been done, and the scope of Protection has been widened to 
include birds’ eggs and such species as are used for millinery 
purposes—in the latter case with especially gratifying 
results. Game-birds are constantly imported to increase 
the stock, the Capercaillie, Black Game, and so forth have 
been introduced in a way unknown in other countries, while 
the Secretary of Agriculture is not only entrusted with the 
supervision of all imported species, with the view of protecting 
Agriculture from pests, but is empowered to collect and 
publish all information likely to be useful. 
The annexed maps give an excellent idea of the action of 
the various States, the spread of the doctrine of preservation, 
and the different Reserves. 
19. Parrot on the Corvide. 
[Zur Systematik der paliiarktischen Corviden. Von Dr, C. Parrot. 
Jena: 1906, pp. 257-294. ] 
This article, reprinted from the ‘ Zoologische Jahrbiicher,’ 
contains an account of the Palzarctic Corvide (namely 
Corvus cornix, C. corone, C. macrorhynchus, C.m. japonensis, 
C. m. levaillanti, C. corax corax, C. c. umbrinus, and C. c. 
cacolotl) as understood by the author. The whole question 
of their status is brought under discussion as well as their 
points of difference and relations to kindred forms. 
20. Rey’s Eggs of Middle Huropean Birds. 
[Die Eier der Végel Mitteleuropas. Von Dr. Eugéne Rey. Bandi. Text. 
Band ii. Tafeln, Kohler: Gera-Untermhaus, 1905. Price (abt.) £3.] 
Dr. Rey’s work on the eggs of the Birds of Middle Europe, 
of which we noticed the commencement in ‘The Ibis’ for 
1900 (p. 212), is now complete in 30 parts, and, as finally 
arranged, forms two solid octavo volumes, the first of which 
contains the text (682 pp.) and the second the plates (128 in 
number). We spoke favourably of this book in our previous 
notice, and need not repeat what was there said. It is 
certainly a cheap work for its price, and will be found con- 
venient for reference by our egg-collecting friends. The 
letterpress is in some cases rather concise, but contains 
most of the necessary particulars,
