1843.] Mr. Blytlis Report for December Meeting, 1842. 953 



The only additional species which I at present know of, are four 

 described from Western Africa by Mr. Swainson, and one discovered 

 in Southern Africa by Dr. A. Smith :* there are doubtless, however, 

 several more yet to be discovered in this country. Of those here enu- 

 merated, Nos. 3, 4, 6, 8, 12, 13, 14, 15, 17, 25, and 29, are desiderata 

 in the Society's Museum ; which contains only bad specimens of some 

 of the others, as 22 and 23. The Cincl. Nipalense, Hodgson, as 

 before noticed, has since been referred by that naturalist to his genus 

 Alcopus (v. Actinodura, Gould); and now ranks as the type of his 

 genus Ixops. 



Leiocincla, Nobis, n. g. Intermediate to Garrulax, Ixops, and 

 Leiothrix, the very elegant bird upon which I found this generic 

 designation has the bill shorter than the head, moderately compressed, 

 somewhat wide at base, the outline of both mandibles accurved, and 

 the tip of the upper bent over that of the lower mandible, rendering 

 the slight arcuation of the former more apparent: nostrils basal, their 

 aperture a narrow slit at the inferior margin of the nasal membrane : 

 gape furnish with a few long but feeble bristles. Tarse of mean length, 

 or rather short than otherwise: the toes formed for perching, and 

 claws of moderate size. Wings having the first primary half the 

 length of the third, and the fifth, sixth, and seventh, equal and longest. 

 Tail long and graduated. The plumage very copious, dense and of 

 silky texture, especially on the crown and occiput, where the feathers 

 are much lengthened. 



L. plumosa, Nobis. Entire length about nine inches, of which 

 the tail measures five, its outermost feathers two inches less ; wings 

 three inches and three-eighths ; bill to forehead, through the reflected 

 frontal plumes, three-quarters of an inch, and seven-eighths of an 

 inch to gape ; tarse an inch. General colour different shades of soft 

 brown, passing into rufous and delicate cinerous-lake ; the latter pre- 

 vails on the lengthened feathers of the crown and nape, and upon the 



The Turdus canorus, Lin., is referred to Ianthocincla by Mr. Strickland, in a list 

 of Chinese birds published in the ' Annals and Magazine of Natural History' for 

 September 1843. This is the Baniahbou de Bengaleoi Buffon, who appears, however, 

 to mix up two different species under this name, from Bengal and China respectively. 

 I do not recognise the Bengal bird described by him, but may remark that the native 

 name he cites is commonly applied to the Black-headed Oriole. 



* Crat. Swainsonii, A. Smith, may be one, the figure of which I have not seen; 

 but Cr. Jardinii of the same naturalist would seem to be a Malacocircus.
