 1. Descriptions of new Birds. By J. Gould, F.R.S. &c. &c. 



It is no less interesting than true, that during the past two years we 

 have had accessions in ornithology of no ordinary value ; comprising 

 as they do additional species of several anomalous forms, of each of 

 which only one was previously known ; for instance, we have a second 

 species of the genera Apterxjx, Menura, and Ptiloris. On the present 

 occasion I have the good fortune to offer to the notice of this Meet- 

 ing new species of two forms, equal in interest to those above referred 

 to, viz. that of Cephalopterus, a form known to all as being American, 

 and of which the type is the remarkable species Cephalopterus orna- 

 tus, commonly called the Umbrella Bird. The discovery of a second 

 species of this form is due to the researches of M. Warzewickz, a 

 gentleman who has just returned from Central America, after traver- 

 sing parts of that country hitherto untrodden by Europeans : it was 

 in the high Cordilliera of Chirique in Yeragua, 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. 



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 Sijrrhaptes, 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 banka 

 of the Stumerrerri Lake, where two examples were seen, but un- 

 fortimately only one was procured ; it appears to be an adult male, 

 for which I propose the name of 



Syrrhaptes 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
