Tliis very iuterostiug' subsj)ecies differs from /'. a. aneri/tkra of Isubel auU 

 Choisenl in being paler ou tlie underside, and in having the crown of the head ranch 

 blacker, the chestnut colour being more restricted and sometimes even absent. Tlie 

 amount of chestnut varies, however, much, as sometimes there is as much as in 

 some specimens from C'huiseul and Isabel, where, however, all examples have a 

 great amount of chestnut, and mostly much mure than those from Bougainville. 



An egg was found on Bougainville in May. It is a typical Pitfa-egg, being 

 creamy white, marked all over with short lines and scribblings of brownish red and 

 with some underlying greyish mauve spots. It measures 3o-S by 2.") mm.

These three specimens agree with the description of our single type from 

 Kulambangra. The type-specimen had some white feathers, irregularly spread 

 over the head and throat ; and our statement that they were aberrational leucocistic 

 feathers proves to be correct, for our three new specimens do not show them. 

 They have, on the other hand, a narrow white shaft-stripe near the tiji of the 

 outer rectrices, distinct in two, barely indicated in the third. The wings of the 

 males measure 88 and Oo, that of the female s5 mm. Otherwise the sexes arc 

 alike. The type was probably an exceptionally large specimen, having a wing 

 of 98 mm. This rare species is not a member of the tricolor group, luit may 

 possibly be a representative of Ilk. cockereili.

These specimens agree in everything with those from (Juadule.anar and Isabel. 

 The size of the bill is somewhat variable, but not according to localities.
