REPORT OF NATIONAL MUSEUM, 1914. 109 
The following have continued work on collections in their custody 
as opportunity permitted: Dr. R. C. Osburn, of Barnard College, 
on the bryozoans of the northeast coast of North America; Dr. W. M. 
Tattersall, of the Manchester Museum, England, on the Mysidacea; 
Mr. R. Southern, of Dublin, Ireland, on the annelids of the family 
Cirratulide; Dr. J. W. Spengel, of Giessen, Germany, on Sipun- 
culus; Prot. Maynard M. Metcalf, of Oberlin College, on Salpa and 
Pyrosoma; and Dr. Walter Faxon, of the Museum of Comparative 
Zoology, on crayfishes. Specimens have been lent for study to Prof. 
H. Garman, of the State University of Kentucky; Miss Ada L. 
Weckel, of Oak Park, Ill.; Mr. Stanley Kemp, of the Indian 
Museum, Calcutta; and Mr. F. C. Craighead, of Washington. 
Plants—Among the accessions of the year were several of excep- 
tional value, the more noteworthy being as follows: Over 10,000 
specimens were received from the Bureau of Plant Industry and 
the Biological Survey, of the Department of Agriculture, compris- 
ing, besides 1,500 miscellaneous plants, more than 1,200 mounted 
grasses, collected by Prof. A. S. Hitchcock during an investigation 
of this group in Nevada, California, Utah, and Arizona, and also 
6,000 duplicate grasses, consisting of 30 sets of 200 specimens each 
of certain species which have been critically studied by Prof. Hitch- 
cock and Mrs. Agnes Chase in recent years, and of which it has been 
considered desirable to distribute authentic specimens. The New 
York Botanical Garden furnished 3,555 plants in exchange, of which 
562 were African specimens from the Otto Kuntze Herbarium, and 
the remainder entirely from the West Indies, supplementing very 
acceptably the large series acquired from the same source in recent 
years, and resulting from investigations by that institution. Some 
1,580 Chinese plants, representing a second installment of one of the 
largest sets of the exceedingly valuable collections made by Mr. E. H. 
Wilson, were purchased of Prof. C. S. Sargent. 
A notable collection of cryptogams, numbering about 10,000 speci- 
mens, largely obtained by the late Mr. John B. Leiberg while engaged 
in field work in the western United States, was received as a gift from 
Mrs. Leiberg, of Leaburg, Oreg. It contains many duplicates which | 
will be available for distribution as soon as the species have been fully 
identified. An important addition from a region not well represented 
in the herbarium consisted of 1,100 plants from Venezuela, of which 
300, chiefly from the high mountains of that country, were purchased 
of Mr. Alfredo Jahn, Caracas, while the remainder, presented by 
Mr. H. Pittier, were secured by him in the course of an investigation 
of the agricultural resources of Venezuela. From the Bureau of 
Science at Manila 1,746 specimens were obtained in exchange, nearly 
1,000 of these having come from Guam, and being duplicates of mate- 
rial which had served as the basis of an extensive report on the flora
