96 THE NAUTILUS. 



do not pay more attention to the European forms of tlie circumpolar 

 types. Jiitlfiin^ from the name?, one would suppose that the Ameri- 

 can variations of L. palustris, etc., were quite different from those 

 found in Europe. \i tliis is the case, it is a fact of mucii interest; 

 but it has never been demonstrated by comparisons, nor is it sug- 

 ppsfed by the figures in Mr. liaker's work. The variety ex/fiiiisa 

 Hahl., of //. p'tluslris, is to l)e compared with the European var. 

 coiiifonnis Bnurg., which on the face of things appears to be the 

 same; while otiier American pa/iisfris seem referable to varieties 

 eluiir/ala IMoquin (Baker, PI. xxxii, lirst three shells of fig. 1), and 

 perhaps co/*/ca Jeffreys. In fact, it is not yet clear that there is »ny 

 American variation of L. pa/usfris which cannot be duplicated in 

 Eiu-ope. AVitli regard to A. slui/nalis, it is well said that the ty[)ical 

 European form is not that found in America, but it is apparently not 

 true that the American form {<ippressa Say) is absent from Europe. 

 1 have seen plenty of European specimens which could not, 1 think, 

 be distiniiuished trom the American ones; such appear to pertain to 

 tli3 variety frdyilis (Linne) and its allies. >Some one shoidd 

 minutely examine the anatomy of these forms, to see whether it is 

 not po-!sible that there are two species, viz.: (1) L. stagntilis (I^-), 

 European; (2) L. fragilis (L.), Euro[)e and America, including 

 apprfssd Say. raplinha Hoiu'gt., vuUjuris Westerlund, etc. 



Liiuuf;eti Woo</n'Jfi Baker, appears from the figures to be the 

 European L. peretpa, in which case it must have been introduced

At the NovEMHEU Meeting of the Section on Conciioi.ogv, 

 Brooklyn Institute of Arts and Sciences, Mr. S, C. Wheat exhibilefl 

 two s])ecimens of freshwater mollusca taken from a stream in New 

 Jersey, which, upon careful ins|)ection l>y Dr. R. Ellsworth Call, 

 were pronounced to be hybrids between Margarilaim marqiiiata and 

 Aiiodontd unilukila. The specimens aroused much interest, as such 

 li3'brids are very rare. A speeimen of Anodoidc iinpUcnta seven 

 inches in length taken from Prospect I'aik Lake was also shown. 

 These S|)ecimens were added to the collection in the Children's Mu 

 seum. — F. II. Ames, Sec.
