206 MR. A. G. BUTLER ON THE GENUS HYPNA. [Apr. 24, 



2. On a New Species of Penelope, lately living in the Society's 

 Gardens. By G. R. Gray, F.R.S., F.L.S., F.Z.S., &c. 



(Plate XXII.) 



Penelope greeyii, sp. nov. (Plate XXII.) 



Entirely shining bronzy aeneous, especially on the wings, rump, 

 and middle tail-feathers ; the feathers of eyebrows, a line from base 

 of lower mandible, and the margin round the naked part of neck 

 grey, with aeneous centres ; nape, lower part of neck, and breast 

 aeneous, with white margins on the sides of the feathers ; upper part 

 of back and wing-coverts slightly margined with grey ; abdomen 

 partly obscure rufous, with black vermiculations and partly plain 

 aeneous ; the feathers of the upper part of abdomen margined, espe- 

 cially on the sides of the feathers, with white ; thighs aeneous, with 

 rufous margins ; under tail-coverts bronzy black ; bill and space 

 round the eyes black ; legs crimson ; throat red, with a few black 

 hair-like feathers. 



Total length 25" 6'", wings 11" 6"'. 



Hab. Santa Martha, New Granada. 



I have taken the opportunity of naming this bird after Mr. Edward 

 Greey, F.Z.S., to whom the Society is indebted for this and other 

 interesting novelties from S ta Martha. 



The specimen described was received by the Society on the 14th 

 of July, 1865, but did not live long in the Gardens. It is now in 

 the British Museum. 



The species is most nearly allied to P. nigricapilla of my Synop- 

 sis of this genus, published in the Society's * Proceedings' for 1860 

 (p. 269). 



3. A Revision of the Genus Hypna, with Descriptions of the 

 New Species. By A. G. Butler, F.Z.S., Assistant, 

 Zoological Department, British Museum. 



(Plate XXIII.) 



A short time since, Mr. Salvia poiated out to me several inconsis- 

 tencies in the various figures of Hypna clytemnestra and also in the 

 specimens of Hypna in his collection, from which it appeared evident 

 that the species of that genus must be more numerous than had 

 hitherto been supposed. 



I subsequently examined the specimens in the National Collection, 

 and easily separated them into four distinct species. One of these 

 has only lately come over from South America ; the three other 

 forms, however, are so distinct that I could see no reason why they 

 should have been placed together. On referring to Mr. Doubleday's 

 ' Genera,' I find the following note : — 



" The only species of this genus is a native of the tropical parts
