This last spécimen is of some interest, as the head is green with only a few violet 

 feathers at the base of the bill, while a blue spot can be seen on the occiput, resembling 

 that of the female, but much smaller and only feebly indicated. Although Salvadori (Orn. 

 Pap. III p. 9.) describes several young maies with green crown, he never mentions this female 

 characteristic in the maie. A young maie in the Leyden Muséum, apparently in the same 

 stage of development as my bird, has the crown perfectly green, without any blue.

The first mentioned of the two exactly agrées with the types of Schlegel in the 

 Leyden Muséum. The smaller wingcoverts on the right side are tipped with purple and the 

 same occurs in one of Schlegel's spécimens from Japen (Jobi). Without any doubt my bird thus 

 belongs to P. i. jobiensis and so do those from German N. Guinea, mentioned by Madarasz 1. c.
