J.D. Anderson 1956. 59 Journal Dec. 1. Trip to Stockton, San Joaquin Co., Cal. This trip an attempt to locate a possible locality for Ambystoma macrodactylum. 1 specimen exists in the V.C. Dent of Zool. at Davis collection. It was collected along Country Club Blvd. 1/4 mi. from San Joaquin river. A careful search along the present day Country Club Blvd. produced nothing. The Country Club still exists but has no habitat which looks like Ambystoma habitat. The surrounding area has been developed into a residential area. No suitable Ambystoma habitat now seen. There is considerable pest mites in this area (V.C.D.Z. spec. collected from plants) but no ponds exist there now. One possibility exists in this area. Along the Calaveras River about 1 mile east of the College of Pacific campus we saw several areas along the stream bed which look like good Ambystoma habitat. Much of the stream margin is reminiscent of over where A. tigrinum & A. opacum breed in Cape May Co. New Jersey. This story may be occupied by A. tigrinum here in Stockton. It also could be a channel for A. macrodact., since the Calaveras River comes from macrodact. country in the Sierra Nevada.
