1875.J 11 [Annual Report. 



sottdissima, a common New England clam ; Tellinidae by 

 Scrobicularia piperita ; the only reason for taking this form 

 to illustrate the family Tellinidae was that figures of no 

 other good forms were accessible ; Veneridae by Callista 

 Chione, a very common European mollusk — it is proposed to 

 make soon a model of our Venus mercenaria, to further 

 illustrate the family ; Cyprinidae by Cyprina islandica, the 

 only species at present recognized in the family. 



The collection of New England shells has been entirely 

 revised and remounted, the color of the tablets having been 

 changed from black to dark blue, and the labels rewritten. 



Most of the general collection has been received from 

 Dr. Carpenter; but he still retains, and is at work upon, 

 several groups, including the Neritidae and Cerithiadae. He 

 has not yet completed his work upon the duplicate collec- 

 tions, and they also remain in his possession. 



Besides the catalogue of the general collection in course 

 of preparation by Dr. Carpenter, there has been made out 

 the past year for the use of the Society, a general catalogue 

 of the New England collection, and a catalogue of the testa- 

 ceous mollusca known to have been found on the New Eng- 

 land coast. The latter was compiled from the several works 

 on New England Zoology. 



The principal additions to the collection of Mollusca, re- 

 corded for the past year, are : — A lot of about one hundred 

 species of dried specimens of lamellibranchs and gasteropods, 

 collected in Florida and the Bahamas, by Dr. E. Palmer, and 

 obtained for the Society by purchase ; a number of foreign 

 marine shells from the relatives of the late Mr. F. P. Atkin- 

 son ; and many marine or fresh water shells, mostly from the 

 Southern States, contained in the collection of the Messrs. 

 H. B. and W. D. Rogers ; besides the large collection made 

 by the Custodian and Mr. Rathbun, while with the U. S. Fish 

 Commission, at Noank, Conn., during the summer of 1874.
