No. 156 of Part II. 



Male. Upper plumage glossy bluish green ; a line of pure white runs 

 on each side of the forehead from the nostrils to the upper eyelid, but 

 not extending over the eye; lores black; rump white; upper tail 

 coverts blackish brown ending with bluish green ; tail blackish brown ; 

 quills blackish brown, a few of the outer secondaries narrowly edged 

 with white ; entire under plumage pure white ; bill and feet black. 



Length about 4J in.; wing 3f ; tail If; tarsi T 7 g. 



The female differs only in being rather smaller. 



On a second comparison of this species with P. leucoptera, I 

 found they were not the same, in general plumage they are 

 much alike, but in leucoptera the secondaries are broadly 

 marked with white, whereas in this they have only a mere 

 edging of that color ; it also resembles P. Meyenii, Cab., but 

 differs from both species, in having a white line running from 

 the bill to the eye.
