July jo, 1886. — Regular Meeting. 



President C. E. Putnam in the chair; twelve members and a number 

 of visitors present. 



Curator reported some very valuable additions to the museum, the 

 most notable of which was a collection of sixty-three species of fossils 

 from the Paris basin, by Prof. Barris; and a number of exceedingly 

 beautiful specimens secured by himself on a recent trip to the crinoid 

 beds of Marshalltown. 



Prof. Hatch reported a trip to the Ozark Mountains, and collections 

 in botany and zoology. 



S. M. Tracy, Professor of Botany in the University of Missouri, being 

 present, was called upon, and made a few remarks in a very pleasant 

 and complimentary strain, commenting on the advantages enjoyed by 

 the members of the Davenport Academy. 



Drs. Hoepfner, Jaenicke, and Matthey, and Mr. M. H. Calderwood, 

 of Eldridge, were elected to regular membership, and Mr. C. T. Simp- 

 son and Rev. J. P. MacLean as corresponding members. 



H. A. Pilsbry presented a paper describing "A New Hydrobinoid 

 Mollusk, with Notes on Other Rissoidae." 



Mr. Pilsbry also gave an interesting account of some "plants" of 

 mollusks near Davenport. During a recent collecting trip to Sylvan 

 Water, he found a mollusk new to the Mississippi River. On showing 

 it to the Curator of the Academy, he was referred to Academy Pro- 

 ceedings, Vol. II., p. 26, where an account is given of Mr. Pratt having 

 brought from Peoria, Illinois, fresh-water shells not found in this vicin- 

 ity, and transplanting some of the living shells into Sylvan Water. Mr. 

 Pilsbry's findings, ten years later, show that their new station proved 

 favorable to the mollusks. He further desired to have recorded the 

 planting of a land mollusk, Mes. Albolabris, on the Island, the speci- 

 mens being from Des Moines. 



In view of the approaching National Convention of the Agassiz 

 Association, to be held in this city, the Academy voted to appoint com- 

 mittees to cooperate with the local Agassiz Clubs in any way which 

 might be conducive to the success of the meeting.
