120 REPORT OF NATIONAL MUSEUM, 1914. 
collected by the Secretary, which, though containing no types, are 
most valuable as additions to the reserve and exhibition series. A 
second important lot of types, consisting of 150 specimens of Silu- 
rian Bryozoa and Ostracoda, was the result of a study, by the curator 
of the division, of the Yale University collections from the island of 
Anticosti, and were presented in the name of the Peabody Museum 
of Natural History. Still another series of types, represented by 
25 specimens of “'vogyra, described and figured by Mr. L. W. Stephen- 
son in Professional Paper No. 81, of the Geological Survey, was 
deposited by the Survey. Other accessions from the Survey included 
a collection of Carboniferous invertebrates from the Manzano group 
of New Mexico, described by Dr. George H. Girty in Survey Bul- 
letin 889; a single specimen, deserving mention from the fact that it 
is a figured echinoid from the Miocene of California; and some 30 
slabs of shale containing numerous well-preserved fossil insects ob- 
tained in the Green River formation of eastern Utah by Mr. E. G. 
Woodruff. 
About 38,000 specimens of Paleozoic fossils from various locali- 
ties in Canada were received as a gift from Dr. E. O. Ulrich, of 
Washington, by whom they were collected during field work in the 
summer of 1918. They are particularly valuable as they were se- 
lected with special reference to the needs of the Museum, and certain 
early Silurian faunas in Ontario are well represented. <A series of 
Tertiary mollusks and Ordovician graptolites from Australia con- 
stitute an important exchange from Mr. James Hay Young, of Mere- 
dith, Victoria. The graptolites have proved excepticnally interest- 
ing for comparison with American species, as their study has shown 
the identity of numerous species in these two widely separated areas. 
Owing to the greatly increased subdivision of the geologic time 
scale, resulting from recent active work in stratigraphic geology and 
paleontology, it has become necessary to register and locate the col- 
lections of invertebrate paleontology in greater detail than was 
previously customary. While this requirement entails much addi- 
tional labor, especially as regards the older collections, excellent prog- 
ress has been made with the Cambrian, Mesozoic, and Cenozoic ma- 
terial, and the work is well under way with the general Paleozoic col- 
lections. The preparation and installation of the Cambrian collec- 
tions has been rapidly advanced, as Secretary Walcott was able dur- 
ing last year to give more of his time than usual to its supervision. 
One of the results was that many of the faunal series previously 
filling a large number of drawers have, through the process of mak- 
ing them ready for study, been so reduced in bulk as to occupy a 
minimum amount of space. Of particular importance has been the 
accurate location in the Cambrian period of the numerous faunas 
from the upper Mississippi Valley. Through the efforts of the
