tory) in London, and had an excellent opportunity to study important 
historic collections in the field of his speciality. 
In addition to participating in the Smithsonian-Bredin Caribbean 
Expedition discussed earlier, Dr. Thomas E. Bowman, associate 
curator of marine invertebrates, visited Puerto Rico for 2 weeks in 
early April 1959, at the request of Dr. Robert M. Coker, who is 
directing a study of the zooplankton of the bays along the south- 
western coast. With headquarters at the Institute of Marine Biology, 
Dr. Bowman made extensive collections that will materially assist 
him in his project of identification of the copepods of the region. 
Dr. Harald A. Rehder, curator of mollusks, spent the week of 
February 16-23, 1959, in Florida, primarily to act as one of the judges 
of the annual show of the St. Petersburg Shell Club. The Smith- 
sonian Institution offers an annual award for the best exhibit in this 
show. Subsequently he visited the Marine Laboratory of the Uni- 
versity of Miami, where he observed some of the current studies of 
staff members of level bottom marine invertebrate communities along 
the south Florida coast. 
Dr. G. A. Cooper, head curator, department of geology, accom- 
panied by Dr. Richard S. Boardman, associate curator of invertebrate 
paleontology and paleobotany, spent the period May 18-30, 1958, on a 
field trip to central New York. They were accompanied by Dr. Ger- 
trude Biernat, of Polska Akademia Nauk, Zaklad Paleozoologii, 
Warsaw, Poland, a visitor to the museum for several months, and 
by two members of the Geological Survey staff. They spent several 
days studying and collecting from the type section of the Hamilton 
group of the Devonian, which extends from Stockbridge Falls on 
the north to North Norwich on the south. The party was joined by 
other geologists, including Dr. Paul Sartenaer, of Belgium, and mem- 
bers of the staff of the New York State Museum, and with this com- 
pany a study of the facies changes which take place in the Tully 
formation was made. Subsequently sections were examined in the 
area of Cooperstown, Cobleskill, Albany, Kingston, N.Y., and 
Stroudsburg, Pa. Following this trip Dr. Boardman spent a few 
days at the New York State Museum at Albany to investigate the 
possibility of identifying bryozoan fragments in well cuttings in the 
Middle Devonian in New York State. 
During August 1958 Dr. George Switzer, curator of mineralogy 
and petrology, made an extended collecting trip to western localities, 
particularly to various individuals and well-known localities in Iowa, 
Colorado, New Mexico, California, and Montana. He obtained much 
material of value to the Smithsonian for purposes of study or exhibit. 
Accompanied by Paul E. Desautels, associate curator of mineralogy 
and petrology, Dr. Switzer made several other trips for the purpose
