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 Siboga 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-
