L18T OF BIRDS COLLECTED BY W1LLL\M T. FOSTER IN PARAGUAY. B}^ Hakky C. Oberholser, Assistant Orriitliohxjist, Depaiinieiit of Agriculture. The collection of Parao-iui}-birds .sent by Mr. AVilliani T. Foster to the United States National Museum, though small, is of more than casual interest. It consists of 78 specimens, representing 65 species and subspecies, several of which appear to be heretofore unrecorded from Paraguay; while BJac/cxs jjileatus^ Myiopagis caniceps^ Phyllo-iinjiax .s((l rtidorii, and (Ujanocordx hecJcelii are of sufficient rarity to be w^orthy of special mention. Further than this, there are seven })irds (four species and three subspecies) that seem to be new to science; and of these preliminary descriptions have already been published.^ Matter between quotation marks in the following list is from the notes of the collector. Sapucay, Paragua}^, whence come these specimens, is situated a short distance east of the cit}^ of Asuncion, thus somewhat south of the central portion of the countr}'. The subjoined notes are presented at the instance of Mr. Ridgway, curator of the division of 1)irds, to whom and to Dr. Charles W. Richmond the writer it5 indebted for man}^ kindnesses. To the authorities of the American Museum of Natural History, for the loan of specimens, due acknowledgment should here be made. Family BUCCONID.E. BUCCO CHACURU Vieillot.

In this species there seems to be much individual difference in the depth of the buffy tinge on the lower surface and on the collar; in some specimens these parts are almost pure white, in others deep ochraceous. iProc.
