Glareola ovicntalis (Oriental Pratincole). — Breeds in southern 

 Dauria. 



Apus {Micro pus) pacificus (White-rumped Swift). — Breeds from 

 steppes of Akmolinsk Government, in south-western Siberia, 

 through Siberia, and as far north as at least 58^'' X. on Yenisei 

 and 60° N. on Lena. 



Hiriindo gutturalis (Eastern Swallow). — South-eastern Siberia. 

 (All my specimens from Kolyma, Yana, middle Lena, and south- 

 eastern part of Yeniseisk Government — basins of Chuna and Mura, 

 left tributaries of Angara or upper Tunguska — belong to H. 

 tythleri ; and specimens from Yeniseisk Government, west of qif 

 E. from Greenwich, to H. rustica typica). 



T may add that Acanthyllis {Chcetura) caudacuta (Spine-tailed 

 Swift) breeds from upper parts of Yenisei as far north as Yeniseisk, 

 and in Amur Land to the northern parts of Amur basin.

Puffinus intermedius, n. sp.— Solitary Petrel. 



Adult Male. — General colour above blackish-brown, feathers of 

 the back narrowly margined with lighter ; crown of the head 

 black ; throat, sides of the neck, and entire under surface greyish- 

 brown, the shafts of the breast feathers black ; bases of all the 

 body feathers grey, darker towards the tip ; wing coverts and 

 secondaries blackish-brown, margined with lighter ; primaries 

 darker ; under wing coverts ashy-grey, with black shafts ; rump 

 and upper tail coverts black, broadly margined with dark grey ; 

 outer tail feathers sooty-black, the central feather distinctly 

 longer than the others. 



Bill lead colour : tarsi lead colour in front, bluish behind : toes 

 black ; interdigital membrane bluish-black above, darker beneath ; 

 iris black. 



Total length. 17 inches : wing, 10.5 : tail, 3.5 : bill, 1.25 : tarsus, 

 2 ; middle toe and claw, 2.5. 



Compared with Puffinus hrevicaudus (Gould), this bird is larger 

 (4 inches longer), more robust, has a stouter bill, and is generally 

 lighter in colour. It differs from P. griseus (Gmelin) in its 

 slightly smaller size, much smaller and slighter bill, darker colour, 

 and the absence of the white under wing coverts. 



The type specimen was taken by me, in company with Mr. 

 Thos. P. Austin, at Cabbage Tree Island, at the entrance to Port 

 Stephens, New South Wales, on the 4th December, iqio {vide 

 Emu, vol. X., p. 257). The bird was discovered in a burrow 

 beneath a boulder in the scrub about half-way towards the top of 

 the island. Quite close to this burrow a male Wedge-tailed Petrel 

 was also found in a similar retreat. Both birds appeared to be 

 merely in hiding, and there was no apparent intention of using 

 the hiding-]:)lace as a nest.
