1843.] Mr. Blytfis Report for December Meeting, 1842. 1007 



tips of the dorsal fur are also somewhat glistening; and the feet are 

 dark. The other I now designate 



Rh. castaneus, Nobis. Size and structure of the preceding, but the 

 entire colour very much lighter, and the fur considerably less dense: 

 base of the piles pale dusky-ash tipped with vivid light chesnut-bay, 

 which is denser and consequently appears brighter on the cheeks and 

 sides of the head : under-parts merely paler than the upper, the faint 

 ashy hue of the bases of the piles inconspicuous : feet semi-nude and 

 flesh-coloured ; the claws pale : and towards the cleft of the upper lip 

 albescent. Inhabits Arracan. 



Note to p. 928. Among some Darjeeling mammalia lately collected 

 by Capt. Charleton, is a beautiful specimen of the Felis marmorata, 

 Martin, P. Z. S. 1836, p. 107; which, like the F. macrocelis (to 

 which it is allied), was originally described from a Sumatran example. 

 It is the species referred to F. Diardi in the volume on Felince in the 

 * Naturalist's Library.' 



Note to p. 933. Mr. Hodgson now suggests the name Hemirhynchus 

 in lieu of Temnoris. 



P. 938. Capt. Charleton also possesses a specimen of Sitta formosa, 

 Nobis, the wing-primaries of which agree in relative proportion with 

 those of other Nuthatches : and he has several examples of the green 

 Kitta according precisely with that described, which, as Mr. Hodgson 

 informs me, are merely in the ordinary plumage newly put forth, the 

 colour changing to blue after a certain amount of exposure. 



The same collection has also yielded a fourth species of my genus 

 Cyornis, as alluded to in a note to p. 941 ; viz. 



C. unicolor, Nobis. Differs from the three others, in having no 

 ferruginous on the under-parts ; whilst the upper are of a lighter blue 

 than in C. rubeculoides and C. banyumas, and of a much brighter and 

 less greyish blue than those of C. Tickellice : lower-parts paler and 

 tinged with verdigris, being still lighter on the belly. The only spe- 

 cimen examined was killed while moulting, and retains many of its 

 mottled nestling feathers, especially upon the head and throat, also 

 the wing-coverts, and an intermixture of them on the bright blue 

 dorsal plumage : these nestling feathers are pale fulvous-brown with 

 narrow black margins on the clothing plumage, the wing-coverts are 

 dusky with pale fulvescent tips, and the large alars are tinged with
