Osmatreron, chloroptera andamanensis Butler, ib. 

 Vernacular Names. None known. 



Description. — Adult male. Differs from the male of phayrei in having 

 the lower wing-coverts green, of a darker, less yellow tinge than the neck, 

 and the green of the upper-parts is more yellow except on the central rectrices. 

 The maroon on the back is darker than it is in phayrei, and as dark as it is 

 in affinis. There is no orange on the breast and the lower tail-coverts are 

 dark, rather dull green, with broad yellowish- white borders. The grey of 

 the head is lighter and unmixed with green on the fore-head, fading into the 

 green of the lower half of the lores and also merging into the green of the 

 neck, from which it is never sharply defined. 



Legs and feet pale carnation-pink or purplish-pink, claws homy or 

 plumbeous tiaged with pink ; bill a whitish-blue or leaden-blue tinged with 

 green near the base, and with plumbeous cere. Iris, first ring pale blue, 

 second ring darker blue, and third ring fleshy-buff. Orbital skin plumbeous, 

 yellowish next the eye (from W. Davison's notes). " Feet dull purple " 

 (Butler). 



Dimensions. " Length about 12.5 ; tail 4 ; wing 6.75 ; tarsus 1, bill 

 from gape 1.05 " (Blanf ord). 



The wing-measurements of the series in the British Museum vary between 

 6.75 in. ( = 171.4 mm.) and 7.2 ( = 182.9 mm.) and average 6.91 in. 

 ( = 175.5 mm.). Davison gives the weight of a big male as being .75 lb. 



Adult female. Similar to the male, but wanting the maroon on the 

 upper-parts. The cap of grey is perhaps even less well-defined and duller in 

 colour. 



Colours of soft parts, as in male. Davison says that the iris is " pale 

 blue blending into puce." 



" Bill leaden greenish at base and on cere " (Butler).
