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

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

 more brightly coloured and in some clutches the markings are much 

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

 bright reddish-brown, the markings being ofteu 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 

 Zonotriehia leucophrys and its allies and should possibly be referred 

 to one of those species. They measure from '7 to '86 in length, and 

 from '55 to -GS in breadth.
