Mr. Tegetmeier exhibited a collection of skins of new varieties of 

 domestic Fowls, the property of Mr. C. Darwin. 



Those from the Madras Presidency were chiefly of the Malay type, 

 more or less resembling the gigantic Kulm Fowls that were imported 

 some years since by Colonel Sykes, and which were formerly in the 

 possession of the Society. The Fowls from Singapore were remark- 

 able for the recurved character of the plumage. The interior of 

 Persia furnished a very beautiful steel-black variety, perfectly distinct 

 from any known in this country, and which was stated to be the 

 Common Fowl of the district. Good specimens of the black-skinned, 

 white silky-plumaged Fowl with black periosteum were forwarded 

 both from Singapore and Madras. Mr. Tegetmeier called attention 

 to the fact, that all the specimens shown differed in a much greater 

 degree, than our common English Game Fowls, from the Gullus 

 Bankiva, so frequently asserted to be the origin of our domesticated 

 species of the genus Gallus.

The only individual of this species which I have yet seen is that 

 in the British Museum. It is easily recognizable among its conge- 

 ners by its thrice-banded wings. I am now acquainted with seven 

 birds which I consider to be probable members of this genus, viz. — 

 (1.) cayanensis, Bodd. ex. PI. Enl. 821 (co/ma, Gm. et Bodd., 

 tetema, Licht. , fuscicapilla, Vieill., ruficeps, Spix), ex Guiana et 

 Brasilia. (2.) analis (Lafr. et d'Orb.), Voy. d. l'Am. Me'r. Ois.
