EEPOBT 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 from 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 b}^ the collector. Another 

 welcome gift consisted of about 2,000 specimens of miscellaneous Phil- 

 ippine insects, chiefly Hymenoptera, from Dean C. F. Baker, Los 

 Baiios, P. I. Another noteworthy acquisition relates to the class 

 Protura, animals similar to a very primitive wingless type of insects, 

 but without antennae. 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 invet'tehrates. — 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 

 Uca pugilator, one of the east-coast fiddler crabs, through Mr. O. W.
