ZOOLOGICAL SERIES OF FIELD MUSEUM OF NATURAL HISTORY Volume 24 CHICAGO, NOVEMBER 26, 1943 No. 33 BIRD LICE FROM THE TINAMIDAE BY THERESA CLAY DEPARTMENT OF ENTOMOLOGY, BRITISH MUSEUM (NATURAL HISTORY) The species of Mallophaga described by Rudow from Nothura boraquira Spix (= Tinnamus bannaquira of Rudow) have caused diffi- culty owing to the fact that Rudow's original material has been lost and no subsequent author has examined material from the type host. In 1939, while on a visit to the United States, Colonel Meinertz- hagen and I secured four species of Mallophaga from specimens of Nothura boraquira in the collection of Field Museum of Natural History. As a consequence, I am able, in this paper, to make some contribution to the elucidation of Rudow's species. Descriptive and synonymical notes on other Mallophaga from Tinamidae are included. Acknowledgment is due Mr. Rudyerd Boulton, Curator of Birds, for his kind co-operation in making the material available for study, and Mr. Clifford C. Gregg, Director of Field Museum, for providing publication facilities. In considering Rudow's descriptions it must be remembered that these tend to be somewhat inaccurate, as can be shown by compar- ing them with the descriptions and figures made by Taschenberg (1882) from Rudow's specimens. Hopkins (1940, p. 418) has also shown that the measurements given by Rudow cannot be taken into consideration, as they seem to have little relation to reality and appear to be the "wildest of guesses." As the majority of Rudow's specimens have been lost, it is important to fix his names definitely to the species from the type hosts which follow the descriptions most closely, even though there are apparent discrepancies. It cannot be emphasized too strongly that once these names have been fixed it is in the interests of all to adopt the usage of the names even if there are differences of opinion over the interpretation of the original descriptions.
