(820) Orthotomus sepium cineraceus.
The Ashy Tailor-Bird.
Orthotomus cineraceus Blyth, J. A. S. B., xiv, p. 589 (1845) (Malacca).
Vernacular names. Nok-a-chip (Siam).
Description. Forehead, anterior crown, lores, sides of head, chin, sides of throat and supercilium bright cinnamon-rufous; posterior crown and upper plumage ashy-grey; tail brown, tipped pale fulvous-white and sub-tipped dark brown ; wing-quills brown edged with rufescent; below ashy-grey, deepest on throat and upper breast, albescent on the centre of the belly ; under tail-coverts pale buff.
This race differs from typical O. s. septum in having the abdomen whitish instead of tinged with greenish and in having no green on the upper parts. From borneonensis of Salvadori it is distinguished by its rather lighter plumage and less deep rufous on the head.
Colours of soft parts. Iris Naples-yellow ; bill light horny-brown above, pale yellowish below; feet and legs tan-brown, or "pale warm brown" (Everitt).
Measurements. Total length about 100 mm.; wing 46 to 52 mm.; tail 34 to 46 mm.; tarsus about 19 ram.; culmen 14 to 16 mm.
Female. Much paler below and with the rufous head-markings very pale and weak.
Young. Like the female but more olive above and dull yellowish white below.
Distribution. South Tenasserim and Siam to Singapore and Sumatra. There is also one specimen from Cochin China in the British Museum collection.
Nidification and Habits. I can find nothing recorded.
