REPORT OF THE SECRETARY 23 
specimens received for identification in the past, Mr. Killip assembled 
much valuable data for the proposed “Flora of Colombia.” 
Philip Hershkovitz, holder of the Walter Rathbone Bacon Scholar- 
ship for 1941-43, returned from Colombia in October, after an absence 
of almost 2 years. The collection he amassed forms the largest single 
accession of mammals received by the Museum during the past 25 
years. 
Under the W. L. Abbott fund, M. A. Carriker, Jr., continued 
ornithological field work in Colombia until October. He brought to 
the Museum the results of two seasons’ work, one of the finest collec- 
tions of birds that has ever been made in that area. 
Dr. Remington Kellogg, curator of mammals, served as chairman 
of the American delegation to the International Conference on the 
Regulation of Whaling held in London during January. Between 
sessions of the conference he studied at the British Museum in prepara- 
tion of a report on the recent porpoises. Dr. Kellogg spent part of 
September at the Museum of Comparative Zodlogy examining a col- 
lection of cetacean remains from Polk County, Fla. Also, at the re- 
quest of the National Research Council, for the Board for the Co- 
ordination of Malarial Studies, in collaboration with Major E. A. 
Goldman of the Fish and Wildlife Service, Dr. Kellogg prepared 
the first of a series of descriptive accounts of the kinds of monkeys 
that may carry malarial infections. 
The curator of birds, Dr. Herbert Friedmann, completed part 10, 
the gallinaceous birds, of Ridgway’s unfinished monograph, “The 
Birds of North and Middle America,” and began the revision of his 
own previously completed manuscript on the falconiform birds. 
H. G. Deignan, associate curator of birds, completed his monograph 
on “The Birds of Northern Thailand,” now in press. 
The associate curator of reptiles, Dr. Doris M. Cochran, reports 
further substantial progress in her studies on South American frogs. 
She also undertook to expand her popular handbook on “Poisonous 
Reptiles,” Number 10 of the Smithsonian War Background Studies, 
into a treatise on “Dangerous Reptiles,” nonpoisonous, as well as poi- 
sonous, for the general appendix to the Smithsonian Annual Report. 
Dr. Paul Bartsch, curator of mollusks, has worked in close coopera- 
tion with a special committee of the National Research Council, in 
preparing a list of known or suspected molluscan intermediate hosts 
of human parasites. 
In connection with the preparation of survivor manuals, Dr. L. P. 
Schultz, curator of fishes, and Earl D. Reid, scientific aid, demonstrated 
to members of the U. S. Navy the use of derris root for securing 
fish for food in emergencies.
