ZOOLOGICAL LITERATURE. 
This "woTk is divided into two portions, — (i.) the Generalities of 
the subject, containing disquisitions on (1) various preliminary 
questions, (2) the conditions of local distribution, (3) its tem- 
porary changes and (4) the classification and enumeration of 
the species according to their distribution in North Germany; 
and (ii.) the Specialities, wherein the various birds are dealt 
with systematieally. Herein 490 species are included, and 5 
more added in a supplement. Much care seems to have been 
bestowed on the whole. [Of. Zool. Garten, 1869, pp. 223, 224;

A series of comments, chiefly on the works of Prof. Schlegel 
and MM. van Bemmelen and Albarda (Bouwstoffen voor eene 
Fauna van Nederland, ii., iii.) on the birds of Holland, with 
the latter of which we are not acquainted. The remarks show 
much research, and often contain information of value ; but the 
opinions of the author on nomenclature are not likely to be 
generally adopted in this country. [C/*. Ibis, 1870, p. 270.]

This may be regarded as a supplement to Baron Droste^s

This paper contains the most important contribution to the 
zoology of Northern China that has yet been made. In it 
(iii. pp. 29-41) is the best catalogue of the birds hitherto ob- 
served near Pekin, including 295 species, many of which are 
not named, though it is probable that they can be referred to 
published descriptions; and indeed some are identified [appa- 
rently by M. J. Verreaux] . The only one which seems to receive 
a new name belongs to Motacillidce. One of the most interest- 
ing discoveries is that of a species of Swan (see Anatidcn), cer- 
tainly new to the Old World. But the Journal itself contains
