REPORT OF NATIONAL MUSEUM, 1910. 35 
previously described, representatives of all of which were donated by 
him to the Museum. The Geological Survey of Canada, through Dr. 
John Macoun, contributed a series of mollusks, including cotypes of 16. 
new species, dredged in Barclay Sound, Vancouver Island. Types of 
new species and other specimens from the coast of California were 
presented by Miss J. M. Cooke, Dr. Fred Baker, Mr..C. W. Gripp, Mrs. 
E. E. Johnston, and Dr. R. H. Tremper. Mr. and Mrs. T.S. Oldroyd, 
of California, long-time contributors to the Museum, transmitted very 
acceptable material at various times during the year. A miscellane- 
ous collection of shells, chiefly European, was received from Lieut. 
Col. L. Worthington Wilmer, of Ryde, England, to whom the Museum 
has also become indebted for many past favors. 
The entire collection of the division of mollusks, to which the 
third story of the west range had been assigned, was moved to the 
new building in August, 1909. The study or reserve series has 
already been arranged in new metal cases specially constructed 
for the purpose, but the exhibition series remains in the condition 
as transferred, awaiting the determination of a plan for its enlarge- 
ment and installation on a more comprehensive basis than hereto- 
fore. 
About 5,300 lots of specimens were catalogued, labeled, and added 
to the reserve series. The Philippine collection, mainly from the 
Albatross explorations of 1910, is gradually being cleaned and made 
teady for study, and much progress has been made in preparing 
the west American material with the view of monographing the 
fauna. In the preliminary work of sorting the dry Philippine 
specimens about 29,000 labels were written. From deep sea dredg- 
ings, chiefly by the vessels of the Bureau of Fisheries, there has 
accumulated a large amount of fine material from the ocean bottom 
in different parts of the world. While consisting chiefly of the 
remains of the lowest forms of life, such as foraminifera, this material 
also contains immense numbers of smal] and even minute mollusks. 
The sorting out of the specimens is a slow and tedious task, in which 
something has been done from year to year. With special assistance, 
however, 90 lots of the material were completely and carefully 
gone over during the past year, with the result of obtaining not 
less than a quarter of a million specimens, representing a great 
number of interesting and mostly new species. Many specimens 
of mollusks from the western coast of America as far north as Alaska, 
principally obtained during the expeditions of the steamer Albatross 
and those of Dr. Dall, were cleaned and prepared for incorporation 
in the study series of dried specimens. About 8,000 catalogue 
cards were written, representing partly the beginning of a revised 
catalogue of the reserve collection, and partly a species catalogue 
of Philippine mollusks.
