racters proposed by that gentleman. It is placed by him among the Scan-

NYCTYORNIS, Swain. 

 " Bill subfalcated, compressed, margins of the upper mandible folding over those of the lower, 

 rictus excessively wide. Wings rounded, moderate ; plumose, lax and long. Tarsi 

 much shorter than the hallux. Toes and claws as in Merops and Prionites.'" 



PHCENICURA TETHYS et ATRATA, Plate 86. 



The genus Phosnicura has been formed by Mr Swainson in the 2d vo- 

 lume of the Northern Zoology now in the press, to contain those birds 

 generally known under the denomination of Redstarts, and we have adopted 

 it for the species described in our last Number. 



We cannot close our second Volume without returning to those gentle- 

 men with whom we have the honour to co-operate, our acknowledgments 

 for the ready assistance we have at all times received from them. Indivi- 

 dually to Mr. Children, for his valuable account of Phytotoma ; — to Mi- 

 Vigors, for various information regarding those birds belonging to the 

 Zoological Society of London ; — to Dr. Horsfield, General Hardwicke 

 and Mr Bicheno, for their aid whenever we had occasion to apply to those 

 sources over which they exercised any controul ; — and to Professor Jame- 

 son, for those specimens which we have received from the Royal Edin- 

 burgh Museum. To other gentlemen our thanks are also due ; — to Mr. 

 James Wilson and Dr. Gillies for interesting accounts of Lophophorus 

 Nigelli and Psittaca Calita; — and particularly to Mr Swain son, for the in- 

 formation he has so often and so liberally communicated, and for the many 

 interesting species he has at various times sent for our examination and 

 comparison. We are happy to add, that we shall in future be enabled to 

 rank that gentleman among our regular co-operators, and we estimate his 

 value by what he has already done for us.
