Mayhew 1963 Oct. 19 Glamis area, Imperial Co., Calif. This morning we drove to the eastern edge of the Algodones Dunes, 2 miles S.E. of Glamis. Here we found two pools that obviously had been produced in the September storm, since they both contained large numbers of adult fairy shrimp (Thamnocephalus platyurus). These shrimp were quite green when captured, due to green objects (zoochloellae?) within their appendages. None of the green was in the gut. Several young Scaphiopus couchi were found hopping about near the pools as well as up on the adjacent sand dunes. We returned to UCR at 1420 after a trip of 446 miles. I forgot to mention that I found the first giant red velvet mite (Dinothrombium) that I have seen in the Colorado Desert. It was walking across the mud by the sand dunes 2 miles S.E. of Glamis. Lloyd said that others probably would emerge today also, but we didn't have time to wait and see. Oct. 20 All the tadpoles I brought back to the laboratory turned out to be Bufo punctatus. Two of them metamorphosed; all the rest died.
