As regards the drawing, Mr. Quelch remarked: — "It is o£ 

 the exact natural size in every respect. The fibres and twigs 

 of which 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 e^g are also very carefully represented." 



Mr. ScLATER also exhibited a coloured drawing representing 

 y the nest of a Guianan Swift {Panyptila cayennensis) 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 follow- 

 ing notes upon it, extracted from Mr. Quelch^s letter : — 



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

 The nests are built attached on the top to a beam, pendent 

 vertically, 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 {Eriodendron, sp. inc.), the nest being very soft and 

 warm. The eggs are placed in 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 cui'ious 

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

 no silk-cotton-trees from which the silky hairs or fibres could 

 be obtained for a distance of some miles from its position. 

 The nest was taken from under a house in Leguan (an 

 island in the estuary of the Essequibo) by Mr. H. Straker, 

 sub-immigration agent." 



Mr. W. Eagle Clarke sent an account of the occurrence 



-^ of the Frigate- Petrel {Pelagodroma marina) on the west side 



of Scotland. The bird, a female, was captured alive on
