 inhabiting the light soil in brushy areas are lighter, in some the breast 

 being yellowish with a few scattered spots and throat grayish. Others 

 taken near the beach on black basaltic lavas have the breast, throat 

 and mandible solid blackish and the belly plumbeous. Some of the 

 light specimens are considerably lighter above than the one described, 

 the dorsal crest being entirely light grayish and sides of belly dark- 

 spotted with the dark markings of the back arranged in transverse 

 bars.

 neck which separates them somewhat from specimens secured on

Four specimens taken at Point Christopher on black lava are dark 

 plumbeous below. Specimens secured at Elizabeth Bay on black 

 lava are also dark and of only average size.
