assistance guaranteed them by all the leading ornithologists of 
Europe, with the support of a good list of subscribers, will make 
the work a decided success in every way. Both the authors are 
well known as practical field naturalists, and the successful man- 
ner in which Mr. Sharpe has just completed his ‘*‘ Monograph of 
the Kingfishers” is sufficient evidence that the work will be carried 
through the press in the best manner possible. 
As the work will hardly be accessible for the private libraries 
of most of the ornithologists of our country, owing to its necessa- 
rily high cost, it should have a place in all our large libraries, 
where those who cannot afford to own the work, can at least have 
a chance of consulting its pages: and as many of our birds are 
identical with those of Europe, and many others very closely al- 
lied, it will become the duty of every one engaged in the study of 
birds to consult this splendid monograph. The work is published 
by the authors, by special permission, at the office of the Zoologi- 
cal Society of London, where we should be Boars to forward the 
names of subscribers.
