of this species to the north and west are unknown, and it must
remain doubtful for the present whether this Sun-bird extends to
Arrakan or not.
885. JEthopyga nicobarica. The Nicdbar Yellows-backed Sun-bircL
^Ethopyga nicobarica, Hume, S. F. i, p. 412 (1873) ; Shelley, Mm. Nect. pp. xx, 61, pi. 20 ; Hume, Cat. no. 225 bis ; Gadow, Cat. B. M. ix. p. 22.
Coloration. Male. Differs from JE. seherice in having the metallic portion of the crown of very small extent and suffused with violet ; the nape crimson ; the moustachial stripe lined with black interiorly ; the exposed parts of the tail violet, not green.
Female. Differs from ^E. seherice in wanting the yellow on the flanks ; in having the tail 1'3 inches in length, the lateral feathers being only '2 shorter than the middle pair ; and in having a much broader and a pale-coloured bill.
The male agrees with that of &. cara in having short middle tail-feathers, but differs from it in having a smaller cap and the moustachial stripe lined with black.
Both Hume and Shelley are in error, I think, in asserting that the female of this species has the throat red ; three specimens in the Hume Collection, sexed as females ib is true, but having the throat red, are in my opinion young males, and the females when obtained will probably prove to be green birds without a trace of red, as is the case with all the other species of this genus.
This species differs from ^E. siparaja, which inhabits the Malay peninsula, Sumatra, and Borneo, in having a much longer bill. In JE 1 . siparaja the bill measured at front is '6.
Male : legs, feet, and upper mandible dark brown ; lower mandible pale brown ; iris brown. Female : upper mandible horny brown ; lower mandible, legs, and feet yellow ; iris brown (Hume).
Male: length about 5; tail 2 wing 2*1 ; tarsus *5; bill at front -75.
Distribution. The Nicobar Islands.
