40 REPORT OF NATIONAL MUSEUM, 1906. 
in beetles. The Eumenide were examined by the Rev. F. W. X. 
O’Brien, S. J., who contemplates writing a synopsis of the North 
American species. 
The investigations conducted, in connection with the division of 
marine invertebrates were extensive and important. The soundings 
made by the U. 8. 8S. Vero during the survey for a trans-Pacific cable, 
rich in specimens of foraminifera, were examined and reported on by 
Dr. James M. Flint, U. S. Navy, curator of medicine, in ‘‘A Contribu- 
tion to the Oceanography of the Pacific,” constituting Bulletin No. 55 
of the Museum. Dr. James E. Benedict, assistant curator of marine 
invertebrates, studied the anomuran crabs from Hawaii and Japan, 
and, in cooperation with Dr. Harriet Richardson, made considerable 
progress toward completing his work on the family Lithodidee, 
including a revision of the genera. Miss M. J. Rathbun, also assist- 
ant curator of the division, finished the second part of her monograph 
on the fresh-water crabs of the world, which was published by the 
Museum of Natural History, Paris, France. She reported on the 
brachyuran and macruran crustaceans obtained during the Hawaiian 
investigations of the U.S. Bureau of Fisheries, began the working 
up of the decapod crustaceans from several cruises of the steamer 
Albatross in the tropical Pacific and of the general collection of grap- 
soid crabs, and prepared a paper on certain New England crustaceans. 
A monograph of the isopod crustaceans of North America by Dr. Har- 
riet Richardson, collaborator, based chiefly on the Museum collection, 
was published as Bulletin No. 54 of the Museum. It treats of 369 
species, 12 of which, together with 9 genera, were new to science. 
The same author also contributed a paper on the family Spheromide 
and one descriptive of a new genus of Isopoda from the <Adbatross- 
Agassiz Pacific expedition of 1904-5. Dr. 'T. W. Vaughan, custodian, 
reported on the stony corals from the same cruise of the Adbatross 
and from the explorations at the Hawaiian Islands by the Bureau of 
Fisheries, and, in two papers, described several new species belonging 
to the genera Hungia, Caenocyathus, and Astrangia. 
Reports upon material collected in Hawaiian waters by the Bureau 
of Fisheries were published during the year as follows: On the star- 
fishes by Mr. W. K. Fisher, on the nemerteans by Prof. W. R. Coe, 
on the annelids by Mr. A. L. Treadwell, on the hydroids by Prof. C. C. 
Nutting, and on the medusze by Dr. A. G. Mayer. Descriptions of 
the parasitic J/yzostoma taken from the crinoids collected on the Japan 
coast by the same Bureau were published by Mr. J. F. McClendon, 
who also examined the general collection of crinoids in the Museum 
for additional specimens. The following papers based upon material 
from <A/batross explorations in the tropical Pacific under the direction 
of Dr. Alexander Agassiz, in addition to those mentioned above, were
