Mr. Sclati:r read an extract from a letter received from 

 ]Mr. Graham Kerr, dated Waikthlatimungyalwa, in the 

 Cliaco Boreal of Paraguay (lat. 23° 30' S. approx.), in which 

 he stated that his time had been fully occupied since he had 

 arrived there (from Concepciou) with researches upon 

 Lepidosiren, which was very abundant. He had, however, 

 observed many birds, amongst which were Tardus rufiventris, 

 Polioptila dumicola, Tanagra sayaca, Saltator ccerulescens, 

 S. aurantiirostris , Molothrus badius, Agelaus ruficapillus, 

 A. cyanopus, Tmniopttra nengeta, T. irupero, Machetornis 

 rixosa, Hapalocei'cus flaviventris, Leuconerpes Candidas, 

 Colaptes agricoia, Picas cactorum, Rhamphastos toco, Co- 

 nurus acuticaudatus, C. nanday, Pyrrhura vittata, Urubitinga 

 zonura, Cathartes atratus, Ortalis canicollis, and Cariama 

 cristata, besides many others, and numerous Herons and 

 Ducks. After the pressing work of collecting specimens 

 of the Lepidosiren was over, he proposed to make some 

 bird-skins, but, on the whole, the avifauna here appeared 

 to be poorer than on the Pilcomayo. 



Mr. ScLATER exhibited a specimen of a new Paradise-bird 

 sent to be figured in ' The Ibis ' by Mr. De Vis, and proposed 

 to be named Macgregoria pulchra. It had large eye-wattles 

 like Paradigalla carunculata, but quite different in shape, and 

 the front was not naked, but covered with erect bristles. This 

 species had been discovered by Sir William Macgregor on 

 Mount Scratchley during his recent expedition across British 

 New Guinea at an altitude of from 10,000 to 12,000 feet. 



^ Mr. ScLATER exhibited a drawing, by Mrs. Frederick 

 ^^ hite, of Georgetown, British Guiana, representing the nest 

 and egg of the Demeraran Cock-of-the-Rock, Rupicola 

 crocea, of natural size, being one of the specimens obtained 

 by Mr. C. A. Lloyd on the Pizara River (see ' The Ibis,' 

 1896, p. 429, quoted from ' Timehri ') . Mr. Sclater observed 

 that the egg of Rupicola peruviana had been described and 

 figured by Goudot (Mag. de Zool. 1843, Ois. pi. 37) and by 

 Salmon (P. Z. S. 1879, p. 519), but that he was not 

 acquainted with any previous information as to the nesting
