SECRETARY’S REPORT RZ 
about 8,800 Pacific invertebrates came from the Naval Medical Re- 
search Unit No. 2; and about 6,000 from the Navy’s Second (1948) 
Antarctic Development Project. 
Outstanding among the year’s molluscan accessions were 8,000 speci- 
mens from Cocos-Keeling Island; 9,000 from Bikini, Rongerik, and 
Johnston Islands, collected by members of the staff during the Bikini 
Scientific Resurvey ; a large number from various other Pacific islands; 
and about 1,500 Antarctic marine mollusks. The Navy Antarctic Ex- 
pedition yielded also about 500 echinoderms. 
Botany.—Several unusually large plant accessions came to the Na- 
tional Herbarium. Among these was the bequest of 5,000 specimens of 
fungi, the herbarium of the late William H. Long, of Albuquerque, 
N. Mex. H. A. Allard collected 9,100 plants for the Museum in the 
Dominican Republic. An unusually interesting lot of Colombian 
plants came from the collector Oscar L. Haught, and collecting work 
of E. C. Leonard, a member of the staff, yielded 1,900 bryophytes from 
the Patuxent Wildlife Research Refuge, Maryland. In addition, 
many hundreds of desirable plant specimens and photographs were 
obtained by exchange or purchase. 
Geology.—The general mineralogical collections continued to grow 
through gifts, exchanges, and purchases, and as usual the year’s acces- 
sions in this field included several new species of minerals. The out- 
standing addition to the gem series was an Arabian stallion head 
carved in turquoise by Oscar J. W. Hansen. Five meteorites not 
previously represented in the department’s collections were received 
by gift, and excellent additions to the ore collections came from many 
sources. Rock specimens received contained important described 
material. 
Many important specimens of fossil invertebrates came to the 
Museum as gifts, four of the larger lots being 2,000 Ordovician fossils 
from Minnesota; 1,700 Mesozoic and Tertiary fossils from Cuba; 
15,000 Devonian and Upper Paleozoic fossils from Nevada; and 
1,700 Jurassic brachiopods and mollusks from the vicinity of the 
Smithsonian’s Astrophysical Observatory station at Calama, Chile, 
collected by Miss Jessie G. Beach, of the department staff, while on 
vacation. Through the Walcott funds there were received 900 speci- 
mens of various invertebrates from the famous Permian deposits of 
Sosio Valley, Sicily; 2,500 from the Devonian of Ontario; 50,000 
Paleozoic fossils collected by Dr. A. R. Loeblich, Jr., of the staff; and 
15,000 Middle-Upper Paleozoic and Cretaceous fossils collected by 
Curator G. A. Cooper and Elias Yochelson. Several large transfers 
of specimens came from the United States Geological Survey. 
This was a banner year for the division of vertebrate paleontology, 
the greatest number of specimens being added to the collections since 
the field season of 1931. The outstanding acquisition was the skull,
