The local population, so far as known, repre- sents the coastal group of races of A. coeru- lesens and is now included with the Sacramento Valley race, superciliosa. Some intremixture may occur, however, as a typical example of A. c. nesudae was collected a first-year female, in the fall near Butcllffe on the west side of Pyramid Lake. Continued south eastward along the shore of Pyramid Lake to the mouth of the Truckee River. Scattered white pelicans seen along the shore. They breed on Anaho Island in Pyramid Lake. An interesting area of dunes was observed which town is north of Wadsworth, located at the "head" of the Truckee River. The dunes result from wind action on the sediments of Pleistocene Lake Lahonton (which also filled Mullens Gap and Warm Springs Valley, where old shore lines can be seen). In one example of stabilized dune vegetation, the dominant shrubs were Dalea polyadenia, Atriplex canescens, Tetradyxia comosa, Tetradyxia glabrata, Eurotia lanata, and Grayea spinosa.
