Adult male. Mead, neck, mantle, scajjulars, upper tail-coverts, and entire under 
parts yellow-green, brighter on tbe bead; lower back and rump bright turquoise- 
blue; wings parrot-green, the lesser coverts and some of the inner median coverts 
margined broadly with blue, darker than that of tbe rump, tbe other wbig-coverts 
and tertiaries margined with yelbnv-green ; tail above parrot-green, yellowish at tbe 
tip; tail below golden olivaceous, shafts below white, above blackish; quills below 
shining brownish mouse-grey (Tjamba, S. Celebes, April 1878 — C 10423). “Eds 
light yellow; cere browni.sh; bill coral-red, point lighter; feet grey-brown (Platen). 
Another old male (Mus. Nehrkorn) labelled by Dr. Platen, Eurukan, has: “bill 
sealing-wax-red (lackrot); cere grey-black; feet yellow-brown.” 
Adult female. Like the male, but duller and greener; mantle and scapulars parrot-green 
like the wings ; little or no trace of blue tips to the lesser wing-coverts (Limbotto — 
C 1904). “L-is light yellow; bill horn-white; cere grey-black; feet yellow-brown” 
(Q Eurukan, Platen in Mus. Nehrkorn). 
The female may be at once distinguished from the old male by its green mantle 
and scapulars, and white bill, though in some females (perhaps very old ones) this 
may assume a reddish colour. 
Young male. Head duller darker green than in the female, otherwise like it; lower back 
and rump duller blue than in the old male. “Iris light yellow; cere brownish; bill 
light red; feet brown-grey” (Tjamba, 25‘’‘ April, 1878 — Platen C 11206). 
Measurements. Wing (34 specimens) 196—212 mm; tail 121, 137 (largest- and shortest- 
winged specimens); culmen from cere 30—34.^; tarsus 19—21. Females as a rule 
are a trifle smaller than old males, and the bill is smaller.
