Neck much shorter than the body ; bill about equal to the head, stout (length of theculmen about three ami a half times the depth through the base), the tip blunt, and the out-lines more or less convex ; tarsus shorter than middle toe with claw. Breeding plumage orna-mented by colored tufts or patches about the head, the winter plumage and the young C. cristatus. Only one species of this genus, as here restricted, belongs to North America, the occurrence offt cristatus — which for half a century or more has been included in most works on North Americanornithology, and generally considered a common bird of this country —being so very doubtful thatthere is not a single reliable record of its having been taken on this continent. For convenienceof identification, however, in case it should lie found in America, the characters of this species aregiven along with those of G.
