fuller at the middle. The very rare Masters' Parrakeet probably 

 differs in much the same way. 



Adelaide Parrakeet (Platycercus Adelaides). 



The male is brighter in colouring, more distinctly marked, and its 

 tail is less green than that of the female. His beak, seen from 

 above, is generally fuller, and much broader at the base. 



Yellow-rum ped Parrakeet (Platycercus fiaveolus). 



Only the male is sexed in the Museum series, but, judging from 

 the form of its beak, it should differ from the female in the same 

 manner as P. elegans. 



Yellow-bellied Parrakeet {Platycercus flaviventris). 



The male is brighter than the female, not generally so green ; its 

 beak is altogether fuller when viewed from above. 



Mealy or Pale-headed Rosella (Platycercus pallidiceps). 



I found no sexed specimens in the Museum, but what I take to be 

 the male is larger, altogether more brightly coloured, and has a fuller 

 beak when seen from above than what is presumably the female. 



Blue-cheeked Parrakeet (Platycercus amathusia). 



Only one male in poor condition sexed. So far as I could judge, 

 it would seem to differ from the female in its fuller beak. 



Brown's Parrakeet (Platycercus brenvni). 



No examples were sexed in the Collection, but the sexes probably 

 differ as in other species of the genus. 



The Red-mantled Parrakeet (Platycercus erythropeplus) is now 

 known to be only a hybrid between Pennant's Parrakeet and the 

 common Rosella. 



Rosella or Rose-hill Parrakeet (Platycercus eximius). 



The male is brighter in colour, larger, its beak longer and a little 

 broader at base than in the female. The late Mr Abrahams on one 

 occasion called my attention to a pair of these birds, and asked me 

 if I could see a difference in marking between them. After careful 

 examination I said that the only difference I could discover was 

 that one had a small round green spot on the crimson of the nape, 

 which was wanting in the other. " Exactly," replied Mr Abrahams ; 

 "that is an invariable character of the female." Subsequently, on 

 talking it over with Mr Camps, the well-known judge of these birds, 

 he expressed doubt of the validity of this character, saying that the 

 colouring of the nape was very variable. A study of the skins in
