their subspecies have a wide range of variation in extent, tliough usually preserving a character- 
istic outline, although at times this also disappears. Thus we have the dusky area practically 
gone on the inner web of the outer tail feather of some of the females of cincrasceiis, producing a 
feather exactly as in nuttingi."

De.scriptions ok Nkw Birds from Southern" Mexico. By E. W. Nelson. From Proc. 
Biol. Soc. Washington XVI, Nov. 30, 1903, pp. 151-160. 
Mr. Nelson gives descriptions of thirteen new species of Mexican birds from the collection of 
the Biological Survey. One of the most remarkable of these is the Omilteme jay, Cymiolyca 
Diirabilis, from Omilteme, Guerrero. It is marked with a band of silvery white extending 
across forehead and back over the eyes behind the ear coverts to unite with a large white area 
covering the throat and under side of neck. The rest of the head is black and the body dull 
indigo blue. 
A New Grouse from C.\i,iforni.\. By P'r.vnk M. Ch.\pm.\x. From Bull. .\mer. 3Ius. 
Nat. History, XX, .Art. XI, pp 159-162, .April 25, 1904. 
Mr. Chapman has described the common grouse of the Sierra Nevada Mts. , under the name 
Deudragapus obscurus siernr, the type coming from Flcho, Ed Dorado Co. It is a much paler 
bird than p'n/ig//wsits\ and although probably derived from this form looks more like obscurus. 
The range is; “California in the forested portions of the Transition and Boreal zones, ‘east of the 
humid coast belt, and south through the .Sierras to .Mount Pinos’ (Grinnell); north to Fort 
Klamath, Oregon.” 
.Addition.^!, NoTt;s To Summpcr Birds of Fi..\thp:.\d L.\kk, with speci.\i. reference to 
Sw.\N L.^ke. By Perlev Milto.n Sii.LOw.w, Bull, University of Montana, No. 18, Biological 
Series No. 6. 1903. pp. 291-308, 5 plates. 
This paper includes a description of the physiographical features of Swan Lake, Montana, and 
under Oological Notes, additional observations on the nests and eggs of a considerable list of 
species. Under Notes on New Birds are listed with annotations eleven species not included 
in the “Summer Birds of Flathead Lake.” The paper concludes with a list of all the summer 
birds which have been observed about Flathead Lake, numbering 137. .A nest of the willow 
thrush was found in the iwanijiy area near the station. “Instead of being situated near the 
ground, it was six and one-half feet above, in an upright crotch of an oblique thorn}- sapling. 
The nest was tvpical of the willow thrush in construction, but the site was so unusual in my 
experience that I collected the owner for complete identification.” Numerous other interesting- 
notes bear witness to Air. Silloway’s careful observation and industry. 
Bird Life; Storie;.s, Book O.ne, by Cl.vrence; AIoore:s Weied, is a collection of biog- 
raphies of twenty-four common birds compiled from the writings of .Audubon, Bendire, Nuttall 
and AVilson. These four writers, as the compiler states “are especially notable for the absorbing 
interest with which they pursued the study of birds. They were all original investigators, ex- 
ploring the trackless wilderness in their search for knowledge.” Elach sketch is followed by a 
short paragraph defining the geographical distribution of the species. There are also twenty- 
four portraits from mounted specimens reproduced by the three color process. This book which 
is to be followed by two others, is intended for use in the higher grades, for which purpose it 
should prove acceptable. (Square 12 mo, 86 pages, 12 plates; Rand, AIcNally & Co.) 
In Birds from Bengue;t Province:, Luzon, .\nd erom the: Islands oe' Lubang, AIin- 
DORA, Cuvo .AND Cag.ay.ancillo (Bull. Philippine Mus. 3, Jan. 30, 1904) Richard C. McGregor 
records all Identified species of birds collected or observed on recent expeditions to the above 
localities. The paper includes zoographical notes, accounts of undescribed plumages and notes on 
the rarer species. 
Bird-Lore: for March-.April is an unusually attractive number, and contains three general 
articles, all very readable. The splendid series of warbler plates is continued, there being two in 
this number, the frontispiece representing the Canadian and Wilson, and the second plate the 
black-throated green and golden-cheeked. There are three pages of Notes from Field and Study, 
and the .Audubon .Society Section concludes with Educational Leaflet No. 8, The Alarch Hawk , 
by William Dutcher, illustrated by L. .A. Fuertes. E'or Teachers and Students contains the 
third instalment of The Migration of Warblers by W. AV. Cooke. Under “The AA'arbler Book” 
the editor asks for cooperation of bird students in securing information regarding the habits of 
warblers, as noted in another column of this issue.
