16 THE GENUS PORPHYRIO AND ITS SPECIES, 



Vieill. It appears to differ from the last-named by having the 

 head blue, and the throat and chest a lighter blue, and in the 

 grass green legs and feet, these last being red in its relative. 

 In size the two appear to be about the same, the dimensions 

 of the present species being fully equalled by those of speci- 

 mens of cyanocephalus before me. Mr. Gould states it was 

 abundant at Swan River and also the lakes and rivers around 

 Perth and Freemantle. The male is somewhat larger than 

 the female. The following is Mr. Gould's description of 

 the type, now I believe in the collection of the Philadelphia 

 Academy of Natural Sciences : — 



" Head, neck, and all the under-surface deep blue ; sides of 

 the face, front of the throat and chest, greenish blue ; back, 

 wings, and tail, brownish black ; shoulder, and edge of the 

 wino-, and outer margins of the primaries, greenish blue; 

 under tail-coverts, white ; irides, bright red ; bill, red ; legs, 

 grass green, except the knees (?), lower part of the tarsi 

 and inside of the feet, which are dark greenish grey. Total 

 length, 18 inches; bill, 175 ; wing, 10'5 ; tail, 4"5 ; tarsi, 

 3'5 inch.
