ones being slightly banded below with greyish-white ; length 14 

 inches. Legs feathered to the toes. Toes furnished with three scu- 

 tellae, which are largest on the back one; feet yellow ; claws bluish- 

 grey. Hab. South America. The Professor applied the specific 

 term Nigra to this bird, from black being the predominant colour 

 of its plumage, and remarked with regard to the generic name 

 Aquila, that it belongs to that genus, of which the type is Aquila 

 fulva, from the cutting edge of the upper mandible being fur- 

 nished with a protuberance ; the wings considerably shorter than 

 the tail ; tarsi feathered to the toes ; and lastly, the first phalanx 

 of all the metatarsal bones being provided with three scutella?. 



Lophophorus Nigelli, male. — This bird was remarked by the 

 Professor to differ from the female already described, in being 

 larger, in having two reddish-brown bands, the one extending 

 from the external angle of the eye, the other from the lower part 

 of the auricular coverts, down to the under part of the neck, 

 where they unite and form a broad diffused ring round it ; in 

 the breast being yellowish-white, and some of the feathers with 

 a band of black in their centre ; and lastly, in having the feathers 

 of the hypochondriac region more strongly marked, and tipped 

 with a much deeper brown. Like the female, it wants the spur. 

 From the form of the bill, and the absence of the spur in the 

 male, which is so prominent in the other species which have been 

 included in the genus Lophophorus, this has now formed a new 

 genus. The distribution of this species, the Professor remarked, 

 was very wide, from its occurring from Persia, where the female 

 was first discovered, onwards to the Himmalayan Mountains. 



A paper was read on the Manners and Customs of the Bosh- 

 men of the Sternberg Orange River, communicated by Mr 

 Leslie, and a notice on the Deluges of Deucalion, Ogyges, and 

 Noah.
