164 Recently published Ornithological Works. 
Parrots, and Doves as have been received alive in Europe. 
Of all these birds, after the scientific and English name, a 
short description is given, with an abstract of the principal 
facts known about them. About 80 illustrations are included 
in the text, some of which are of special interest. 
We must say that all our friends the Aviculturists ought 
to be exceedingly grateful to Mr. Butier for the pains he has 
taken in the compilation of this book, which will save them 
enormous trouble. To ascertain the name of a living bird is 
no easy matter nowadays. All sorts of books and periodicals, 
many of which may not be of easy access, must be searched 
through, and perhaps in vain ! We do not say that this work 
will enable us to solve the riddles at once, but it will be a 
considerable help. We cordially commend Mr. Butler's 
book on cage-birds to the notice of all those who keep 
our feathered friends in captivity and wish to know their 
scientific names.

that is, “ the Continent of North America north of the United 
States and Mexican Boundary, Greenland, and the peninsula 
of Lower California, with the islands naturally belonging 
thereto.'’ 
The species are not numbered in the present edition, but 
are stated to be about the same in number as those in the 
second edition (i. e . 768), besides which there are a large 
number of subspecies. These are indicated by letters (a, b, 
c , &c.). Melospiza has 20 subspecies and Otocorys 14. In 
the main portion of the List the species and subspecies are 
taken in systematic order from the lowest to the highest, and 
after the Latin and English names a reference to the authority
