Southward, there were scattered stands of creosote bush, but the main vegetation was a mesquite scrub. We observed large numbers of western kingbirds apparently in migration. Nighthawks and Turkey Vultures, also apparently migrants, were also seen in good numbers. An injured nighthawk was picked up along the road (see Russell's catalog for locality), and Russell collected a brown towhee, a Say phoebe, and an immature long-billed dowitcher, the last a lone individual associated with a small flock of 'peeps,' probably western sandpipers, and feeding in a muddy shallow pool along the road. Also saw vermilion flycatchers, black vultures, Audubon caracaras. Oct. 3 Travelled from Hermosillo to Guaymas, reaching the latter after 11 A.M.

We left the mesquite scrub outside of Hermosillo and passed into a desert scrub which continued to the ocean. In Guaymas we contacted the American consul, Mr. Webster, and then proceeded
