This bird greatly resembles Sterna Cantiaca : it is 

 of the same size as that bird : its beak is about an inch 

 and a half long, thick, strong, and angulated on the 

 under mandible like that of a Gull ; it is wholly 

 black : the upper part of the head, taking in the 

 eyes, is black, and extends far down the back of the 

 head and part of the neck ; sometimes there are a 

 few white feathers on the crown : the general colour 

 of the plumage of the upper parts of the body is 

 cinereous ; the tail and its upper coverts are similar 

 to the back, but the outer feather on each side is 

 white : the quills are hoary, with the tips of the first 

 five spotted black, for upwards of an inch : in other 

 respects the wings are similar to those of Sterna Can- 

 tiaca, except that part of the inner webs which is 

 white, does not quite reach the margin, the very edge
