Marsden (no. 19524), and three females, Grafton, Yolo County, September 27, 1910, It. W. M. (no. 22989), Paradise, Butte County, March 10, 1906, C. W. Bowman (no. 17980), and Santa Cruz County, January 15, 1895, G. F. Breninger (no. 26702), are referred to this race by Mr. Oberholser; and a male and female collected at Witch Creek, January 16, and November 16, 1906 (nos. 16325, 17256), by Mr. Marsden seem to me in- distinguishable. Passerella iliaca insulavis. A male taken at Nicasio, February 18, 1911 (no. 25302), and a female at Felton, Santa Cruz County, January 12, 1892, G. B. Badger (n o. 25303), Mr. Oberholser dalls this subspecies; and to it I refer also two males, Pescadero, San Mateo County, October 26, 1910 (no. 23006), and Sherwood, Mendocino County, October 13, 1908 (no. 19525), collected by Mr. Marsden. Zamelodia melanocephala capitalis. In my series of breeding male Black- headed Grosbeaks I find that 3 from Pathcoo, Chihuahua, Mexico, and 2 from the Huachuca Mountains (Palmerlee, Cochise County), Arizona, have much larger bills than 10 from different parts of California, between Humboldt and San Diego counties. In the former the exposed culmen averages 19.9 millimeters, with extremes of 19.2 and 20.5, and the depth of bill at base 15.5, with extremes of 15.2 and 15.8; in the latter these measurements are 17, with extremes of 16 and 18.3, and 14.2, with extremes of 13.5 and 15.2. In addition the Chihuahua and ttuachuca Mountain birds have the heads more solidly black. A breeding male from Walsh, Alberta, with bill of 17.6 by 14.8, one from Newcastle, Colorado, measuring 17 by 15.2, and a probably migrating male from Tucson, Arizona (May 6, 1907), with bill of 16.1 by 13.1 agree both in size of bill and color of head with California birds and not with the larger bird ascribed by Ridgway to the Rocky Mountains. Guiraca caerulea salicarius. My few Blue Grosbeaks from California, 3 males and I female from Redlands, have the small bill. which Ridgway first uoticed was characteristic of California birds. This difference seems to me of fully as much value as the different shade of blue and slightly larger size by which lazula differs from caerulea. Lanius borealis invictus. A comparison of 26 Northern Shrikes in my col- lection from the Magdalen Islands, Connecticut, New York, North Carolina and Ontario, with 17 from British Columbia, Montana, North Dakota and Colorado shows that the western birds in. the same stage of plumage have the upper parts a paler shade of gray, less vermiculation on the breast, with the white areas of wings, tail, rump and scapulars larger, as claimed for this race. A PARTIAL LIST OF THE SUMMER RESIDENT LAND BIRDS OF MONTEREY COUNTY, CALIFORNIA By J. R. PEMBEPTON and H. W. CARRIGER WITH i[AP AND FIVE PHOTOS N GLANCING over the many volumes of THE CONDOR one can not help but be struck with the fact that Monterey County has been sadly neglected by bird students. There have been published in our magazine just two general arti- cles on the birds of this region and two small notices in the field-and-study de-
