4 is well advanced. Doctor Rose has continued his studies, also, of 

 Ecuadorean plants referred to in the last report. Mr. William R. 

 Maxon, associate curator, has continued his investigation of the pteri- 

 dophyta and has prepared manuscript for Part VIII of Studies of 

 Tropical x\merican Ferns. He has nearly completed a report, also, 

 upon the large collection of Haitian ferns made by Dr. W. L. Abbott 

 and Mr. Emery C. Leonard last year and has reviewed critically the 

 West-American allies of Selaginella rupestris^ describing several new 

 species. A popular article on the botanical gardens of Jamaica has 

 been contributed to the Smithsonian Annual Report. Mr. Paul C. 

 Standiey, assistant curator, has nearly completed manuscript sum- 

 marizing his studies of the trees and shrubs of Mexico, and has sub- 

 mitted parts 2 and 3 for publication; parts 4 and 5 (conclusion) will 

 be turned in for publication during the coming year. He has recently 

 undertaken the preparation of a synoptical account of the flora of 

 Central America and Panama, based primarily upon the collections 

 in the National Herbarium, and in this connection proposes visiting 

 Salvador, in which region practically no botanical collecting has been 

 done. Mr. Standiey also has completed manuscript for the Flora 

 of Alaska. Mr. Ellsworth P. Killip, aid, has finished his revision of 

 the genus Passiflora as represented in Mexico, Central America, and 

 Panama, and the manuscript is nearly ready for publication. Mr. 

 Emery C. Leonard, aid, has continued his study of the genus Scutel- 

 laria. With the assistance of Mr. Standiey he has nearly completed 

 the identification of the phanerogams of his Haitian collection, of 

 last year. i 



Dr. C. Hart Merriam, associate in zoology, continued his study on 

 North American bears. Mr. N. Hollister has continued work on the 

 African Artiodactyla, but it is greatly delayed b}^ the housing of the 

 mammalian study series on different floors from the basement to 

 the attic. 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. The thanks of the Museum 

 are due to Mr. Oldfield Thomas, of the British Museum, for having 

 compared specimens sent to him with types and other material in 

 the collections under his care. 



Dr. W. L. Abbott, associate in zoology, made two visits to the 

 division of birds for purpose of examining material collected in 

 Haiti and Santo Domingo by him, and giving information about the 

 specimens and localities. Dr. H. C. Oberholser, of the Biological 

 Survey, continued his determination of the Malayan material col- 

 lected by Dr. W. L. Abbott, and made occasional identifications in 

 other parts of the ornithological study series. Dr. A. Wetmore, also 

 of the Biological Survey, although away from Washington most of 

 the year, spent some time in work on the bird skeletons.
