had been called Phylloscopus sibilatrix flavescens by Erlanger 

 from Tunisian specimens. Although skins of this form 

 could sometimes hardly be distinguished from typical 

 European P. sibilatrix, Mr. Hartert was now fully convinced 

 that P. flavescens must be separated, as its song was very 

 different from that of true P. sibilatrix. 



Mr. Hartert also exhibited a skin of a fine new species of 

 Collocalia discovered by Mr. A. L. Butler in the interior 

 of Selangore. The name proposed for the species was 



Collocalia gigas, Hartert & Butler, n. sp. 



$ . Differs from C. fuciphaga, with which it agrees in 

 colour, and all other Collocalia in its enormous size. Wing 

 157, tail 64, tarsus 15 mm. (the latter bare, except in front 

 on its upper portion for 4 mm.) ; fork of tail about 4 mm. 



The Hon. Walter Rothschild exhibited a small King- 

 fisher from Yamdena, in the Timor-Laut Islands, which was a 

 near ally of Alcyone azurea pulchra from North Queensland, 

 but differed in its smaller size and in the distinct brownish 

 tip to the bill. In this latter peculiarity it resembled Alcyone 

 azurea affinis from the Northern Moluccas, which had a red 

 tip to the bill, but was much larger and had a much more 

 powerful bill. The type of 



Alcyone azurea yamdena, subsp. nov., 

 as Mr. Rothschild proposed to call the new form, had 

 a wing of only 71 mm., the tail 30, bill (along the culmen) 

 48 mm. 



This specimen had been obtained by Mr. H. Kuhn. 



Mr. Harting exhibited a specimen of a Falcon killed in 

 Essex, and invited the opinion of the members present as to 

 whether the bird was a Peregrine or a Norway Jer- Falcon. 



A discussion took place, in which Mr. J. G. Millais, 

 Mr. G. E. Lodge, Mr. Neale, Mr. Munro, and Mr. Dresser 

 favoured the idea of the bird being a dark variety of a 

 female Falco peregrinus, while the Hon. Walter Rothschild,
