small compass. His tendencies with regard to nomenclature 
we have already discussed (‘ Ibis,’ 1906, p. 722). 
The well-written text is extremely full of information, of 
which the completeness may be judged from the fact that 
we have only the following suggestions to offer. The 
Chaffinch occasionally nests on the ground, even in England ; 
the Tree-Sparrow builds more commonly in walls, and tie 
Rock-Pipit in grassy banks, than Mr. Jourdain seems to 
imagine; the Tree-Pipit sits more closely than the text 
would imply; and the Meadow-Pipit is credited with too 
great a love for marshy places as nesting-sites. 
The plates, which are a great improvement on those of the 
earlier part, contain figures of the eggs of Larks, Pipits, 
Wagtails, Tits, Creepers, and Shrikes, of the Cuckoo, the 
Black Vulture, the Common Buzzard, the Rough-legged 
Buzzard, the Great Black-backed Gull, and the Great Auk. 
Of the eggs of the last-named four fine examples are 
depicted, but those of the Buzzards are on the whole a little 
dull; while the well-known grey specimens with blackish 
spots are not represented among those of the Tree-Pipit. 
The letterpress treats of Finches, Buntings, Larks, Pipits, 
and Wagtails.

November, 1906. Redigeret af O. Helms. | 
We have the pleasure of welcoming a new addition to the 
list of journals devoted to Ornithology, of which we have 
lately received the first number. It is the organ of the 
lately-formed Danish Ornithologists’ Union (Dansk Ornith- 
ologisk Forening), and is edited by Prof. Helms, of Haslev. 
After an introduction explanatory of the general character 
of the new Journal we have an article by M. Klinge on the 
migratory birds of 1906, and a description by Mr. A. T. 
Hagerup of the nesting of Sylvia nisoria in Denmark. 
These are followed by shorter notes and notices. We are 
sure that many English ornithologists will be glad to know
