for at the Hygienic Laboratory of the Bureau of Public Health and 

 Marine-Hospital Service, the Bureau of Animal Industry, and the 

 Naval Medical School. The additions during the year, which were 

 numerous, were in part collected by officers and members of these 

 services and in part received as gifts and exchanges. Among the out- 

 side contributors were Mr. C. W. Howard, of the Department of 

 Agriculture of Portuguese East Africa ; Prof. A. Railliet, of Alf ort, 

 France ; Dr. R. P. Strong, of the Bureau of Science, Manila ; Dr. 

 Bell, of Hongkong, China; Dr. Paul R. Stalnaker, passed assistant 

 surgeon, United States Navy, Culebra, Porto Rico; Capt. J. F. 

 Siler, United States Army, Post-Graduate School, New York; and

Investigations on material added to the collections were completed 

 and published on the following subjects: The taxonomic value of the 

 microscopic structure of the stigmal plates in the tick genus Der- 

 macentor, by Dr. Charles Wardell Stiles; some known and three new 

 endoparasitic trematodes from American fresh-water fish, some new 

 parasitic trematode worms of the genus Telorchis, and a new trema- 

 tode {Styphlodora bascaniensis) with a blind Laurer's canal, by 

 Mr. Joseph Goldberger; a new species of AthesmAa (A. foxi) from a 

 monkey, by Mr. Joseph Goldberger and Mr. Charles G. Crane ; a new

Plants. — The total number of specimens of plants received during 

 the year was 38,716, of which nearly one-third were obtained in con- 

 nection with the biological survey of the Panama Canal Zone now 

 being conducted under the auspices of the Smithsonian Institution, 

 as described elsewhere. The collections transferred by the Bureau 

 of Plant Industry, the Biological Survey and the Bureau of Ento- 

 mology of the Department of Agriculture aggregated 6,541 speci- 

 mens, and by the Bureau of Fisheries, 1,700 specimens. Private col- 

 lectors presented 2,390 specimens, while 8,740 were obtained through 

 exchange, principally from the Bureau of Science at Manila, the New 

 York Botanical Garden, and the Yale University Forest School. 

 The number of specimens purchased was 5,900. 



It is gratifying to note that in connection with the changes made 

 possible by the completion of the new building this division has been 

 able to secure convenient quarters with ample space for the growth 

 of some years to come. To this purpose has been allotted the entire 

 upper story of the main part of the Smithsonian building, formerly 

 occupied by the exhibition collections of prehistoric archeology. It 

 consists of a single large hall, 200 feet long, 50 feet wide and 29 feet 

 high, in which 12 rooms for laboratory and office purposes have been 

 screened off at one end. The rest of the hall furnishes accommoda-
