BOLYSTICT Ay Ey ton: 
Polysticta, Eyron, British Birds, 1836. Type nas Stellerit, Gm. Sufficiently different from Polysticte, Smith, 
1835. 
Stelleria, Bonar. Comp. List, 1838. Same type. 
Macropus, Nurrati, Man. II, 1834, 450. (Preoccupied.) 
Eniconetta, Gray, Genera, 1840. 
Cu —Bill quite similar to that of Histrionicus, but rather broader at the tip, which is more abruptly truncate, and with 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.
