bilobed valve which is there represented, though not described in

Mr. Vigors exhibited a collection of African Birds which had 

 been presented to the Society by Henry Ellis, Esq., of Portland 

 Place. They consisted of about one hundred and thirty species, 

 many ot them of extreme rarity and value, and a great portion un- 

 known to the cabinets of England. They came immediately from 

 Algoa Bay ; but were supposed to have been collected far in the 

 interior of the country. Mr. Vigors expressed his intention of lay- 

 ing before the Committee at an early Meeting, a descriptive cata- 

 logue of the whole collection, as well as whatever particulars he could 

 collect respecting the locality from which it was brought. He named 

 and characterized in the mean time the following apparent novelties 

 from the Insessorial Birds.

* A group including the shining Cuckoos of Africa, India, and New Hol- 

 land, indicated in the Transactions of the Linnean Society, vol. xv. p 300. 

 Mr. Vigors expressed his belief of having lately seen a name attached to 

 this group by some modern author ; but he could not call to his recollection 

 the work in which it occurred.
