Although I have no corresponding series of specimens 

 before me^ it is not difficult, with the aid of various descrip- 

 tions, to follow the development of P. fasciatus in its dif- 

 ferent stages of growth. The young bird is at first entirely 

 green, with yellow-tipped feathers below, yellow under tail- 

 coverts, and a grey (sometimes pale yellowish) band at the 

 end of the tail. The magenta feathers of the cap first begin 

 to sprout at the forehead ; soon afterwards the yellow-tipped 

 feathers upon tbe breast arc lost, the orange under tail- 

 coverts and yellow cross-band of the tail are assumed, and 

 the chestnut-red of the abdomen begins to make its appear- 

 ance, when the bird becomes P. apicalis, Bp. The remaining 

 yellow-tipped feathers of the abdomen are now lost, and the 

 purplish -black band separating abdomen and breast is pro- 

 duced, and the bird shows the plumage of P. pictiventris, 



* Mr. Elliot appears to have overlooked the fact that J. Verreaux, in 

 a letter to Drs. Finsch and Hartlaub, declared this bird to be without 

 question the young of P. fasciatus (F. & H., Orn. Centralpolyn. p. 290 ; 

 Finsch, J. f. 0. 1870, p. 46), but he was aware that the type in the Paris 

 Museum is not fully adult.
