vast numbers. The stream has a mud bottom which is much in¬ 
dented with cow tracks. In these the Amnicola had congregated— 
not as a layer on the surface, but as a solid mass. To get an idea 
of how many there were I scooped up the contents of three holes, 
and after washing them thoroughly, found I had a full quart of the 
living animals. There must have been bushels of them in the few 
rods of stream which I inspected. The stream receives some of the 
city sewerage, so it is probably a good feeding-ground. 
The geese which infest the neighborhood do not seem to care for 
this species. —H. E. Sargent, in lit. 
NEW PUBLICATIONS. 
The Life and Writings of Constantine Samuel Rafines- 
que, by Richard Ellsworth Call, is announced to be published in 
January next. The volume will be in quarto form, and issued in 
paper only. It will contain several full-page illustrations, one of 
which will be a portrait of its subject. A complete bibliography of 
the writings of Rafinesque, on every subject, comprising over four 
hundred titles, will be included, together with a certified copy of his 
will, one of the most remarkable testamentary documents ever pro¬ 
bated. It will prove of exceptional value to those interested in 
botanical, conchological, or ichthyological matters. 
A Monograph of the Land and Freshwater Mollusca of 
the British Isles, by J. W. Taylor, F. L. S., is announced as in 
press. The object in issuing this work is to bring together, as far as 
practicable, all reliable information bearing upon the study of the 
British Land and Freshwater Mollusca. It will aim to combine 
the information upon all aspects of the study, and thus form a 
standard work of reference as well as a reliable text-book upon 
British Land and Freshwater shells. The first volume will be de¬ 
voted to general characters of the shell, the morphology of the ani¬ 
mal, geological and geographical distribution, habits, parasites, etc. 
The second volume will be devoted to the treatment of species in¬ 
dividually, and will aim to give accurate descriptions and faithfully 
colored figures of the typical shell and the chief varieties of every 
species; the various organs of the animal will be described and 
illustrated in the text, and full lists of localities, with a full syn¬ 
onymy will also be given, as well as observations upon the habits 
and peculiarities of each species. Mr. Taylor’s work promises to be 
a timely and useful one. Fuller notice will be given upon the ap¬ 
pearance of the first volume.
