Laru s glaucus . 
Mass. 
Spent most of the forenoon at Fresh Pond watching the 
water fowl assembled there. (All with one exception were 
Herring Gulls and Ducks). The exception was a Larus glaucus 
in the " hut oh ins i 11 plumage, i.e. wholly white without trace of 
blue in the mantle or of mottling anywhere. I could see this 
distinctly with the glass [double telescopic glasses] for the 
bird was not far away and in a good light. I could also see 
that its bill 'was larger than that of the Herring Gulls which 
were swimming near and flesh-colored with a dark band near 
the tip. Tiie bird spent most of the time during whioh I 
watched it in sleeping although it also preened its feathers 
once or twice.
