558 The American Naturalist. [June, 
Regarding the affinities of Brachiopods, Shipley says, after mention- 
ing their former association with Molluscs, Tunicates, Polyzoa, etc.: 
“As far as I am able to judge, their affinities seem, perhaps, to be more 
closely with the Gephyrea and with Phoronis than with any of the 
other claimants; but I think even these are too remote to justify any 
system of classification which would bring them together under a com- 
mon name.’ 
Judging by this single volume, the series promises well. It is well 
illustrated by new figures; its language is clear and simple, and seems 
well adapted for those who, while not professional naturalists, wish to 
know something more than they get from their college course, as well 
as for those ‘who, deprived of suitable instructors, wish to go farther 
into zoological subjects than they can without aid. 
Marshall’s Biological Lectures and Addresses.’—A series 
of thirteen lectures, delivered by the late Arthur Milnes Marshall, 
between the years 1879 and 1890, has been published in book form 
under the supervision of C. F. Marshall. Among them are four Presi- 
dential addresses to the Manchester Microscopical Society and the dis- 
cussion of the Recapitulation Theory which formed the subject of an 
address before the Biological Section of the British Association of 
Leeds in 1890. The articles are written in a clear and direct style, 
and are admirably adapted to instruct the general reader. We can 
recommend the book as introducing the principal problems of modern 
biology to the reader in an agreeable and comprehensible manner. 
Butterfly Hunters in the Carribees.’—A pleasing little book, 
purporting to be the adventures of two boy naturalists, with their tutor, 
in the West Indies. The author carries the party safely through a 
number of adventures ingeniously contrived to bring out some scien- 
tific or historical fact. A good deal of information is imparted in an 
agreeable way, in some cases, however, not entirely reliable in its state- 
ments regarding matters not falling within the domain of lepidopter- 
ology. Thus, on p. 54, it is stated that a snapping-tortoise was found 
by the explorers! and, on p. 60, that they examined a snake allied to 
the pine snake of N. America, which squeezed the arm of its captor. 
In another place, the author lets the reader infer that blood-sucking
