This is a species apparently entitled to be considered distinct from 

 the PL coronulatus. It differs by having the front and crown pinkish 

 white, and the upper part of the abdomen around the violet spot saffron- 

 yellow. The cheeks are also a dark greenish grey. First primary 

 abruptly attenuated at tip. Size the same as Pt. coronulatus. 

 Prof. Schlegel, in Mus. Pays-Bas, was the first to point out the dif- 

 ferences existing between these two birds, but did not deem them of 

 specific importance ; and Dr. Salvadori bestowed the name here 

 adopted.

The claims of this form to be considered distinct from the last 

 are based upon very slight grounds ; and it may well be doubted if it 

 should be separated from Pt. geminus. The only difference is in the 

 slightly paler crown. At best it seems to be but a local race of the 

 preceding species.

We have here, in this species and its two relatives, another 

 small section of this genus. One of their chief differences is the ar- 

 rangement of the colours on the margin of the wing, and another 

 the manner in which the terminal band on the tail is exhibited. 

 Although closely allied, the species seem to be quite distinct, their 

 geographieal distribution also giving strength to this view. 



Male. Yellowish green. Bend of wing greyish violet, mixed with 

 green. Middle of the abdomen deep orange. Vent and under tail-
