posed the name Perdix Bonhami, were procured at Tehran, in Persia, 
by Edward W. Bonham, Esq., H.M. agent at Tabreez, Persia, and 
presented to the Society by that gentleman, together with a living 
specimen of the Tetraogallus Nigelli from the same locality, which 
having died had been stuffed, and was exhibited at the Meeting. 
The new Partridge was thus characterized :— 
Prerpix Bonnami. Perd. arenaceo-flava, plumis nigro adspersis 
presertim apud latera, collum et pectus, hoc notd circulari ornato ; 
strigis superciliaribus subocularibus, et frontalibus nigris ; plumis 
auricularibus albis, laterum plumis nigro-marginatis ; rectricibus 
caud@ quatuor externis crissoque rufis ; rostro corneo. 
Foemina distinctiiis adspersa, quamvis notis nigris auribusque albis, 
maris signis, caret. 
This species is nearly allied to Perdix Heyi, Temm. Pl. Col., but 
is readily distinguished from that bird by the black stripes about the 
head of the male. The female differs in having a more mottled ap- 
pearance. 
Mr. Yarrell exhibited a specimen of the Puffinus obscurus from 
the Dardanelles, and called attention to some peculiarities in its 
habits, as pointed out in the ‘ Familiar History of Birds,’ &c. by the 
Rev. Edward Stanley (now Bishop of Norwich), to whom the speci- 
men belonged. Considerable interest is attached to the bird exhibited, 
since, though often alluded to by travellers who have visited the 
Dardanelles (but under native names only),naturalists were not aware 
to what species the accounts referred; and moreover certain preju- 
dices of the inhabitants render it extremely difficult to procure this 
species of Petrel from the locality mentioned.
