“aa 372 University of California Publications in Zoology |VoU-24 There were a few varied thrushes breeding on Nine-mile Mountain, in the dense woods just below timber line. An adult female (no. 42629) collected there on July 23 had laid part of its set. The two specimens mentioned above, the only breeding birds col- lected, belong to the coastal subspecies, naevius. At the end of the summer, migrating varied thrushes of another sort appeared. The first was seen September 1, a week later they were abundant, and there were numbers in the woods about Hazelton (mostly feeding in the sumac bushes) when I left. September 26. These migrating varied thrushes, judging from three males collected (nos. 42630-42632), were of the subspecies J. n. meruloides. Sialia currucoides (Bechstein). Mountain Bluebird A summer visitant to the lowlands, not abundant but of general distribution in the more open country. Present and in pairs when we arrived at Hazelton, the last week in May. The first young bird out of the nest was seen July 4. In August the species disappeared from sight, but early in September a few migrating bluebirds appeared from time to time, and they continued to be seen until September 22, when the last was observed. Three specimens collected, all adult males (nos. 42633-42635). CHECK LIST OF THE MAMMALS . Sorex personatus personatus I. Geoffroy. . Sorex obseurus obscurus Merriam. . Microsorex eximius (Osgood). .
