graphical survey of the British Columbia and Alberta boundary line 

 and the Mount Kobson region. The expedition, which consisted of 

 four members, including Mr. N. Hollister, in charge, and Mr. J. H. 

 Riley, aid in the division of birds, was absent from June until Octo- 

 ber, and succeeded in obtaining a fairly complete collection of the 

 mammals and birds of this previously unworked territory, together 

 with many insects and plants, all of which were turned over to the 

 National Museum. 



Reference was made in tlie last report to the biological survey of 

 the Panama Canal Zone initiated by the Smithsonian Institution 

 and carried on with the cooperation of several of the departments of 

 the Government. The work was continued during the past year and 

 resulted in important additions to the collections, especially of fishes, 

 insects, aquatic invertebrates, and plants. 



By invitation of Dr. A. G. Mayer, director of the marine biological 

 station of the Carnegie Institution of Washington at the Dr}^ Tor- 

 tugas, Fla., Dr. Paul Bartsch, assistant curator of mollusks, was de- 

 tailed to accompany an expedition to the Bahama Islands in the 

 steamer Anton Dohrn for the purpose of obtaining a representative 

 series of marine invertebrates for the exhibition collections of the 

 Museum. With headquarters at the junction of the South Bight and 

 Tongue of the Ocean, explorations were carried on in the neighboring 

 region for about one month, after which a trip was made from 

 Miami to Key West, Fla., stopping at manj^ points on the way. The 

 results were entirely satisfactory, color notes were made on the 

 various marine species collected, and several thousand land shells as 

 well as many specimens of reptiles and batrachians were also secured. 

 Mr. John B. Henderson, jr., a regent of the Smithsonian Institution 

 and long associated with the division of mollusks of the Mubcum, 

 to which he has been a liberal contributor, made a dredging cruise 

 with his yacht Eolis to the Bahama banks and the region oil' Miami, 

 Fla., during the spring of 1912. The work extended to a depth of 60 

 fathoms, and furnished a rich collection of marine invertebrates 

 which has been generously shared with the Museum. 



Mr. P. C. Standley, assistant curator of plants, was engaged dur- 

 ing two weeks of the summer of 1911 in botanical collecting in New 

 Mexico, chiefly along the northern boundary of the State and in the 

 Navajo Reservation. He preserved about 2,800 specimens, many of 

 which represent species not previously known from New Mexico, and 

 secured much information relating to the distribution of the species 

 in that region. 



Miss M. J. Rathbun, assistant curator of marine invertebrates, ac- 

 companied by Miss Violet Dandridge, artist, spent the month of 

 August at the Marine Biological Station, Harj^well, Me., and the sta- 

 tion of the Bureau of Fisheries, Woods Hole, Mass., for the purpose
