INVERTEBRATES OF THE CAVERN 185 



the floor of the cave near the entrance of Yeitso's Den, 

 at the last trace of outside light. It was found on a 

 piece of fresh meat which had been used as insect bait 

 and which had evidently attracted it. 



A small false scorpion of the genus Chelanops, not yet 

 specifically identified, was collected in the cave near the 

 east elevator shaft, one hundred and seventy feet below 

 the surface and in almost total darkness. It was on the 

 dry beds of guano, where mites and young spiders may 

 have furnished it food, for they are predatory arachnids 

 related to the scorpions.
