340 THE AMERICAN NATURALIST.  [Vor. XXXVI. 
An isopod parasitic on the small hermit crabs found in the vicin- 
ity of Woods Hole is described by Millett T. Thompson (Bulletin 
United States Fish Commission, 1901, pp. 53-56, Pls. IX, X). The 
female parasite is found on the abdomen of the host, the compara- 
tively small male being attached to the marsupium of the female. 
The isopod, probably representing a new genus allied to Phryxus 
resupinatus Müller, has been named Stegophryxus hyptius, the generic 
name being given in reference to the covering of the female, as it 
lies upon the host, by its marsupium. 
Prof. Carl H. Eigenmann reports on his investigations into the 
history of the young squeteague of Buzzards Bay and Narragansett 
Bay (Bulletin United States Fish Commission, 190t, pp. 45-51). 
The young fish are pelagic in habit, subsisting entirely upon shrimp 
and smaller fish. The report considers further the distribution of the 
young squeteague, their rate of growth, and the changes accompany- 
ing growth, in body proportions and coloration. 
Captain Tuttle of the revenue cutter Bear has presented to the 
Museum of Stanford University a pair of native boots which he 
brought back from. a recent visit to the north, and which were-made 
by a native on St. Lawrence Island in the Bering Sea from the skin 
of a half-grown bull fur seal, taken in the winter of 1900 in the ice 
adjacent to the island. St. Lawrence Island is 500 miles to the 
northward of the Pribilof Islands, and it is interesting to note that 
this is the first time the fur seal has been taken at s considerable 
distance north of the Pribilof group. 

BOTANY. 
De Bary's Bacteria. — The wisdom of a third edition of de Bary's 
Vorlesungen über Bakterien! so long after the death of its author 
may well be questioned. New discovéries on every hand have 
revolutionized old views, and to properly revise such a work would 
require it to be doubled in size and practically rewritten. This 
Dr. Migula has carefully refrained from doing. The title-page 
reads, * Dritte Auflage durchgesehen und teilweise neu bearbeitet 
von W. Migula," and in the preface apologies are offered for lack
