eastern boundary where we should expect intergrades. I once followed a bird 
near Columbus whose yellow had the convincing glow of gold below 
(hypochrysea, gold below); and a specimen exists in the Oberlin College 
Museum which is undoubtedly referable to this subspecies.

tive; bears some resemblance to D. maculosa below, but smaller and otherwise 
quite different.

AFTER D. kirtlandi the Prairie Warbler is with us the rarest of the 
genus. Its normal range lies much farther south, and those which pene- 
trate our state are to be regarded only as pioneers or as adventurers without 
fixed habits. Professor Jones has seen single males at Oberlin on two dif- 
ferent occasions, but there are no records for Ontario; and it seems prob- 
able that those birds which reach the Lake Erie shore in spring turn south- 
ward again before settling for the summer. 
On the 11th of June, 1903, I came across a singing male on a hill-top 
near Sugar Grove, at the point shown in the illustration. The bird moved 
restlessly from place to place, singing indifferently from the depths of black-
