Two or three specimens of this singular bird were in the collection which exhibited the first examples of the 
genus thus established ; subsequently, however, two or three other species have been made known to science, 
fully confirming the propriety of separating the group. 
Of the manners and habits of the Hypsipetes psaroides we have to regret that no information has hitherto 
reached us. We may be led to conclude from the general form, the pointed wing, the broad and forked tail, 
and the shortened tarsi, that its natural situation is semi-aérial,—. e., that it resides among trees, but ob- 
tains its food principally in the air. 
We have reason to believe that the sexes exhibit no difference in their plumage. The head is slightly 
crested with narrow black feathers. The general plumage is of a cinereous grey, becoming paler on the under 
parts, the tips of the wings and the tail excepted, which are of a brownish black ; a few black feathers 
occupy the sides of the face; the beak and feet are orange. 
We have figured an adult bird of its natural size.
