Thomas Bell, Esq., in the Chair. 



At the request 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 been so imperfectly understood 

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

 species. 



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

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

 sion : they were the Phasianus Soemmeringii, Temm., and the P has. 

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

 the subdivisions which appear to him to be required among the Pha- 

 sianidcs 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 Collections obtained by Mr. Cuming and 

 Mr. Miller. (txihvi?,\, Oxyrhynchi.)" The paper 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.
