THE NAUTILUS. 11 



BOSTON MALACOLOGICAL CLUB. 



A few persons interested in the study of Mollusc.a were entertained 

 on the evening of Washington's birthday, by Mr. Francis N. Balch, 

 at his home in Jamaica Plain. Plans were discussed and a meeting for 

 organizing was called. As a result, thirteen melon March 14th, in 

 Boston, adopted a constitution, and elected Prof. Edward S. Morse, 

 of Salem, President ; Mr. Francis N. Balch, of Boston, Vice- Presi- 

 dent ; Rev. Henry W. Winkley, of Danvers, Secretary and Treas- 

 urer. Mr. John Ritchie, Jr., and Mr. Chas. W. Johnson were 

 elected to serve with the other officers as an Executive Committee. 



At the April meeting, Professor Morse gave an excellent ad- 

 dress, protesting against the multiplication of generic names, and 

 on some interesting points for study and observation. Mr. Balch 

 spoke on his recent visit to Washington, of some of the interesting 

 specimens obtained by the "Albatross " and of the work being done 

 at the National Museum on mollusks. Some twenty-five ladies 

 and gentlemen are now on the roll of membership.

A NEW SPECIES FOR THE UNITED STATES FAUNA. Mr. VS. H. 



Over of Date, S. D., has recently to me for determination specimens 

 of a Segmentina, collected by him in a small water-hole among the 

 Coteau Hills, five miles north-east of Clear Lake, S. D. They agree 

 very exactly with the description and figure of S. christyi Dall, both 

 in sculpture and size, the largest specimen being 11^ mm. in diameter, 

 and I have no doubt as to their being that species. None of the 

 seven specimens sent show any indications of apertural lamellae. 



BRYANT WALKER. 



A LARGE FOSSIL TRIVIA: Among a collection of Pliocene fossils 

 obtained by Mr. Wm. F. Clapp, from the dredgings in the lower part 

 of Lake Flint, above Ft. Thompson, Florida, was a specimen of Trivia 

 pediculus of an unusually large size. The specimen measures 22 mm.
