 innermost greater coverts ashy on their inner web, tinged with rufous ; bastard-wing, primary- 

 coverts, and quills blackish, externally glossed with steel-green ; tail-feathers blackish, glossed with 

 steel-green, all but the centre feathers with a spot of pale rufous on the inner web, becoming 

 laro-er towards the outermost, where it is in the form of a large oblique mark ; frontal band deep 

 chestnut; lores black ; ear-coverts and sides of neck glossy purplish blue; cheeks and throat 

 deep chestnut, with a half-collar of glossy purplish blue coming down on the sides of the fore 

 neck, but not forming a band across ; remainder of under surface of body bright chestnut, not so 

 deep as the throat ; the under tail-coverts equally bright chestnut like the breast, and having 

 slightly indicated spots of purplish blue at the ends of the feathers ; axillaries and under wing- 

 coverts exactly like the breast, the coverts near the edge of the wing slightly mottled with ashy 

 bases to the feathers ; quills dusky below. Total length 7-8 inches, culmenO-4-, wing 5-9, tail 5-7, 

 tarsus 0"4. 



Hab. North-eastern Asia from Irkutsk to Kamtschatka, visiting Pekin and probably breeding there. 

 Wintering in the lowlands of Dacca, the Burmese provinces, and Tenasserim, and even extending 

 to South America. 



Tytlee's Chimney-Swallow bears the same relation to Hirundo giitturalis that 

 H. savignii does to H. riistica. It is an intensely rufous bird without a perfect collar. 

 We know that the species nests in Kamtschatka, and it has been said to breed in the hills 

 of Assam and Manipur ; but this statement is, in our opinion, erroneous. 



"We identify with //. tytleri specimens in the British Museum from the following 

 localities : — Kamtschatka, Irkutsk, Sadhyia, Khasia Hills, Cachar, Dacca, Pegu, and 

 Tavoy, as well as three American specimens from Brazil, Para, and Duenas in Guatemala. 



That all the specimens from the Indo-Burmese countries are typical H. tytleri, we 

 would not, however, assert, for some of them incline to the possession of a throat-band, 

 and both from Dacca and Tavoy we have seen specimens which we regard as intermediate 

 between H. rustica and H. tytleri, while an individual from the Gurgaon district near 

 Delhi appears to fall within the same category. 



The northern range of Tytler's Swallow has been well discussed by Dr. Stejneger in 

 his celebrated work on the ornithology of Kamtschatka and the Commander Islands, 

 and he agrees that the rufous-breasted Swallow of these localities cannot be specifically 

 distinguished from typical //. tytleri. In Kamtschatka, according to Dr. Stejneger, the 

 " Brown-bellied Swallow," as he calls it, breeds abundantly in and about Petropaulowski, 

 where he met with it during the months of June and July 18S2. He adds : — " When, in 

 1883, I left the town on one of the latter days of May they had not yet arrived from the 

 south, and at my arrival there in the middle of September the last one had already 

 disappeared, so that their Avhole sojourn lasts less than three months. Mr. Joseph 

 Lugebil informed me that the Swallows arrived on June 3, and disappeared on 

 August 19. During the migration in spring a few stragglers sometimes pay a flying visit 

 to Bering Island." Thus two were reported to Dr. Stejneger from the North Eookery 

 on June 19, 1893, and another was observed at Ladiginsk three days later. A single 

 egg left in the nest was procured in the fall ; it was white, heavily spotted with lilac
