Mr. Goiild also exliibited specimens of the malė and female of 

 the Trogon pavoninia, Spix: the latter, he stated, bas hitherto 

 escaped the observation of ornithoiogists. It bas recently been 

 acąuired for the Society's collection. 



The female ratber exceeds the malė in all her proportions. Her 

 bill is black instead of yeliow: her crest is shoiter, and bas bronzy 

 reflections. The \vhole of the under surface is of a brovvnish grey, 

 with the exception of the under tail coverts, vvhich are scarlet. 

 The outer tail feathers, which in the malė are white with black 

 shafts, are in the female barred, except at the base, where they are 

 duU black. The colours of the upper surface are similar in both 

 sexes; but the plumes which spring frora the rump, and which in 

 the raale attain so remarkable a length, scarcely extend in the fe- 

 male beyond the tip of the tail. 



A " Description of Perdix Lervoa" by B. H. Hodgson, Esq., Corr. 

 Memb. Z. S., was read. It was accompanied by a coloured draw- 

 ing of thebird, vvhich inhabits the northern region of Nepfil, and 

 forms, by its half-plumed tarsi, a sort of link between tlie Partridges 

 and the Grouse. Its habits assimilate with those of the latter genus. 

 It is found close to the permanenl snovvs, among rocks and low 

 brushvvood, and sustains itself upon aromatic buds, leaves, and small 

 insects. It is characterized as follows : 



Perdix Lervva. Perd, nigra, albo casianeoque transversitn line- 

 ata ; pectore brunneo ; tarsis ultra calcar plumosis ; remige 2dd 

 longiore. 



The great comparative expanse of the wing ; the diminution of 

 its rounded form by the second quill feather being the longest ; the 

 increased length and strength of the tail ; and the extent of the 

 feathering of the tarsi, are very remarkable characters, which give 

 to this species a peculiar interest. Its dimensions, as compared with 

 Severai allied birds, are given by Mr. Hodgson in the follovving tabie:
