REFERENCES l-'KOM TABLE OF SEA-BIRDS PECULIAR TO TIIK NORTH PACIFIC. 



(a) In Japan, only on Yezo and the Knrils. 



(b) In Japan, only on the Kurila. 



(c) In Japan, only on Yezo and the Kurils. 



(d) In Japan, only on the Kurila. 



(e) Has not been found north of Yezo in Japan, and Tras not obtained by Mr. 

 Stejnegerin Kamtschatka, though he has included it in his " Synopsis of the Birds re- 

 ported to inhabit Kamtschatka" (Bull. U. S. National Museum, No. 29, 1885), on the 

 authority of Dr. Dybowski. On the American coast it breeds as far south as Cali- 

 fornia, ranging to Lower California in ■winter. — A. O. U. Check List, p. 78, 



(/) This, like the preceding species, is only found in Japan, in Yezo and the south, 

 and is not included in the Kamtschatkan list. It was given in the "American Orni- 

 thologists Union Check List" as "from Washington Territory northward," but this it 

 appears was an error which has been pointed out by Mr. Stejneger (vide antea, p. 524;. 

 The nearly allied species S. antiquu8 is a more northern bird. 



{g) Japan collections contain no examples from the Kurils, and Mr. Stejneger missed 

 this species at the Commander Islands. He has lately, however, received a bird from 

 Kamtschatka which he considers B. perdix Pall., which hitherto has been used as a 

 synonym of ^. marmoratus, and he believes Japan specimens will be referable to that 

 species. 



{h) Mr. Stejneger considers the record of this species too uncertain to include it as 

 an inhabitant of Kamtschatka. B. craveri and B. hypoleucus are both southern species, 

 and not likely to occur on the Asiatic side. 



(t) Cepphus cario seems, as Mr. Stejneger remarks, "to be restricted to a very lim- 

 ited area." Its occurrence on the eastern shore of Kamtschatka is uncertain, while in 

 Japan it is only determined with certainty on Yezo, all Kuril specimens being C. 

 columia. 



(j) Q^) These are both of somewhat uncertain determination in Yezo and the Kurils, 

 some specimens having been referred to Briinnich's Guillimot of the Atlantic, and 

 lately Mr. Seebohm ("Ibis," 1885, p. 3fi4) mentions "an almost complete series" of 

 intermediate forms. Mr. Stejneger's conclusions on his Bering Island examples, how- 

 ever, leave no doubt as to the two Pacific sub-species being there. 



(Z) Of this cormorant Mr. Seebohm says (" Ibis," 1885, p. 271) : "I have skins of 

 five adults, besides those of several immature birds. The dated adults are Amoy, 

 February; Amoy, April; Hakodadi, February * * *. Like the Common Cormorant, it 

 has fourteen tail-feathers, but it is a slightly larger bird; the gorget is profusely 

 streaked with greenish black, and the scapulars and wing-coverts are bronzy green, 

 narrowly margined with black, as in the Shag." 



(m) («) Both these species were obtained by Mr. Stejneger on the Commander 

 Islands, and are included in the Japan list. P. persjncillatus Paxl. has been omitted, 

 as Mr. Stejneger considers it exterminated from those islands. 



(o) This species should possibly not figure in a list of peculiar North Pacific birds, 

 depending, as it does, only on a single specimen obtained on Yezo. It is represented 

 on the American Pacific coast hj Fregata agi/iZa (Linn.), which also inhabits the 

 Atlantic. 



(p) This has appeared in Japan lists until now as L. delaioarensis Ord and L. niveits 

 Pall., but Mr. Stejneger, after a critical examination and comparison of his speci- 

 mens collected in Kamtschatka, arives at this name as the correct one, saying : "This 

 Asiatic form is in some respects intermediate between ddawarensis and californicus.'" 



(q) Mr. Stejneger believes the Japan bird No. 70 to be the Pacific representative 

 of X.mariJHfS of the Atlantic, described by him from Kamtschatka in The Auk, 1884, p. 

 231, as L. schistisagus, which occurs also in Alaska. 



(?•) The Pacific Kittiwake, pointed out by Mr. Stejneger as a sub-species from Kam- 

 tschatka, includes that of the Pacific American coast, and doubtless that of Japan.
