proved by Brehm, Homeyer, Kleinschmidt, and others); and 

 as the eggs of C. brachijdactyla were mostly, though not always, 

 more thickly blotched, they would at present better stand as 

 species than as subspecies, until it might turn out that they 

 intergrade completely in certain places. The British bird 

 was C. hrachydactyla in a slightly differentiated form, and 

 C. familiaris did not seem to occur in England at all. 



Mr. ScLATER read an extract from a letter received from 

 Mr. Graham Kerr, dated Waikthlatimungyalwa, in the 

 Chaco 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 Concepcion) with researches upon 

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

 observed many birds, amongst which were Turdus rufiventris, 

 Polioptila dumicola, Tanagra sayaca, Saltator ccerulescens, 

 S. aurantiirostris, Molothrus badius, Agelaus mficapillus , 

 A. cyanopus, T(Enioptera nengeta,, T. inipero, Machetornis 

 rixosa, Hapalocercus flaviventris, Leuconerpes candidus, 

 Colaptes agrtcola, Picus cactorum, Rhamphastos toco, Conu- 

 rus acuticaudatus , C. nanday, Pyrrhura vittata, Urubitinga 

 zonura, Cathartes atraius, 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 Pilcoraayo. 



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

 sent to be figured in ' The Ibis ' by Mr. De Yis, 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.
