Range. - Island of Martha's Vineyard, Mass.
This species is similar to the preceding, but has the scapulars more broadly tipped with buff, the axillars barred, and the pinnated feathers on the neck pointed. It is slightly smaller than the western species. It is found on the wooded portions of the island, where its breeding habits are the same as those of the Ruffed Grouse. Mr. Brewster probably has the only authentic set of the eggs of this species. They are of a yellowish green color and are unspotted. Size 1.70 x 1.25. A number of Prairie Hens liberated on the island several years ago are apparently thriving well, and nests found there now would be fully as apt to belong to this species.
