sing parts of that country hitherto untrodden by Europeans: it was 
in the high Cordilliera of Chiriqué in Veragua, at an elevation of 
8000 feet, that this bird was found, and of which the individual now 
exhibited was the only one procured. 
CEPHALOPTERUS GLABRICOLLIS. (Aves, Pl. XX.) 
This new species differs in many particulars from its congener, par- 
ticularly in its smaller size, in the lesser development of its umbrella- 
like hood, and in its denuded fore-neck and chest, and in the ab- 
sence of feathers on the base of the tab or appendage at the basal 
part of the neck. M. Warzewickz describes the bare part of the 
neck to be reddish orange, and the bare base of the tab as bright red. 
This fine bird forms part of the collection of T. B. Wilson, Esq., of 
Philadelphia. 
Independently of the novelty just described, M. Warzewickz brought 
me six species of Humming Birds entirely new to science ; these, with 
some other new species of the same group, I propose to characterize 
at a future meeting. 
By Lord Gifford, who has recently returned from a journey in 
Thibet, ornithology has been enriched by the discovery of a new 
species of Syrrhaptes, a form as extraordinary in its way as that of 
any of those above noticed ; the new species is finer both in size and 
colouring than the Syrrhaptes paradoxus ; it was shot on the banks 
of the Stumerrerri Lake, where two examples were seen, but un- 
fortunately only one was procured ; it appears to be an adult male, 
for which I propose the name of 
SyYRRHAPTES TIBETANUS. 
Face hoary ; front and sides of the neck ochreous yellow ; feathers 
of the head and nape brown at the base, and alternately barred at 
the tip with black and white ; upper part of the back, front and 
sides of the breast buffy white, crossed by narrow irregular bars of 
blackish brown ; all the upper surface and wings buff, pencilled all 
over with dark brown, the pencillings being conspicuous on the back, 
and so minute on the wings as to be almost imperceptible ; scapularies 
largely blotched on their inner webs with black; primaries and 
secondaries slaty black, the fourth, fifth, sixth, seventh and eighth 
primaries with an oblique mark of brownish white at the tip ; basal 
half of the two centre tail-feathers buff, pencilled with brown, their 
apical half narrow, filamentous and black ; lateral tail-feathers sandy 
red, crossed by three widely placed irregular bands of black, and 
tipped with buffy white; under surface buffy white, minutely pen- 
cilled on the breast with brown; legs of the same hue, but the 
feathers banded with faint bars of brown ; bill and nails black. 
Total length, 151 inches; bill, $; wing, 10; tail, 71; tarsi, 1. 
Hab, Ladakh in Thibet. 
Remark. Distinguished from the S. paradoxus by its much larger 
size, by the primaries not being extended into the filamentous form 
so remarkable in that species, and by the absence of any black colour- 
ing on the breast.
