were extremely plentiful in the large swales and basins that are so common a part of the geology of the area East of Pleito Canyon. There could have been as many as fifty of these mammals standing or running about one den of holes that would not have been more than seventy- five feet square. At 4:30 p.m. I left the San Emigdio Ranch and returned home via Bakersfield, California. A map I was formally using, according to my present map and California Place Names "Gudde", had misspelled the name Pleito that is given to the second large canyon to the east of the San Emigdio Ranch headquarters. A smaller canyon between these two named Pleitito Canyon was also misspelled. I have been using the spelling Plieto and Plietito Canyons which according to the above sources is wrong. In the future the correct spelling, as above, will be used.
