(683) Niltava grandis decipiens.
The Malay Large Niltava.
Niltava grandis decipiens Hartert, Nov. Zool., ix, p. 551 (1902) (Sumatra).
Vernacular names. None recorded.
Description.— Adult male. Almost indistinguishable from N g. grandis but is smaller with the blue of the head and rump rather brighter.
Colours of soft parts as in the last bird.
Measurements. Wing 94 to 103 mm., generally under 98 mm.
Female similar to that of N. g. grandis, but with the crown and nape strongly washed with blue, though never bright blue as in N. g. decorata of Robinson and Kloss (Annam).
Young and Nestling. Similar to those of the Indian Large Niltava.
Distribution. Sumatra and Malay Peninsula.
With some hesitation I place two females from Muleyit with this race. In colour, as Hartert points out, they agree with the Sumatran birds but they have wings of 99 and 101 mm. respectively, rather large for this race, though one male from Sumatra has a wing of no less than 103 mm.
Habits and Nidification. Nothing recorded.
