NEWS AND NOTES. 
Color Key to North American Birds. — This is a recent 
addition to the ornithological literature of North America from 
the pen of the well known author, Frank M. Chapman, of the 
American Mu.seuin of Natural History, with over 800 illustrations 
in color, by Chester A. Reed, whose drawings and photographs 
have added so much to the value and attractiveness of the “ Bird 
Magazine.” The work is wholly devoid of technicalities, .■-o one 
that is not a specialist as well as one that is may use and enjoy it 
together. It comes nearer answering the question, ‘‘ How can I 
learn to know the l)irds,” to the satisfaction of all, than any other 
work puldished. The authorship is sufficient proof of its accurate- 
ness which' is much in its favor, especially at the present time 
when so man\- questionable books on natural liistorN- subjects 
are appearing. The author states in the introduction that 
an attempt has been made so to group, figure and describe our 
birds that au}- species may be named which has been definitelj’ 
seen. Tlie birds are kept in their systomatic orders, a natural 
arrangement readily comprehended, but further than this, accept- 
ed classifications have been abandoned and the birds have been 
grouped according to color and markings. This in a word gives 
the plan of the book, and any one who desires to know the birds 
afield, will find it a most desirable aid. Doubleday, P.vge & 
Company of New York City are the publishers. — J. S. H. 
Krrata — In February, ’04, Natur.vlist, p. 98, line 27, read 
formerl}’ labled xVsplenium ” for ‘‘ formerly called Asplenium.” 
In Bulletin of the United States F'ish Commission for 1902, 
pages 369-394, Miss Julia W. Snow of Smith College gives the 
results of her work on ‘‘The Plankton Algae of Lake Erie.” 
This is an important contribution to the flora of the lake and 
represents an inviting field of stud}’ which seems to be much 
neglected by American botanists. Two hundred and eleven 
species with a considerable additional number of varieties are 
listed, thirteen of which are described as new. Four good plates 
are given to illustrate the new species. — J. H. S. 
Wytsman's Genera Insectorum in the Lloyd Library, 
CiNCiNN.vn, Ohio. — C. G. Lloyd is subscribing for this great 
illustrated work, and has already received a number of the parts, 
which have been placed in the great Lloyd Botanical Library in 
Cincinnati, O. This library is open free to students who wish to 
Consult any of the books on Botany and Entomology. Through 
the courtesy of Mr. Holden, the librarian, I have examined this 
magnificent work. — Ch.vrles Dury, Avondale, Cincinnati, Ohio.
