 dated Tripoli, January 4th, announcing that he has in his possession 

 five Birds of Carthage, Pterocles guttatus ?, Temm., alive and quite

 " Silver Pits," eighty miles eastward of Scarborough, Avas presented 

 by Mr. Ingarfield. 



A communication was read from James Stark, M.D., F.R.S.E., 

 in \vhich he advocates the hypothesis that the Tetrao medius is neither 

 a hybrid nor a distinct species, but merely an immature malė of the 

 Tetrao Urogallus or Capercailzie, founding his opinion on the ap- 

 pearance of the Tetrao medms immediately after the re-introduction 

 of the Capercailzie into Scotland by the Earl of Breadalbane, and on 

 the fact, that no two species of a genus, however similar they may 

 be in appearance, pair voluntarily while in a statė of nature. 



Mr. Fraser laid before the Meeting a collection of Birds' Skins 

 which have been presented to the Society by Lieut.-Colonel 0\ven, 

 K. C. A., of Oporto, containing the following siDecies: viz. Buteo vul- 

 garis, Flem.; Slurnus vulga7-is, hinn. ; Pica caudata,Flem.; Garru- 

 lus glandarius, Flem. ; Picus major ? ; CEdicnemus crepitans, Selby ; 

 Fulica ater, Penn. ; Spatula {Anas clypeata, Linn.) ; Mareca {Anas 

 Penelope, Linn.), and Larus argentatus, Mont. 



The Secretary called the attention of the Meeting to a specimen 

 of a new species of Lagomys, discovered by Bryan H. Hodgson, Esq., 

 Corr. Memb., in the Nepaul district, which he describes as Lagomys 

 Nepalensis. The present species adds a seventh to this most in- 

 teresting group.
