of the most useful books of reference the entomologist can have 
upon his book-shelves. The original work forms a bulky octavo 
of 690 pages, while the supplement, even, is paged from 691 to 
883. As this contains simply a synonymic list of one group of 
Lepidoptera, one may form some idea of its extent, and the labor. 
involved in its preparation. 
FERNS oF Nortu AmErica.'\—The first part, now before us, more 
than meets the expectations formed when the work was announced. 
Professor Eaton has treated the subject in a clear and methodical 
way; presenting in a popular form detailed descriptions character- 
ized by the great merits of readability and accuracy. The plates 
are well done both by artist and lithographers. In the first part 
the following species are figured and described: Lygodium palma- 
tum, Cheilanthes vestita and coopere, Asplenium serratum. There 
is also a synopsis of the species of Cheilanthes known to occur in 
the United States. This work of so much promise can be most 
heartily recommended to botanical teachers and students. The 
low price at which it is offered is a pleasant surprise to many who 
are familiar with the cost of such productions, and it is to be 
earnestly hoped that the projectors of this enterprise may receive 
_ from the public the support to which it is entitled —G. Z. G. 
~ Frower’s Ostrotocy oF THE Mammarta2—This valuable 
résumé of the osteology of the Mammalia, may be recom- 
mended to those desiring a knowledge of the subject, as the 
best manual in our language. While not exhaustive, it is full of 
information, especially in regard. to cranial characters, and the 
publishing works of this class, preferring in some instances at 
least the position of public instructors to the accumulation of large 
Profits on outlays.
