REPORT OF THE DIRECTOR. 15 



14. From the Smithsonian Institution, in 1869, a collection 

 of European shells labeled by Mr. P. P. Carpenter, containing 

 five hundred and fifty-six species. Twenty-fifth Annual 

 Report, pp. 39-55. 



15. From T. H. Aldrich, Selma, Ala., one hundred and 

 thirteen species of United States fresh-water and land shells. 

 Catalogued in the present report. 



A large number of shells, principally marine, were contained 

 in the Pickett and Gebhard collections which were purchased 

 by the State. Several years ago (previous to 1866), Mr. W. 

 H. Schram, of Sandlake, N. Y., contributed to the State 

 Museum a collection of shells, which remained unacknowl- 

 edged in our reports, and not unpacked until the past year, 

 when the source from which they were derived was ascer- 

 tained, and they are now duly credited. 



A valuable donation of nearly a hundred species of Unio, 

 with many duplicates, from Mrs. E. Emmons, has been 

 received. A number of other contributions have been of 

 special value, although consisting of comparatively few species. 



The Gould collection is arranged separately ; and the 

 Regents have provided, that the Mazatlan collection " shall be 

 kept distinct and open to the examination of students ; " and 

 the Director, appreciating the value of local investigations 

 and collections, and in order to encourage them, has given his 

 assurance that the suite of Long Island Mollusca shall also 

 be maintained as a separate collection. 



A series of the Mollusca of our own State, as full as our 

 present material and knowledge permits, has been arranged 

 in the table-Cases of the New York Invertebrata. 



A large number of land and fresh- water shells of the United 

 States have accumulated in the Museum during the Geological 

 Survey and in subsequent years ; they have been brought 

 together, cleaned and partially arranged in drawers. As a 

 large proportion of them are not authentically named and 

 without record of locality, it is proposed to submit them, 

 during the present year, to the revision of Dr. James Lewis, 

 of Mohawk, N. Y., whose acquaintance with these forms, 

 from the study of them for many years, fully fits him for their 

 determination, and reference to probable source. These 

 materials will furnish a full suite for the Museum, and an
