those islands. Quite a number of individual collectors contributed 

 to the Hawaiian series, among others, Miss Olga Smith, Mr. Irwin 

 Spaulding, and Mr. Walter D. Giffard, all of Honolulu, and Mrs. 

 Edna Bowen, of Hanalei, Kauai. To Dr. W. L. Abbott we owe 

 1,346 specimens of land shells from Haiti and a number of others 

 from Santo Domingo, all of his own collecting, while several of the 

 accessions from Australia are the results of Mr. Hoy's collecting, all 

 of these collections containing large numbers of noteworthy mollusks. 

 The Smithsonian African expedition also contributed several collec- 

 tions of mollusks, and from the Philippine Islands several welcome 

 additions were received from Mr. C. F. Baker, P. I.; Dr. David 

 T. Gochenour, Stuarts Draft, Va. ; and Mr. H. N. Lowe, Long Beach, 

 Calif. ; the latter two containing types of new species. Our relatively 

 small collection of South American mollusks has been increased by 

 several individual collections, nearly all containing new species, from 

 Dr. C. Wythe Cooke, Washington, D. C, specimens from Co- 

 lombia; from Dr. H. Pittier, Caracas, Venezuelan mollusks; from 

 Dr. F, Felippone, Montevideo, specimens from Uruguay and 

 Brazil. Shipworms, material of which is always desirable, were re- 

 ceived from the division of biology of the science and agricultural 

 department of Demerara. Mr. Ralph W. Jackson, Cambridge, Md., 

 contributed a number of marine shells, including types of two new 

 species, and Dr. Mario Sanchez, Habana, Cuba, a similar collec- 

 tion containing five types. 



Prof. A. S. Pearse, Madson, Wis., deposited a large number of 

 types and other material of parasitic worms, and material transferred 

 by the Bureau of Fisheries contained two of Doctor Linton's cestode 

 types. 



Echinoderms. — Through Prof. Max Weber the division obtained 

 267 specimens of unstalked crinoids, from the Dutch East Indies, in- 

 cluding about 40 species new to our collection and many cotypes, all 

 collected by the Dutch Sihoga expedition. From the German South 

 Polar expedition, through Prof. R. Hartmeyer, 23 specimens of 

 unstalked crinoids from the Gauss expedition, all new to our collec- 

 tion, were similarly received. The State University of Iowa's Bar- 

 bados-Antigua expedition, through Prof. C. C. Nutting, contributed 

 71 specimens of ophiurans, nearly all from localities unrepresented in 

 our collection. 



Plants. — The National Herbarium has been increased during the 

 year by over 14.000 specimens from Haiti and Santo Domingo col- 

 lected by Dr. W. L. Abbott, and Mr. Emery C. Leonard, of the di- 

 vision of plants. The Bureau of Plant Industry, of the Department 

 of Agriculture, transferred 9,673 specimens, including 4,298 speci- 

 mens of grasses. The collection contained about 3,000 specimens from 

 Siam. Burma, and Assam, recently collected by Mr. J. F. Rock, be-
