hardly need comparison with the eggs of any other of the Jays, 

 having a much purer white ground-color and a very different style 

 of spotting. 



The nest above described was found on the horizontal branch of a 

 nut-pine, toward the top, but only nine or ten feet from the ground. 

 Both our other observers' accounts indicate a similar position for 

 the nests, and it is probable that very little variation in this respect 

 is to be looked for. 



Later Mr. Parker writes that he has since found a second colony 

 in another portion of the same range of hills, where " thousands " 

 breed. Unfortunately he was too late for the eggs.

 region washed faintly with dull green ; cheeks pale buff. Supra-orbital

 and crissum, most pronounced on the pectoral region, and intensifying
