REPORT OF NATIONAL MUSEUM, 1914, 125 
corrected, and the new materials described. A report upon this in- 
vestigation remains to be submitted. Dr. O. P. Hay, who is en- 
gaged, under the Carnegie Institution of Washington, in the study 
of the vertebrate animal life of the North American Pleistocene 
period, was furnished, as heretofore, with accommodations for his 
work in the National Museum. Up to the present time his atten- 
tion has been mainly directed to the larger land mammals, and pri- 
marily to a correct determination of the species found and their rela- 
tion to the various divisions of the Pleistocene, as now recognized. 
In furtherance of this research he has studied the Museum collec- 
tions as well as those elsewhere available, and is preparing important 
papers, accompanied by maps, showing the geographical distribu- 
tion of all reported finds, some of which have already been published. 
Paleobotany—Three valuable type collections of fossil plants were 
received from the Geological Survey, as follows: About 150 speci- 
mens from Cape Lisburne, Alaska, obtained by Mr. Arthur J. Col- 
lier in 1904 and described by Dr. F. H. Knowlton; 168 specimens 
from the Tuscaloosa formation of Alabama, described by Mr. E. W. 
Berry; and a series of Cretaceous and Tertiary forms from South 
Carolina and Georgia, described by Mr. Berry. Another accession, 
comprising 45 specimens of fossil wood from the Leeward Islands, 
collected by the Geological Survey and the Carnegie Institution of 
Washington during joint field work, was acquired by transfer from 
the former and as a gift from the latter. 
The most important work of the year was the completion of a 
card index of the Mesozoic and Cenozoic plants, which required the 
detailed overhauling of over 2,500 drawers of specimens, by Mr. 
T. E. Williard, of the Geological Survey, under the direction of Dr. 
F. H. Knowlton. With the preparation of a similar catalogue of 
the Paleozoic plants during the previous year, under Mr. David 
White, it is now possible to locate any parts of the paleobotanical 
collections without delay. Moreover, no fossil plant material re- 
mains in storage. 
Dr. Arthur Hollick, of the New York Botanical Garden, spent 
over two months in a continuation of his studies on the Cretaceous 
and Tertiary floras of Alaska, while Dr. E. W. Berry, of Johns 
Hopkins University, was engaged in paleobotanic researches cover- 
ing the Upper Cretaceous and Eocene strata of the Atlantic Coast 
Plain. Both of these pieces of work, which are being based on the 
Museum collections, are so extensive that several years will be re- 
quired for their completion. 
Exhibition collections—F¥or the display of new accessions of im- 
portant mineral specimens, awaiting opportunity for their proper 
assignment, a Kensington case was provided near the east end of 
the mineral hall, and it will be possible to keep it approximately
