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 Museum 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 birds," to the satisfaction of all, than any other 

 work published. The authorship is sufhcitnt proof of its accurate- 

 ness which is much in its favor, especially at the present time 

 when so many questionable books on natural history subjects 

 are appearing. The author states in the introduction that 

 an attempt has been made so to group, figure and describe our 

 birds that any species may be named which has been definitely 

 seen. The birds are kept in their systsmatic 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, Page & 

 Company of New York City are the publishers. — J. S. H. 



Errata — In February, '04, Naturalist, p. 98, line 27, read 

 '■ formerly labled Asplenium " for " formerly called Asplenium." 



In Bulletin of the United States Fish 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 study which seems to be much 

 neglected by American botanists. Two hundred and ele\-en 

 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, 

 Cincinnati, 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 ha\-e examined this 

 magnificent work. — Charles Durv, Avondale, Cincinnati, Ohio.
