Thomas Bell, Esq., in the Chair. 



At the reąuest of the Chairman, Mr. Gould exhibited a specimen 

 of the true Lanner Hawk, Falco Lanarius, Linn., and entered into 

 some details with respect to its distinguishing peculiarities. Its real 

 characters, he stated, have hitherto beea so imperfectly understood 

 as to have led to very general doubts as to its existence as a distinct 

 species. 



Mr. Gould also exhiblted specimens of two species of Pheasant, 

 both of very great rarity, wliich had recently come into his posses- 

 sion : they were the Phasianus Scemmeringii, Temm., and the Phas. 

 versicolor, Ej. He accompanied the exhibition by some remarks on 

 the subdi^isions which appear to him to be reąuired among the Pha- 

 sianidee generally ; and more especially on the position, among that 

 extensive group, of the species exhibited. 



Mr. Bell read " Some Account of the Crustacea of the Coasts of 

 South America, with Descriptions of New Genera and Species; 

 founded principally on the CoŪections obtained by Mr. Cuming and 

 Mr. Miller. (Tribus I, Oxyrhynchi.)" Thepaper contains characters 

 and descriptions of the following genera and species of Crustacea ; 

 and was accompanied by the exhibition of the specimens described 

 in it, and of drawings in illustration of it.
