Similis P. discuro, sed pileo toto et cervice cum capitis 

 lateribus viridi-cyaneis; gutture toto, pectore et abdomine 

 viridi-cyaneo lavatis. 

 Adult male. General colour above grass-green, becoming 

 clearer green on the lower back and rump, and decidedly 

 brighter on the upper tail-coverts; curious dusky frecklings 

 are seen on the feathers in a strong light ; wing-coverts green, 

 the median and greater coverts a little brighter ; bastard- 

 wing and primary-coverts green, with a bluish tinge inter- 

 nally; quills black, externally green, subterminally with a 

 blue shade, and fringed with yellow, the first primary exter- 

 nally blue ; two centre tail-feathers bright green, with a black 

 shaft and racket at the end, which is black edged with green ; 

 remainder green, internally blue, and with a broad band of 

 black at the ends ; tail blue underneath ; entire head and 

 nape, as well as the sides of the face, ear-coverts, cheeks, 

 throat and sides of neck verditer-blue, overspreading the 

 under surface of the body, which is otherwise light green, 

 but yellow towards the vent and under tail-coverts, the latter 

 being yellow washed with green ; under wing-coverts and 

 axillaries bright green ; lower primary-coverts and inner web 

 of quills pale blue, blackish externally and at the tips of the 

 primaries. Total length 12*4 inches, culmen 0'8, wing 6"1, 

 tail 2*8, long feathers 5*6, tarsus 0'5. 



Young birds differ from the adult in being entirely green, 

 without any of the beautiful verditer-blue shade on the head 

 and neck ; the wing-coverts and secondaries edged with 

 yellowish green ; under surface of body pale green, yellower 

 on the throat, and bright yellow on the under tail-coverts, 

 washed with pale green.
