D. Zweifel 1953 Journal 6mi WSW Tres Adjuntas, 8500', Durango, Mexico July 10 No reptile hunting at this camp has been rather poor. Only a single garter snake (T. enana) has been taken, and two rattlers (C. pricei). We have found few Selagosus. S. janowi, S. poirnetti and S. grammicus are all present, but with the exception of S. grammicus have been most difficult to find. Only a single S. janowi has been caught, and two thus S. poinetti. The latter were associated with logs or stumps, a departure from the usual rocky habitat. The weather has been such as to inhibit reptile activity. Usually the clouds form in mid to late morning and cut off the sunlight before the area is sufficiently warm to stimulate much activity. An exception was the day yesterday (yesterday) when the cloud held off until early afternoon, and the collecting picked up greatly (one rattler, 11 skinks, 1 Phrynosoma). The series of skinks was particularly valuable in that it enabled us to identify the jewel juveniles collected at the El Veguel camp, verifying them as a new state record, and a range extension of close to 200 miles. Birds identified at this site were red backed juncos, "black-capped" chickadee, pygmy nuttatch, white breasted nut- natch, spotted towhee, acorn woodpecker, red-shafted flicker, Steller's jay, man sp?, flycatchers sp?, Blue-throated hummingbird, white-eared hummingbird (?), and solim
