17. PACHTCEPHALA. 205 



Specimens in the plumage described by Peale as P. albifrons are 

 like the adult male, but have the frontal band white, the chin 

 blackish grey, the throat pale greyish white ; the upper part of 

 breast and throat are divided by a semicircular white band, which 

 band is the result of the terminal half of the feathers of the upper 

 breast being white ; thighs dark olive-brown. 



A younger specimen from Samoa is of the same colour, bi;t has 

 the throat and chin still blackish brown-grey, only a few feathers 

 being tipped with greyish white, but the white semicircular band is ■ 

 already visible. 



They are apparently female birds. 



The supposed females of this species in the collection of the 

 British Museum are of a somewhat larger size than the males ; and 

 this would induce one to believe that they belong to a different 

 species ; but their size is of no importance, because the measure- 

 ments of this species given by Peale himself show that his P. albi- 

 frons are the smallest and P. icteroides the largest, whilst those 

 specimens in the British-Museum collection which agree with P. 

 albifrons of Peale are the largest.
