the chief literary work of his life is the History of the Hibernian

NOTES AND NEWS. 
PLANORBIS NAUTILEUS L. 1y AmMERicA.—The occurrence of this 
well-known European species in the United States has hitherto rested 
upon its discovery at Ann Arbor, Michigan, by De Tarr and Beecher, 
who described it as new under the name of Planorbis costatus. 
Several years ago, among some Vallonia pulchella Mill., purport- 
ing to come from Eaton, N. Y., a single specimen of this Planorbis 
was found. The collector of these specimens was unknown, so that 
no further information was obtainable, and, in view of the possibil- 
ity of some accidental mixture of specimens, I have refrained from 
making a record based on a single example, which might be erron- 
eous. Recently, however, I have received specimens of this species 
about which there can be no doubt, and which, taken in connection 
with the Michigan locality, render the New York citation fairly 
probable. Mr. O. A. Nylander, of Caribou, Me., is the fortunate 
discoverer of the new locality for this beautiful little species. He 
_writes that he found it in Barren Brook, Aroostook County, Maine, 
in three or four inches of water under logs and bark associated with 
Planorbis parvus, bicarinatus and trivolvis. It hardly seems possible 
that in this locality, so remote from foreign commerce, the species 
could have been introduced by human agency. And in this con- 
nection it is a fact of some significance, that in the same brook is 
found a small Pisidiwm, which Dr. Sterki says is apparently identi- 
eal with the European P. milium Held., and that the only other 
known American locality for that species is northern Michigan. 
It is possible that the small size of the shell and its superficial re- 
semblance to a very young Planorbis exacutus Say, has caused it to 
be overlooked by collectors, and that it will be found to have sub- 
stantially the same range over the northern part of this continent as 
other cireumpolar species Bryant WALKER, Detroit, Mich.
