No. 9. Sex not noted, Karaga Village, August 2], 1897. 

 Colour of bill, both inside and outside, yellow ; of gape, 

 eye-ring, and soft parts of interior of moutli crimson ; 

 of legs liglit yellow; of claws a peculiar tint of yellowish 

 horn. The descriptions of the colours having been taken from 

 the note made by me at the time, 1 have not cheeked the 

 nomenclature, and it will be noted that the parts of the 1896 

 bird called vermiliou are in 1897 called crimson. There is 

 proliably, however, some variation in the tint of red of these 

 parts, for in Stejneger^s description of L. kamtschatchensis 

 (Bp.) the eye-ring is called vermilion in one and dull 

 reddish in another specimen. 



No. 10. Juv., Karaga Village, August 21, 1897. Colour 

 of bill a mixture of horn- and flesh-colour; of iris hazel; 

 of legs and feet pale flesh ; of claws horn. 



It is rather refreshing to meet a species like this and the 

 next, which, although occurring at the opposite ends of 

 the PaliBarctic Region^ cannot be divided into subspecies. 

 Dr. Stejnegcr had only one specimen of L. canus from 

 Kamchatkan regions, and that was from Bering Island, 

 and not from the mainland, to which the bird would there- 

 fore appear to be new. But I suspect that Dr. Stejneger 

 would call my specimen L. kamtschatchensis (Bp.), a form 

 which is not accepted by our British authorities, and which, 

 if distinguishable, must be remarkably close to L. canus. 

 L. kamtschatchensis is said to be not common in Kamchatka, 

 where, however, it probably breeds. My Karaga specimens 

 extend the range of the bird (under whieliever name it is 

 preferred to designate it). The breeding-place of Gulls 

 found on the Karaga river was probably one belonging to 

 this species, and the specimen no. 9 must have been bred in 

 North Kamchatka. Among my birds from the Commander 

 Islands is a straggler of L. canus in first plumage (according 

 to Mr. Howard Saunders), obtained on Copper Island, 

 August 20th, 1896.
