REPORT OF THE SECRETARY 25 
The most important additions to the gem collection came as trans- 
fers from the Procurement Division of the Treasury Department. 
They include a large blue topaz, three fine aquamarines, an amethyst, 
and a tourmaline. Other outstanding gems were procured through 
the Canfield, Roebling, and Chamberlain funds. 
The following were noteworthy additions to the collections of fossil 
invertebrates: 367 type specimens of Middle Cambrian brachiopods 
and trilobites from Montana; 425 Middle Ordovician specimens from 
the unique cryptovolcanic structure at Kentland, Ind.; 750 bryozoans, 
corals, and other classes from the Middle Ordovician of Virginia and 
Tennessee ; and 700 Devonian brachiopods from southwestern Ontario. 
From the Upper Paleozoic rocks donations included 180 Pennsy]- 
vanian and Permian gastropods from New Mexico, 500 Pennsyl- 
vanian fusulines, about 5,000 Pennsylvanian fossils from near St. 
Louis, Mo., and 250 from near Moab, Utah. Gifts through the 
Springer and Walcott funds added other worthy Paleozoic fossils, 
including 2,100 Cenozoic mollusks from the Lord Calvert collection. 
Field trips conducted under the Walcott fund by Curator G. A. 
Cooper and his associates resulted in about 5,000 specimens of Ordo- 
vician invertebrates from Alabama, Georgia, Tennessee, and Virginia, 
a similar number from the Mississippian and Pennsylvanian rocks 
of central Texas, and an equally large lot of Upper Paleozoic fossils 
from west and central Texas, together with 400 blocks from west 
Texas containing silicified fossils for etching. The division also 
received 3,500 slides of Cretaceous Foraminifera from Arkansas and 
50 from Peri. Other gifts included important Cenozoic material, for 
example: 4,000 fossil fresh-water shells, 1,070 Tertiary fossils, and 
about 75 Pleistocene fresh-water gastropods from Utah. Important 
collections transferred from the United States Geological Survey 
comprised about 3,700 types of Carboniferous and Permian fossils 
described by the late Dr. George H. Girty; 200 Jurassic invertebrates 
from Wyoming; 585 Cretaceous ammonites from Wyoming; and 1,000 
Devonian and Mississippian fossils from the Central Mineral Region 
of Texas. In addition, several hundred specimens were received by 
exchange with other institutions and individuals. 
In the division of vertebrate paleontology there was a decrease 
of material coming in, owing largely to the fact that no expeditions 
to obtain fossil vertebrate specimens could be sent out until just before 
the year’s end. The extreme rarity of fossil bird remains made note- 
worthy the gift of vertebrae, mandibles, and other bones of the double- 
erested cormorant Phalacrocorax auritus from Pleistocene deposits 
in Florida. Five fossil examples of the puzzling egg capsules of 
chimaeroid fishes from the Upper Cretaceous rocks of México and
