LARUS OCCIDENTALIS Audubon. 

 WESTERN GULL. 



The Western (iull was common about San Francisco Bay when wdj 

 left, and several were seen following the ship at different times until 

 we reached Puget Sound, after which we did not meet with this 

 species. 



LARUS VEGiE Palmen. 

 VEGA GULL. 



This gull was rather common in Qnalga Pas-,, neat- Unalaska, and 

 was seen again, though not in any numbers, in Avacha Bay, Kam- 

 chatka. I have no other records. 



LARUS CALIFORNICUS Lawrence. 

 CALIFORNIA GULL. 



The California Gull was common about the hay when we left San 

 Francisco, and individuals were seen following the ship until we 

 reached the mouth of the Columbia River. 



LARUS BRACHYRHYNCHOS Richardson. 

 SHORT-BILLED GULL. 



This species was rather common off the mouth of the Columbia 

 River, and was also seen in Puget Sound. 



LARUS HEERMANNI Cassin. 

 HEERMANN'S GULL. 



Heermann's Gull was seen occasionally in San Francisco Bay on 

 the day of leaving, but was not met with subsequently. 



LARUS CRASSIROSTRIS Vieillot. 

 JAPANESE BAND-TAILED GULL. 



We first met with this species in Hakodate harbor, where it was. 

 abundant about the shipping. I was surprised n<>t to sec it in Vol- 1 

 cano Bay and about Mororan, but it was common along the west 

 coast of Nipon, especially in Xanao harbor, about Sado Island, the 

 Oki tslands, Matsushima, along the Korean coast . and in the Korean] 

 Straits. A lew were seen at Nagasaki ami Kagoshima, and it was 

 common in Tokyo Bay and about Yokohama. 1 also saw a lew at j 

 Otaru (Yezo), and it was common in Aniwa Bay, Sakhalin. When: 

 we returned from Sakhalin to Hakodate in October it appeared to be J 

 just as common as it had been in June and July. 



One of the birds observed at Hakodate had the central pair of 

 reel rices entirely white, making a conspicuous break in the black tail I 

 band.
