Two adult males and a young female were obtained at Genzan, 

 Apr. 26. This species is very common in all bays, harbours and 

 river mouths in Corea and S. Manchuria. 



82. Rhodostethia rosea (Macgill.). 



Hime-kubiwakamome. 



An adult specimen in non-breeding pi ut age partly winter and 

 partly summer dress was presented to me by Mr. S. Wakiyama. It 

 was collected at Sötö Bay, near Port Arthur ; date unknown. This 

 measurement is as follows : total length about 310 mm., exposed culmen 

 20 mm., wing 246 mm., tail 112 mm., difference of length between 

 middle and outer tail feathers 23.5 mm., tarsus 29 mm. This little and 

 rare gull is undoubtedly a new addition to the avifauna of Manchuria. 



83. Sterna bergli, subsp. 

 Oajisashi. 



I have a specimen of this species, said to have come from an 

 island about 72 miles north of Chemulpo, Keiki Distr., July 5, 191 7. 

 It is an adult not yet in full nuptial plumage: the forepart of crown 

 white with some black feathers, and the bill chrome-yellow with dark 

 parts in the distal third of its length. The entire dorsal side, including 

 wings and tail, is much paler than in 5. bergli boreotis, the back and 

 tails being nearly white or faintly greyish. Size also smaller exposed 

 culmen 59 mm., wing 325 mm., tail 163 mm., tarsus 25 mm.
