THE CONDOR Vol.. X 



throat and fore chest also black; sides of head and neck, patch on chest bordering 

 black area behind, and median abdominal region, dull white; whole back (includ- 

 ing scapulars and rump) and sides, flanks, and crissum, pure smoke gray, without 

 any of the buffy cast characterizing Parus gambeli gambeli; wings and tail mouse 

 gray, edged with lighter. 



Measurements OF Type. — lycngth (of skin), 132 mm.; wing, 72.5; tail, 66; 

 tarsus, 19; depth of bill, 4; culmen, 10.5. 



Distribution. — The mountains of southern California (breeding in the Tran- 

 sition and Boreal zones), and adjacent valleys in winter. 



Remarks. — The characterization of this new subspecies is based upon an ex- 

 amination of 95 skins of Parus gambeU. Thirty-six of these were loaned me by 

 the United States National Museum, thru Dr. C. W. Richmond, Acting Curator, 

 Division of Birds. The remaining 59 are from my own collection, and include 46 

 from southern California all of which are fairly referable to Parus gambeli bailey ce. 

 Forty-seven skins from northern California, Oregon, Washington, and Rocky 

 Mountain region from New Mexico and Arizona to Montana, are all Parus gam- 

 beli gambeli. One skin from Fort Tejon and others from Mount Whitney and 

 further north in the Sierra Nevada are plainly P. g. gambeli. Two skins from 

 Mount Pinos, Ventura County, are indeterminate, one being juvenal, and the 

 other a worn adult. 



The race baileyce is larger and grayer than the northern and Rocky Mountain 

 race gambeli. These characters are altogether constant in fully adult birds. An 

 occasional baileyce in first annual plumage has the sides not as clearly gray, being 

 faintly overcast with brownish, and so is like gambeli. But the bulkier bill then 

 serves as a criterion for recognition. I believe I would have no trouble in assort- 

 ing even immatures of the two races. 



I take pleasure in naming this well-marked new chickadee for Mrs. Vernon 

 Bailey (Florence Merriam Bailey), whose accurate and pleasantly-written accounts 

 of many of our birds form an important component of the ornithology of the west.

NOTES FROM THE DIARY OF A NATURALIST IN NORTHERN 



CALIFORNIA ^ 



By JOHN F. FERRY 



THE following notes were made while carrying on field-work in northern Cal- 

 ifornia for the U. S. Biological Survey, under the direction of C. Hart Mer- 

 riam, during the summer and autumn of 1905. The writer was associated 

 from July 21 to August 9 with Mr. A. Sterling Bunnell, then a medical student in 

 the University of California, and from September 18 to November 3 with James H. 

 Gaut, at that time a regular employee of the Survey and a field- worker of much 

 experience. 



a Author's Note : 

 This article is written from notes as they were jotted down in a field diary, and at the time served merely as 

 memoranda from which extensive reports were sent in from each locality visited. No efifort was made to identify 

 material in the field, as such material, including mammals, birds and plants, was sent in with field data only. Hence 

 the article must lack in completeness and thoroness , but still a conscientious effort has been made to keep out 

 of error and to make positive assertions only when they are j ustified. Credit is given to others whenever possible. 



Altitudes were taken by two aneroid barometers. I am indebted to the Biological Survey for a number of edenti- 

 fications as noted in the text.
