554 Recently 'published Ornithological Works. 
The first portion of the present book (274 pages) contains 
a series of “ keys ” to the genera and species, which are 
practically the same as those which first appeared in the 
above-mentioned work. They are intended to enable the 
enquirer to identify any bird without much trouble, and 
seem to be well devised for that purpose, though the system 
suggested is somewhat novel. The second part contains 
descriptions of the 398 species of birds which are known 
to occur in the two States of Illinois and Wisconsin. It 
also gives an account of their nests and eggs, so far as they 
are known, and of their geographical distribution, together 
with more or less brief biographical notes. 
The arrangement employed is that of the American 
{ Check-list/ though we observe that several improve¬ 
ments” on it are introduced. For instance, e< Dumetella” 
(p. 265) is substituted for “ Galeoscoptes”; but we are not 
informed who is the authority for this emendation, or the 
reason for it. Again, we regret to see that our old friend 
“ Trochilus ” of Linnaeus is to be superseded by Archilochus ! 
This, we are told, is the dictum of the Committee of the 
A. O. U. on nomenclature, but the reason for the change is 
(perhaps prudently) omitted. 
A great number of text-figures, mostly excellent, illustrate 
Mr. Cory 5 s work, and, together with the u keys,” will render 
it useful to the student. At the same time, we fear that the 
great weight of the volume (caused by the heavy paper on 
which it is printed) may somewhat interfere with its sale. 
58. Hartert on the Birds of Hainan. 
[The Birds of Hainan. By Ernst Hartert, Ph.D. Novitates Zoologicse, 
xvii. p. 180 (1910).] 
After a short disquisition on previous work on the birds 
of Hainan, which was commenced by Swinhoe in 1868, and 
continued by Whitehead, who lost his life in its dangerous 
climate, Dr. Hartert proceeds to give us a complete account 
of the series of specimens formed by a Japanese collector, 
Katsumata,” who was sent to the island by Owston, of
