Some eggs of the West-American Tree-Sparrow resemble those 

 of S. monticola, but the majority of those in the Collection are 

 more brightly coloured and in some clutches the markings are much 

 larger. The ground-colour is pale green, spotted aod mottled with 

 bright reddish-brown, the markings being often dense and confluent 

 at the broad end, where they sometimes form an imperfect cap. 

 Underlying the surface markings are many smears and clouds of 

 purplish-grey. Eggs of this species, if all are correctly identified, 

 vary greatly in size. The larger ones closely resemble the eggs of 

 Zonotrichia leucophri/s and its allies and should possibly be referred 

 to one of those species. They measure from •? to -86 in length, and 

 from "55 to -63 in breadth.
