Theodore Lyman, 6 species ; F. W. Putnam, 7 species ; M. 

 Simon, 5 species ; Mrs. L. L. Thaxter, 3 species ; A. E. Ver- 

 rill, 83 species ; Prof. Wyman, 1 species ; Rev. J. C. Fletcher, 

 19 species. 



With the Gray fund we have secured some valuable contri- 

 butions ; from C. Cooke, Zanzibar, 98 species and 7,500 speci- 

 mens ; from a collection made by Mr. C. Wright, in Cuba, 

 over 100 species ; from W. Stimpson, 127 species, and from 

 C. Shepard, 44 species. 



All the pulmonate Gasteropods in the Museum, except those 

 very recently received, have been mounted, and all the fluvia- 

 tile shells, except Naiadae, are also mounted, and now await 

 suitable space for their proper exhibition, which we hope will 

 not long be wanting. 



Report on the Collection of Brachiopoda, by N. S. Shaler. 



Since the last report, work has been begun upon the collec- 

 tion of Brachiopoda, with a view to reducing the magnificent 

 store of materials, in the possession of the Museum, to the 

 shape best fitted to aid in the advancement of American palae- 

 ontology. 



As the greatest value of the collection consists in the pre- 

 cision with which the locality of the specimens is given, 

 and the importance of the labels attached to them by 

 authors, the first effort was to secure the specimens from 

 all danger of accidental displacement, likely to occur even 

 with the most careful handling. To do this effectually, it 

 was necessary to catalogue the whole collection, after the plan 

 which had been adopted in other departments of the museum. 

 In pursuance of this plan, over twelve hundred lots of speci- 

 mens from palaeozoic horizons, comprising, however, scarcely 

 a tithe of the collection, have been catalogued and numbered ; 

 and it is confidently expected that the coming year will see the 

 whole collection similarly secured against accident. 



The new species collected by the Anticosti expedition in 

 1861, have been described ; and the manuscript is now ready 

 for publication in the" Bulletin." The sub-family of Leptaenidae 

 has been worked up monographically, the specimens mounted
