REPORT OF NATIONAL MUSEUM, 1921. 53 
exchange with the Indiana University Museum 250 specimens col- 
lected by the Irwin expedition to Chile and Peru, 1918-19, were 
acquired. The Smithsonian African expedition brought 48 speci- 
mens from Lake Taganyika, with at least 2 noteworthy additions to 
our collection. An interesting lot of 10 specimens of fishes, among 
which several new species, killed by a lava flow irom Mauna Loa, 
Hawaii, into the ocean was presented by Dr. David Starr Jordan. 
They were collected by Tom Reinhardt and Carl S. Carlsmith about 
October 6, 1919. 
Insects.—Several important collections made by private individuals 
have been donated during the present year. Among them the J. P. 
Iddings collection of butterflies and moths, presented by the heirs of 
Doctor Iddings, is in a way unique, since all the 2,500 named speci- 
mens, mostly from the Tropics, especially of the oriental region, were 
mounted in Riker and similar mounts ready for exhibition. They 
were at once placed in suitable cabinets, but the final arrangement and 
labeling are still in progress. Another collection of Lepidoptera, con- 
sisting of about 5,000 specimens, was donated by Mr. B. Preston 
Clark. The W. D. Richardson collection of Coleoptera, about 4,350 
specimens, was presented to the Museum by the collector. Another 
welcome gift consisted of about 2,000 specimens of miscellaneous Phil- 
ippine insects, chiefly Hymenoptera, from Dean C. F. Baker, Los 
Bafios, P. I. Another noteworthy acquisition relates to the class 
Protura, animals similar to a very primitive wingless type of insects, 
but without antenne. Of this group, of which only 26 species are 
known in the world, 12 species, 11 new, collected and described by 
Dr. H. E. Ewing, were donated by him. It should finally be men- 
tioned that Mr. William Schaus, of the Bureau of Entomology, and 
an honorary assistant curator in the division of insects, has continued 
to make gifts of Lepidoptera from his private collection and by pur- 
chase, and has also donated much material which he has received from 
other lepidopterists by exchanging portions of his own collection 
with them. He has also purchased water-color paintings of more than 
50 rare butterflies and donated them to the collection. 
Marine invertebrates—As usual, the Bureau of Fisheries was the 
largest single contributor, the principal accession being some 360 
lots of sponges collected by the Fisheries steamer Albatross in 1902 
(Hawaii) and 1904-5 (eastern Pacific) estimated at comprising 
more than a thousand specimens. These were included in the ship- 
ment from Prague by Doctor Trojan. They had originally been 
transmitted to Doctor von Lendenfeld by the bureau direct. Among 
the other specimens transferred by the Bureau of Fisheries may be 
noted a rather complete series of juvenile stages in the life history of 
Ueca pugilator, one of the east-coast fiddler crabs, through Mr. 0. W.
