Hab. Very abundant during the breeding season on the Houtman's 

 Abrolhos, off the western coast of Australia. 



Remark. — This species, although very nearly allied to, is distinct 

 from the Anous tenuirostris (^Sterna tetmirostris, Temm.) of 'Western 

 Africa, from •vvhich it may at once be distinguished by the black marks 

 before and behind the eye, of which no trace is represented in M. 

 Temminck's figure in the ' Planches Coloriėes ' ; neither is this con- 

 spicuous mark alluded to in his description. It is just possible that 

 this may be the species described by \l. de la Fresnaye in Guerin's 

 Magazine, under the generic name of Procellosterna.

A single specimen forms part of the collection of the Zoological 

 Society, to whom it was presented by F. Debell Bennett, Esq., \vho 

 procured it at Christmas Island, in the South Seas. It may be di- 

 stinguished from all the other species by its small size and delicately- 

 formed bill. 



Mr. Gould then exhibited two new birds from New South Wales : 



PoDARGUS PLUMIFERUS. Pod. plumis Tiūres tegentibus, quee sunt in 



cristcE formam erecta, nigro-fusco et albo alternatim fasciatis ;
