801 



POLYSTICTA, Eyton. 



Polysticia, Etton, British Birds, 1836. Type .inas StelUH, Gm. Sufficiently different from Polysticte, Smitli, 



1835. 

 Stelleria, Bonap. Corap. List, 1838. Same type. 

 Macropus, Nuttall, Man. 11, 1834, 450. (Preoccupied.) 

 Eniconella, Gray, Genera, 1840. 

 Ch — Bill_quite similar to that of Histrionicus, but rather broader at the tip, which is more abruptly truncate, and witli the 

 nail less prominent. Scapulars slightly curved outwards ; tertials much more so. Tail pointed, about half the wing. Feathers 

 of head and neck short, and velvet-like. Tail of 14 feathers. 



This genus, in many respects, appears most like Histrionicus; the bill, however, is broader 

 and more truncate ; the nail scarcely distinguishable. The feathers of the cheek extend rather 

 more forwards, anteriorly. The feet are much smaller in proportion. The feathers of the 

 head are much shorter, fuller, and more erect. The outward curvature of the tertials is much 

 greater and more conspicuous, involving to some extent the scapulars. There is much resem- 

 blance in coloration to Lampronetta and Somateria.
