NATURAL SCIENCES OF PHILADELPHIA. 235 



Jones, Dr. Wm,, U. S. N. Mollusks in alcohol from the Pacific 



Coast of America. 

 Leidy, Dr. Jos. Specimens of Pecten Magellanicus from Noank, 



Conn. 

 Mortimer, Capt. J. H. Thirty-four alcoholic specimens of Oceanic 



Mollusca beautifully prepared. 

 Sixteen species of Terrestrial Mollusks, from Mauritius and 



Madagascar, were purchased. 



At the last meeting of the Academy the reception of the Terres- 

 trial Shells of the Swift Collection was announced, and the thanks 

 of the Academy were ordered to be conveyed to Mr. Thomas Bland, 

 for the care exercised by him in labelling, arranging, and forward- 

 ing the specimens. The remaining part of the collection is now 

 in the hands of Prof. 0. A. L. Morch, of Copenhagen, to whom 

 it had been sent for determination. The two portions form the 

 finest collection of West Indian shells in existence, and when 

 arranged in our Cabinet will be a valuable addition to a collec- 

 tion which is alread}^ one of the largest in the world. 



Apart from arranging the specimens received during the year, 

 the work of the Section has been confined to the preparation of a 

 reference index to the collection, the arrangement of which, as I 

 had the pleasure of reporting last 3^ear, was completed during 

 1873. This index, embracing 1574 generic and family names, was 

 rendered necessary by the extent of the collection, and has been 

 found of great service by those wishing to examine particular spe- 

 cies. 



All of which is respectfully submitted, 



Edw. J. Nolan, M.D., Conservator.
