 " whole under side is white ; the upper brown ; 

 " the wings partly brown, partly ash color ; the 

 " head black ; the tail not forked ; these birds

" Bill like that of the Cinereous Tern, but 

 longer and more slender, yellow to the hook in 

 the upper mandible and to the gibbous part of 

 the lower, from thence black ; length to the toes 

 and tail fifteen inches and a half, to the tips of 

 the wings eighteen inches ; breadth eighteen 

 inches ; weicrht eidit ounces and a half avoirdu- 

 pois ; the hind head and nape dusky ; at the 

 anterior angle of the orbit, a black spot, another 

 of the same behind the ear ; forehead, throat, 

 fore part of the neck, belly, vent, and rump, 

 pure white; back, scapulars, upper range of 

 coverts next the body, grey; middle series of
