 186 THE CONDOR Vol. XVII American Museum of Natural History, his collection and my own, and especially with the birA on which his description of the young of the Kumlien Gull was based; also by Mr. Louis H. Porter and myself with the yomg bird reported in The Auk, xxm, p. 37. The result has been always the same, the only noticeable difference between the Pacific Grove bird and the two Kumlien's Gulls from the east being that the primaries of the former are a clearer, somewhat darker, gray, as they are much less worn and faded, and that it has acquired many feathers of the pale pearl-gray mantle of the adult. It is a smaller bird than any speci- men of Larus glaucescens I have seen, especially in bill, tarsi and toes, and the mantle is paler, the shade of Larus kumlieni. Little is known about this species, which was at first confused with Larus glaucescens, but it certainly seems im- probable that it should wander to California, as it has so far been recorded only from the North Atlantic. Mr. Oberholser, chiefly for this reason, considers my bird only an abnormal Glaucous-winged Gull with an unusually small bill. Marila collaris. Four females: 1, Pacific Grove, December 21, 1911; 3, Colusa, (1) December 5, 1913, and (2) January 5, 1914, H. W. M. (nos. 23719, 25995-7). Arenaria interpres interpres. The young female Turnstone (no. 11717) taken on September 8, 1904, at Pacific Beach, and recorded in THE CONDOR, VII, p. 141, as this race, has much darker upperparts and breast, and less rusty on wing-coverts, than any of a series of 10 young female A. i. norinella taken on the Atlantic coast in. August and September. In 5 females taken in Florida in December the rusty has disappeared by fading and attrition, but the upperparts ae even paler than in the early fall birds and very much paler than the Pacific Beach bird. The latter closely resembles young A. . interpres from Oceanica in the collection of Dr. Dwight taken in November, and agrees with them in having the tips of the rectrices white and not pale rusty as in A. i. morinella. 0tocoris alpestris merrilli. Eight males and five females, Dos Palos, Mer- ced County, November 2-13, 1908, H. W. M. (nos. 19615-27). 0toootis alpestris pallida. A male Horned Lark from Palm Springs, Feb- ruary 16, 1913, A. Brooks (no. 26696), is called O. a. ammophila by Mr. Ober- holser, and a female taken at Redlands on February 13, 1903, H. W. M. (no. 8396), O. a. leucansiptila. These birds are noticeably different, but both are grouped under O. a. pallida in the A. O. U. Check-List, and I have seen no birds from the type locality of the last. Corvus corax clarionensis. Four Ravens collected on San Clemente Island by Mr. C. B. Linton, young male, October 8, adult females, January 24 and March 5, and young female, October 8, 1907 (nos. 18515-8), differ fully as much in wing, tail and length and depth of bill from five Ravens from Humboldt Coun- ty, California, Montana, North Dakota and Colorado, as the latter do from five from Alaska and Greenland, while in the ratio between length and depth of bill . the San Clemente birds are more like Ravens from the far north than those from other parts of the northern United States. This would indicate that if C. c. principalis is recognized, C. c. clarionensis should be; but, as none of my skins of C. c. sinuatus are from anywhere near tile type locality, it may be that they are not fair representatives of that race, but intermediates with C. c. principalis. Passerculus sandwichensis nevadensis. Three Savannah Sparrows from Trinidad, Humboldt County, California, taken August 21, 26, and 31, 1909 (nos. 20699-701), Mr. Oberholser refers to nevadensis; and four from Witch Creek, male, November 21, 1904 (no. 12121), and three females, December 11, 1903 (no. 10215), October 31, 1904 (no. 12120), and January 25, 1906 (no. 16296), and
