In most of the genera of this family,the first plumage of the young resembles that of the adult,the occasional exceptions found in the Eook being perhapsexplicable on the hypothesis before suggested {supra page303) ; but in that view the genus next to be described mustbe deemed less developed and differentiated, retaining as domost of its members that unmistakable mark of youth—aspotted plumage—to the end of their 330 PA USE RES.
