~\ 39. Prioniturus verticalis, sp. n. (Plate VI.) 



A considerable series of adult birds of both sexes from 

 Bongao, Sibutu, and Tawi-Tawi. 



It is very interesting to find here a new Parrot closely allied 

 to the Celebean form P.flavicans. It has the sides of the 

 neck and hind neck paler than the rest of the back, but 

 merely of a yellowish-green colour instead of the golden 

 olive, or, as Salvadori calls it, the " olive-brown " colour of 

 the hind neck, which, in P. flavicans, is also found ex- 

 tending across the fore neck and chest. P. verticalis has the 

 under surface of the body entirely yellowish, washed with 

 green. The crown of the head is of a silvery cobalt, ex- 

 tending over the nape, and in the centre of the crown is 

 a scarlet spot. In P. flavicans the crown is darker, the 

 blue is of a lilac tint and only extends to the occiput, while 

 the median spot is crimson. 



The female differs from the male in being emerald-green 

 all over, and wanting the verditer-blue on the head as well 

 as the scarlet spot on the latter.
