 Ch — Bill quite similar to that of Hislrionicus, but rather broader at the tip, which is more abruptly truncate, and with the 

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

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



This genus, in many respects, appears most like Ilistrlonicus ; 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.
