Larus Hutchinsii Richardson. ( Coues, Pr. Acad. Nat. 

 Sc. Phila., 1862, p. 294.) — Hutchius' Gull. Snow- 

 white Gull. I am much pleased, to find in the collection 

 an excellent example of this species of Richardson's, which 

 I have recently revived, as above. The specimen agrees 

 entirely with others in the Smithsonian Institution from 

 various localities, upon which I based the species. The 

 bird is rather smaller than glaucus, and pure white all 

 over, including the wings ; the shafts of which are yel- 

 lowish. On the upper tail coverts and scapulars are some 

 very faint, nearly obsolete transverse bars of light gray- 

 ish brown. On the under tail coverts these bars are some- 

 what better defined. The plumage of the breast and 

 belly has a slight clouding of grayish, doubtless, with the 

 bars above mentioned, indicative of immaturity. The 

 bill is yellow, its terminal third black. The legs and 

 feet appear to have been dusky flesh-color. 



We can avoid recognizing this bird as a valid species 

 upon only two hypotheses. One is, that it is an albino ;
