and egg of the Demeraran Cock-of-tbe-Rock^ Rupicola 

 crocea, of natural size^ being one of tbe 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 peruvia7ia 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 vrith any previous information as to the nesting 

 of R. crocea, except that of Schomburgk (' Reise/ ii. p. 432). 

 As regards the dra-wing^ Mr. Quelch remarked: — '^It is of 

 the exact natural size in every respect. The fibres and t^vigs 

 of Trhich the nest is composed are clearly shown, together with 

 the outer gum-like lining, which serves to bind the edges of the 

 nest together and to attach it to the rocks. The blotches on 

 the tg^ are also very carefully represented.''' 



Mr. ScLATEB. also exhibited a coloured drawing representing 

 the nest of a Guianan Swift [Pajiyptila caytnnensis) of the 

 natural size, drawn by Mrs. George Garnett, of Georgetown, 

 and forwarded to him by Mr. Quelch. He called attention 

 to its resemblance to the nest of P. sancti-hieronymi, Salvin, 

 figured in the P. Z. S. for 1863, p. 191, and read the 

 following notes upon it, extracted from Mr.. Quelch's 

 letter : — 



" This nest is also of the exact natural size and shape. 

 They are built attached on the top to a beam, pendent verti- 

 cally, the aperture being at the bottom. 



" The material used in two nests observed was the fine silky 

 fibres from the dried fruit or seed of one of the silk-cotton- 

 trees {Eriodendroii, sp. inc.), the nest being very soft and 

 warm. The eggs are placed :n a little cup-like shelf on one 

 side, at the very top, where the birds would almost touch the 

 few fibres against the beam. There were two young ones in 

 the nest when taken^ and one escaped, being strong enough 

 to fly.- 



" The cross section of the nest is not round, but oval, and 

 the eggs lie on a shelf in one of the sharp curves. One curious 

 thing in connection with one of the nests was that there were
