at Iliamna Bay July 10, and proceeded westward and northward to Lake 

 Clark, then westward and southward to Nushagak, on Bristol Bay, and 

 then eastward again across the peninsula to Cold Bay, near the mouth of 

 Shelikof Strait. A map of the region traversed indicates the principal 

 physical features, and another map the faunistic features, while eleven 

 half-tone cuts furnish views of scenery and vegetation in a hitherto 

 almost unexplored region. About twelve pages are given to a general 

 description of the region, and four to a consideration of its life zones, 

 which are plotted on the accompanying map. The journey was made 

 chiefly by canoe. The special interest of the region consists in the fact 

 that it constitutes the meeting ground of the Hudsonian and Arctic life 

 zones, the boundary between which, being the junction of the treeless and 

 timbered regions, Mr. Osgood is now able to define with considerable 

 accuracy. " The Arctic occupies the main part of the Alaska Peninsula 

 southwest of the vicinity of Naknek Lake, together with a narrow strip 

 northward along the coast of Bristol Bay and Bering Sea ; the Hudsonian 

 stretches over the region to the northward on the mainland." 



The annotated 'List of Birds' numbers 134 species, based in part on 

 specimens taken by the late C. L. McKay, and his successor J. W.John- 

 son, some twenty years ago (1 881-1886) when stationed as United States 

 Signal Service observers at Nushagak (formerly Fort Alexander), and 

 not hitherto published, except to some extent incidentally. With the 

 exception of the work of McKay and Johnson, nothing had been done in 

 this region before Mr. Osgood's visit in 1902. It is fortunate to have 

 their records, resting on specimens in the National Museum, thus 

 rescued and brought together with those of Mr. Osgood. The McKay- 

 Johnson specimens here mentioned appear to represent about 111 species, 

 while Osgood appears to have taken or positively identified about 108, 

 respecting many of which he has extended and very interesting field 

 notes. — J. A. A. 



Nelson on New Birds from Mexico. — Mr. Nelson has recently de- 

 scribed ' four new birds collected by Mr. E. A. Goldman during the 

 spring and summer of 1904 in southern Mexico, mostly in the state of 

 Chiapas. They are: (1) Porzana goldmaui, generally similar to P. 

 noveboracensis, from the Valley of Toluca, Mexico; (2) Empidonax 

 fulvifrons fi/sciceps, from Chiapas ; (3) Arretnenops superciliosus chia- 

 pensis ; (4) Tehnatodytes palustris toluccnsis, from Valley of Toluca. —
