachy- 

 dermata border upon each other, although anything but a transition is prc- 

 M'nled by the Hog, which is indicated as a connecting link; on the other 

 hand, the former are widely separated from the Marsupiata, although a mani- 

 fest transition between these classes exists. Since every order is connected 

 with others on various sides, it is not possible to exhibit correctly in a 

 figurative expression the real affinities, or even merely the analogies, which 

 exist between these divisions. This can be done clearly and completely 

 only in words.
