tlie feathers (if tlie niiiicr liack broadly edged with red, and the tail-fentliors, nvoii 

 the central jiair on their outer welis, are bine or bluish. The}- would therelore seim 

 to belong to /'. xaiithix/fni/s, which ma}- be snbspocifically diil'erent from /'. irterntix. 

 Unfortunately, however, the habitat of the type oi xantlioc/enj/s is unknown, and so 

 is the distribution of the true ictcrotis, if that is really distinct. We have specimens 

 which must be true icterotis, but their locality is uncertain. The wings of the 

 adult (supposed) xantliofifw/s measure 140 to 143 mm. The rump is dull pale 

 green, not greyish. 



More information about these yellow-cheeked parrakeets is sadly wanted, and 

 we hope that Mr. North or other Australian ornithologists will soon discuss them 

 fully — not from vague observations, but with the help of properly collected series 

 of skins from all parts of Australia where they occur.

The series of this rare Parrot is very interesting. Though these facts are not 

 all absolutely proved by moulting specimens, I can only come to the following 

 conclusions : — 



The red-crowned examples, in wliieli all tiie feathers of the crown have wide 

 yellowish red or pure red margins, are immature. The specimens with the feathers 

 of the uiider-surface quite yellow, with only a very narrow ashy grey margin and 

 the utmost base pale grey, are more or less immature or females, which do not seem 

 to get the black-based breast-feathers of the adult males. Younger birds have the 

 feathers of tlie back jiale yellow with a large round black spot in the middle, while 

 adult birds have this spot so much extended that the feathers may be described 

 as black with a yellow border. Females are considerably smaller than males. The 

 young and females have often some red spots on the lower throat and in tlie middle 

 of tlie abdomen.
