220 PROCEEDINGS OF THE INDIANA ACADEMY OF SCIENCE. 



Indiana MoUusca, with localities, in which 276 species of mollusks are credited 

 to the State. 



In 1898, Frank C. Baker (Warren, R. I., Dec. 14, 1867 ) of the Chicago 



Academy of Sciences, published a valuable report on the mollusca of the 

 Chicago area, which contains a good deal of matter relating to Indiana 

 localities. 



In 1885, D. R. Moore and Amos W. Butler published in the Bulletin of 

 the Brookville Society of Natural History a list of the land and freshwater 

 mollusca observed in Franklin County, Indiana. This paper enumerated 

 63 species as occurring in that county, and was, up to then, the most important 

 local list of Indiana mollusks that had been published. 



In 1893, E. Pleas printed in the NAUTILUS a list of some 123 species 

 and subspecies of mollusks found within five miles of his home near Dunreith. 

 This is a mere list without annotations. 



Charles Dury of Cincinnati has published some brief notes on the mollusks 

 of the vicinity of Cincinnati in which mention is made of some Indiana lo- 

 calities. 



Ulysses O. Cox, in 1893, published some notes on the mollusks of Randolph 

 County, Indiana. 



The late Josiah T. Scovell (Vermontvillo, Mich., July 29, 1841— Terre 

 Haute, Ind., May 8, 1915) one of the founders of this Academy and until 

 his death in 1915, an honored member, during the years of his long resideni^e 

 at Terre Haute, was deeply interested in the UnionidsB of the Wabash River, 

 as was also the present writer while a resident of Terre Haute from 1886 to 

 1891. We worked together in collecting, caring for and studying the shells. 

 Many a day we spent together wading in the Wabash searching for new or 

 desirable specimens and manj- an evening was even more pleasantly devoted 

 to studying, identifying and arranging our collections. The freshwater 

 mussel fauna of tliat portion of tlie Wabash is a remarkably rich one, as 

 evidenced l)y the fact that our collections contained representatives of at 

 least 47 species of Unionidae taken within 10 miles of Terre Haute. 



During the physical and biological survey of Lake Maxinkuekee, con- 

 ducted more or less intermittently from 1899 to 1913, much attention was 

 devoted to the Unionda? of tliat lake. These studies were carried on by Dr. 

 J. T. Scovell, H. Walton Clark and (lu> present writer. Special attention 

 was given to the life histories of the different species, and it is doul)ted if 

 the molluscous fauna of any other body of water in America has been so 

 thoroughly studied. The number of species of Unionidae known to inhabit 

 this lake is 13, one or two of them, as Lampsilus luteolus, being very abund- 

 ant and of commercial importance. 



In 1903, T. J. Headlee and James Simonton made a study of the mussels 

 of Winona Lake, from which they recorded eight species. In the same year 

 Blatchley and Daniels published a paper on som(> mollusca known to occur 

 in Indiana.
