Adult. Similar to H. semica'ruleus, but larger ; bill and feet rich 

 sealing-wax red. Total length 9 inches, culmen 1"8, wing 4, tail 

 2-7, tarsus 0-45. 



Youn<i. Similar to the yonng of H. semicceriileus ; bill blackish. 



This is nothing but a large insular race of U. semica'ruleus, scarcely 

 worthy of recognition. The characters which I formerly depended 

 upon to separate the two species, such as the whiteness of the head 

 &c., are of no value, as is proved by the larger series of skins which 

 I have since been able to examine.
