Lee Arnold 1937 Meotoma cinerea Horse Canyon, 5800 ft, Zabrum Dr., Washoe Co., Nevada May 28, While going through the mines on the north wall of the canyon in search of bats I found several nests of this species. In every case they were at the far end of the mine. They were located on a ledge or on the ground. The tops of the nests were open and in superficial appearance the nests appeared to be much like that of a jay. There was numerous sign of recent habitation of rats in the form of -- soil moist from urine, feces, fresh clippings of various shrubs. Two of the species of shrubs I am taking in to have identified. It seems that the rats use these nests to sleep in both day and night (when not active). When they hear someone approaching they probably squeeze back into one of the many fissures in the rock and hide until the coast is dear. Otherwise I would have encountered some of them along the mine tunnel or in the nests. In every case where nests were found there were also such fissures where they could squeeze. In several of these fresh drop- ings and cuttings were found. One of the miners gave me an adult ? which had died in the mine where they were working. I saved the skull of this specimen
