and the more-extensive barring and spotting of the under parts, 

 which separates these forms from kiskensis. The under parts 

 are noticeably grayer than those of kiskensis, the latter being 

 more tawny. But meligerus is the darkest one of the group. 



There is a single specimen from Agattu Island — a mummified, 

 extremely dark, immature bird. The fact that this single speci- 

 men is immature makes it impracticable to identify it with cer- 

 tainty, though one would expect it to be meligerus. Four 

 specimens from Buldir Island, 2 immature and 2 in worn breed- 

 ing plumage, are referable to meligerus — this is most interesting, 

 because Buldir (the most isolated island in the Aleutian chain) 

 is a lone island, far from either Kiska or Attu. 



Family TURDIDAE 



Turdus migratorius: Robin 

 Tardus migratorius migratorius 



We found robins common at Snag Point, Nushagak River, on 

 May 25 and 26, 1936. We saw them at Seward on May 21, 1937. 

 Osgood (1904) says — 



A few robins were seen near Iliamna Village, and one specimen was taken 

 there July 15. From this point on to the upper Chulitna River robins were 

 seldom seen, though once in a great while we heard their familiar note. 

 They were quite abundant in small flocks about Swan Lake August 25, and 

 considerable numbers were also seen near there in the brush and young 

 timber around the base of the "Portage Mountain." 



Cahalane (1943) reports — 



I found that robins were numerous in the willow-cottonwood-spruce thickets 

 on Naknek River at Big Creek on the early morning of September 4. They 

 were probably migrating. I did not see any after leaving the river on that 

 date and passing into the lake region in the National Monument. 



Gabrielson noted a few robins on Afognak Island on June 15, 

 1940, and he found them to be common at Dillingham on July 17. 



There are specimens in the National Museum from Nushagak, 

 Kakwok, and Lake Iliamna. 



Ixoreus naevius: Varied Thrush 

 Ixoreus naevius naevius 



At least six specimens from Kocliak Island were examined. 

 These were collected by F. Bischoff, in 1868 ; by C. H. Townsend, 

 in 1888; by A. K. Fisher, in 1899; and by R. H. Beck, in 1919. 

 All these specimens are typical naevius, thus suggesting that this
