The Eastern Swallow.

Hirundo gutturalis, Scop. Del. Flor. et Faun. Insubr. ii, p. 96 (1786); Hume & Dav. S. F. vi, p. 41; Hume, Cat. no. 82 bis ; Sharpe, Cat. B. M. x, p. 134. Hirundo panayana, Om. Syst. Nat. i, p. 1018 (1788) ; Horsf. & M. Cat. i, p. 91. Hirundo andamanensis, Tytler, Beavan, Ibis, 1867, p. 316; Ball, S. F. i, p. 55 ; Hume, Cat. no. 82 quat.

Coloration. Resembles H. rustica, but the chestnut of the throat, encroaches on the black pectoral band so as to nearly sever it down the middle of the breast; the lower plumage below the pectoral band is pure white.

Length about 6.5 ; tail 3.6; wing 4.6; tarsus .4 ; bill from gape .6; bifurcation of tail 1.7.

Typical examples of this Swallow from Japan and North-eastern Asia are very distinct from H. rustica, the lower plumage being pure white and the pectoral band severed in two by the encroach¬ment of the chestnut of the throat. Many examples procured in Burma are sufficiently typical to be easily recognizable, but the majority of Swallows from the eastern portion of the Empire are quite intermediate between the two species.

Distribution. Common in winter over the whole of the Empire east of the Bay of Bengal and extending to Assam and Bengal. The western limits of this species cannot be determined with any accuracy, as many birds from the continent of India are quite intermediate between H. rustica and H. gutturalis, and I have seen no bird which could unhesitatingly be assigned to H. gutturalis from any point west of Calcutta. This species ranges from North-eastern Asia to the Malay islands and Singapore.
