tnniljle will be greatly lessened. In every species there i.s a more or les.s 

 decided ocliraceous tinge to the crissal region (sometimes extending forward 

 over the ilanks) ; except in criasidis, in which the lower tail-coverts and anal 

 region are deep cliestnut. In autumn and winter tins ochraceous tint be- 

 comes very much deeper, as well as more i)revalent, than in spring and 

 summer; the whole plumage becomes softer, the colors more pronounced, 

 and the markings more distinct, than when faded and worn in summer.
