NEW NORTH AMERICAN BIRDS. . 95 



SUBSPECIFIC CHARACTERS. Similar to P. dilophus floridanus, 

 but with the nuptial plumes pure white, instead of black. Similar 

 in coloration to P. dilophus cindnnatus, but much smaller. Hab. 

 Pacific coast of United States, from California (Farallone Islands) 

 to Cape St. Lucas ; Revillegigedo Islands, Western Mexico. 



This is the small southern form of cincinnatus, being, like the 

 latter, distinguished by its white nuptial tufts, but differs in its 

 much smaller size, in which respect it agrees closely with floridanus. 

 P. dilophus thus may be separated into four races, the two southern 

 ones {floridanus and albociliatus) distinguished from their northern 

 representatives (dilophus and cintinnatus) by smaller size alone, 

 while the western forms (cincinnatus and albociliatus} appear to 

 differ from the eastern ones only in the color of the nuptial tufts, 

 which seem to be always white or much mixed with white, instead 

 of black with little or no admixture of white.
