504 bulletin: museum of comparative zoology. 



Characters. — Similar to A. madagascariensis madagascariensis 

 (Bod(Iaert) of eastern, northern, and central Madagascar, but slightly 

 larger; the green parts of plumage much bluer less yellowish green, 

 the rump about cobalt-green, some of the feathers and the upper 

 tail-coverts tipped with benzol-green; wings (except primaries which 

 of course are dusky) and back, about zinc-green; belly and under 

 tail-coverts, turtle-green; throat and breast purer grey due to the 

 almost total absence of yellowish on the bases of the feathers of these 

 parts. 



Measurements. — Adult male (two specimens) wing, 91-95; tail, 

 55-56; tarsus, 12-13; culmen from cere, 11. 



Remarks. — This very bluish form is in all probability confined to 

 extreme southwestern Madagascar. It was referred to by Salvadori 

 (B. M. Cat., 20, p. 508) from Ankafana, s. Betsileo, and from 

 Rodrigues (introduced). There are two specimens in the U. S. N. M. 

 received from the Paris Museum collected by Besson in 1889. but 

 labeled simply Madagascar.
