BIRDS—LARIDAE—LARUS CHALCOPTERUS. 843 
Journal fiir Ornith. Juli, 1855, p. 281, applies so well to the adult specimens before me, that I 
have no doubt of their being the same. His account, in which no measurements are given, is 
very concise and is as follows: 
“Resembling ZL. glaucus altogether, with the exception of the wing fag IY which in this 
species are ashy gray with round white spots on the points.” 
He puts Z. glaucopterus, Kittlitz, as a synonym, but gives no references where to find the 
descriptions of either author. 
The omission to make references to the original descriptions of species prevails throughout 
Dr. Bruch’s very valuable monograph ; it would have added much to its usefulness if this had 
been done when citing authorities,

The only notice of this species I have met with is in Bruch’s Monograph of Gulls, referred to 
above ; his description is as follows : 
‘¢Resembles very much L. leucopterus, except in the wing feathers, which are ash gray with 
round white spotted points; the young are dark gray like L. glaucopterus.”’
