564 PROCEEDINGS OF THE ACADEMY OF [1893. 



raises the number to a total of over 3,000 trays received and admin- 

 istered upon by the Conservator during the year. 



Several accessions of special value to our collection may be men- 

 tioned, the collections received from the Peary Relief Expedition, 

 from Dr. J. C. Cox, and that purchased from the Morelet collection 

 being the most important. 



The first of these, for which we are indebted to Prof. Angelo 

 Heilprin, leader of the Peary Relief Expedition, adds a considerable 

 number of Arctic forms first described by Friele, Sars and others, 

 which could hardly have been obtained from any other source. This 

 collection, together with that made by the West Greenland Expedi- 

 tion of 1891, gives us an excellent representation of the Greenland 

 marine fauna. 



The portion of the collection of the late Arthur Morelet of Dijon, 

 France, which was obtained by us includes over 250 species of land and 

 fresh- water shells, mainly of Africa, India and South America. As 

 they are all new to the collection, and accompanied by reliable data, 

 the great value of the series will be apparent. The additions to our 

 collection of Helices are especially notable, many rare and long 

 needed species being secured. 



Dr. J. C. Cox of Sydney, N. S. Wales, Australia, has with 

 great liberality made two donations to the Academy. The first, re- 

 ceived through the Treasurer of the Section, contains a collection 

 of dry Chitons from the coasts of New South Wales and South Aus- 

 tralia; the second was transmitted direct to the Conservator, and con- 

 sisted of a larger collection of alcoholic Chitons and many rare gas- 

 teropods. The two sendings give us excellent material for the study 

 of Australian Polyplacophora, and include a number of new species. 



Other gifts, smaller but of scarcely less value, have been received 

 from Professor F. W. Hutton of Christchurch, New Zealand, and 

 Professor Jose N. Rovirosa of Tabasco, Mexico. A considerable 

 number of fine shells, including a good suite from the Grecian Archi- 

 pelago, was received from Mrs. G. W. Carpenter of Philadelphia. 



A large number of the interesting land shells of New Zealand 

 have been obtained by purchase from Mr. H. Suter of Christchurch, 

 N. Z. A large proportion of them were figured for the first time, in 

 the Manual of Conchology. 



The additions to our suites of North American shells have been
