 and Dr. A. G. Huntsman, of the University of Toronto, compound 

 ascidians. The loans made to assist in investigations other than for 

 the Museum comprised specimens of bryozoans, sent to Mr. H. T. 

 White, of Sudbury, Canada; Philippine sea urchins of the family 

 Cidaridge, sent to Dr. Th. Mortensen, of the Zoological Museum, 

 Copenhagen, Denmark; shrimps of the family Atyidse, sent to Prof. 

 E. L. Bouvier, of the Museum d'Histoire Naturelle, Paris, France; 

 crayfishes, sent to Prof. H. Garman, of the State University of Ken- 

 tucky; and specimens of the family Pontoniidse of crustaceans, 

 sent to Dr. L. A. Borradaile, of Selwyn College, Cambridge, England. 



Plants. — The total number of specimens acquired by the division 

 of plants was approximately 140,000, of which about 80,000 were 

 comprised in the collection of grasses, forming part of the National 

 Herbarium, which had long been cared for and received its main 

 growth in the Department of Agriculture, and which during the year 

 was transferred to the custody of the Museum. Other grasses to the 

 number of about 12,800 were obtained by purchase. They com- 

 posed the private collection of Prof. A. S. Hitchcock, containing, 

 besides specimens gathered by Prof. Hitchcock and Mrs. Agnes 

 Chase, a large amount of material formerly belonging to Prof. F. L. 

 Scribner, and the types of over 200 species first described by him. 

 Through these additions the grass collection now brought together 

 in the division of plants becomes the largest and most comprehensive 

 one in this country. 



Another noteworthy accession was the herbarium of Prof. E. O 

 Wooton, consisting of about 10,000 specimens mostly from New 

 Mexico, to which a particular value attaches because of the fact that 

 much of the material, obtained in many and often remote parts of 

 the State, was not gathered in dupUcate, on which account the col- 

 lection furnishes the only means of substantiating the records of a 

 large number of species. A set of 621 specimens, of which about 

 one-third are cotypes, from the Schomburgk collection of British 

 Guiana plants, received in exchange from the British Museum of 

 Natural History, forms an especially desirable acquisition, in view 

 of the active botanical investigations recently conducted in Panama,
