In the division of plants the following special investigations were 

 begun, continued, or completed during the year: Dr. Frederick V. 

 Coville has continued his studies in breeding and propagating the 

 blueberries {Vaccinium) and has made frequent use of the herbarium 

 as heretofore. Dr. J. N. Rose has continued his studies of the 

 Cactaceae, in collaboration with Dr. N. L. Britton, director in chief 

 of the New York Botanical Garden, work which has been under way 

 since 1911 under the auspices of the Carnegie Institution of 

 Washington. Volume 3 of The Cactaceae will probably appear in 

 July, 1922. The manuscript of volume 4 has been submitted for 

 publication. Doctor Rose has continued also his studies of Ecua- 

 dorian plants referred to in recent reports. Dr. William R. Maxon 

 has continued his studies of the pteridophyta, giving particular at- 

 tention to several large collections from Central America, the West 

 Indies, and tropical South America. Several short papers have been 

 published, but no new work other than that of identifications has 

 been undertaken. Paul C. Standley has continued the preparation of 

 a synoptical account of the flora of Central America and Panama, 

 and has spent six months in field work in Salvador, Honduras, and 

 Guatemala, collecting material for use in this connection. He has 

 begun the preparation of a list of the Salvador plants to be published 

 in El Salvador. The Flora of Alaska and the Flora of Glacier 

 National Park, mentioned in previous reports as completed, have 

 not as yet been published. Ellsworth P. Killip has continued his 

 studies of the genus Passifora and has published descriptions of a 

 number of new species of this genus from Mexico and Central 

 America. Emerj^ C. Leonard has practically completed his study of 

 the genus Scutellaria and has continued his study of the plants col- 

 lected by himself and Dr. W. L. Abbott in Hispaniola. 



Dr. O. P. Hay, of the Carnegie Institution, has made constant use 

 of the collections in connection with his work on the Pleistocene fauna 

 of North America. Remington Kellogg examined cetacean and other 

 material in connection with his studies of fossils. Charles Sheldon 

 has made a beginning at overhauling the collection of mountain 

 sheep. H. E. Ewing. of the division of entomolog}^, has collected 

 parasites from the skins in the division of mammals. Dr. H. C. 

 Oberholser, of the Biological Survey, continued his determination 

 of Malayan and other birds. Dr. A. Wetmore, also of the Biological 

 Survey, spent much time on the collection of bird skeletons. A. C. 

 Bent, Taunton, Mass., devoted two daj'S to examining various eggs 

 and birds in connection with the "Life Histories" on which he is 

 engaged. The thanks of the Museum are due to Dr. Frank M. 

 Chapman, W. E. Clyde Todd, Dr. John C. Phillips, and Dudley
