some purplish gloss ; base of the neck, middle of the interscapular 

 region, lower back, rump, upper tail-coverts, and entire underparts 

 dark bronze-green with an oil)' gloss ; sides of the upper back and 

 scapulars rich greenish- and ^•iolet-bronze, changing to dark ^wrpZe- 

 bronze. Two semi-erect tuft-like crests, of a dark oilj' bronze- 

 green, the first situated on the crown, the second on the nape ; 

 flanks with a large patch of white feathers. Neck and rump with 

 scattered narrow white feathers *. 



Adult ill non-hreedinij plumage. Similar to the above, but the 

 flank-patches and narrow white plumes on the neck and rump are 

 absent. The crests, though possibly dropped eventually, are 

 certainly retained for an unusually long period. An adult female 

 from the Kurile Islands in very worn breeding-plumage and in 

 moult, though almost devoid of the white flank-patches, still retains 

 both the tuft-like crests intact. Among the feathers of the crest on 

 the crown a number of young feathers are making their appearance, 

 and though the longest of these is less than half-grown it seems to 

 be a long crest-feather. The fully-grown feathers of the crest are 

 moreover very perfect and have the appearance of being fresh- 

 moulted. If the crests should prove to be characteristic of the 

 adult and not merely seasonal, the species is probably peculiar in 

 this respect. In the closely aUied P. peJagicus the crests are 

 certainly shed affpr the breeding-season. 



Tail composed of 12 feathers. 



Base of mandibles dull ashy blue, with a narrow orange stripe 

 around it, but the borders of the naked membrane ill-defined ( W. H.
