The ring-hilled gull is not uncommon on Puget Sound, where I obtained several specimens. 
It has been my rule, as far as possible, in this report, to confine myself, in treating of the 
various species of birds, to those which have been collected by me, and, after careful comparison 
with others in the Smithsonian collection, have been found strictly entitled (so far as yet known) 
to the specific name assigned to them. In the present instance, however, I feel justified in 
departing from the rule, as, although my own specimens were lost before reaching Washington, 
I, nevertheless, feel sufficiently certain that they were identical with the old Larus zonorhynchus, 
the present species. This is verified by the presence of a specimen in the Smithsonian 
collection procured by Dr. Kennedy on Puget Sound, and also by a comparison of the notes 
taken by me on a couple of skins which agree, with the exception of the toothed bill, with the 
following description by Mr. Ord of the species which is quoted by Mr. Lawrence in the 
General Report: “Length, 19| inches; extent, 46; upper mandible with four indentations or 
blunt teeth; lower with three; corner of mouth and eyelids, bright vermilion; head, neck, tail, 
and beneath, pure white; wings, back, and scapulars, blue ash; weight, 19 ounces.” 
My own specimen, (marked 478,) an adult, measured almost the same as the one described 
by Mr. Ord, being 19 inches in length and 46.50 in extent. The legs and feet were of a 
gamboge yellow, with a slight greenish tinge; bill of the same color, with a black zone near 
the tip; margin of eyelids vermilion ; angle of mouth bright reddish orange. Another agreed in 
every respect except in dimensions, which were larger. 
This species seems to be subject to great changes in color of plumage, feet, and bill, at 
different ages. Its habits are not different on Puget Sound from those of its brethren on the 
eastern coast, and have been so well described by Nuttall and others that I can add scarcely 
anything. Near Port Steilacoom they are very abundant during the cooler months, at which 
season they are very common on the marshes and flats at the mouths of the different rivers 
emptying into the sound. When an individual is wounded, his comrades, like other gulls, hover 
over and circle around the victim as if impelled by motives of curiosity or compassion. 
Frequently at this time the others can be readily brought down by the same gunner with his 
undischarged barrels, but the occasion must be quickly seized because the sympathizing birds, 
which at first are bewitched, as it were, by the accident to their companion, soon lose the 
charm, and, becoming more Avary, enlarge their circles, and, ascending higher and higher, soon 
place themselves out of shot range.—S.
