either a distinct species or, from the peculiarity of the bill and feet, 

 a bird of the first year. The bill, feet, and legs were of a flesh- 

 colour ; the plumage of the head, neck, wings, centre of the back, 

 tail, and thighs glossy-black ; remainder of the plumage white. 

 These birds are readily domesticated, and run about the poultry- 

 yard in the most amicable manner possible. The colour of the beak, 

 feet, and legs were of the same colour when hatched ; and the bird, 

 dating from the time it was brought forth, would be one year and 

 eight months old." 



Mr. Gould exhibited a drawing of a Pheasant, said to come from 

 the Mountains of Siam, which he considered identical with that 

 lately described by Mr. Blyth under the name of Biardig alius 

 fasciolatus, Journ. As. Soc. Beng. xxvii. p. 115.

The following papers were read:— 



1. Descriptions of New Species of the American family 

 TyrannidtE. By Philip Ltjtley Sclater. 



1. Attila citriniventris. 



Rufescens, capite obscuriore et cinereo tincto, dorso imo dilutiore, 

 uropygio citrino-flavo : alis nigricantibus, extus rufescente lim- 

 batis ; gula cinerascente, pectore rufo, ventre cum crisso 

 citrino-flavo , hypochondriis et tectricibus subalaribus rvfis : 

 cauda clare rufa unicolore, basin versus dilutiore : rostro ni- 

 gricante, p edi bus plumb eis. 



Long, tota 6' 75, alee 32, caudse 2'6, rostri a rictu I'O. 



Hab. In valle Amazonum superiore ad ripas fl. Ucayali (Haux- 

 well). 



This species of Attila comes nearest to Attila spadiceus of Cayenne 

 and Northern Brazil, and is of about the same size, but may be di- 

 stinguished by its darker and more cinereous head and yellow belly, 

 as well as minor differences. An example in my own collection was 

 received from MM* Verreaux of Paris. One belonging to Mr. Gould 

 was procured by Hauxwell on the Ucayali. 



As to the position of this genus of birds and the synonymy of the 

 species, I agree with the views of M. de Lafresnaye, as given in his 

 article in the 'Revue Zoologique' (1848, p. 39). '
