moore. Accipiter velox September 8, 1929 A male of this species was slawn- [illegible] upon the southeast slope of San Jacinto Peak, 10,300, being pursued by a band of Clarke's Grouse. San Jacinto Mtns. Riverside Co., Calif. Later on a male of this species (Prob- ablely the same individual) was seen pursuing small birds in and out among the underbrush at 8,300 ft about a quarter of a mile away from where the first hawk was seen. December 20, 1924 At Black Rock Spring, 3,500 ft., San Bernardino Co.; 18 mi. N.E. of Whitewater Station Riverside Co. California a hawk of this species was observed pursuing a mountain quail. The quail was fleeing with an excessive rate of speed down a forty mile an hour wind. When first seen, the quail was approximately one hundred yards off the ground and the hawk close behind and slightly higher. Neither seemed to be gaining ground on the other, and as the two approached the observer the hawk was shot, and the quail released high up on the slope among the pinyons and junipers. The hawk upon being skinned, proved to be in fine condition, and had evidently fed well on the large quail for some time.
