Phanetta subterranea Emerton. A few were collected 300 feet 

 from the entrance of Spring Cave (a wet cave one fourth mile 

 west of Marengo Cave). These were found under flat rocks and 

 rotten boards on the floor in damp places. They were in com- 

 pany with thysanurans. Several were caught in all parts of 

 Little Wyandotte; however, none nearer the entrance than 75 

 feet. A few of these were observed under flat stones, but most 

 of them were seen on the base, or in the cracks of stalagmites. 

 Those on the base were usually running about, while those in the 

 cracks were hanging to the underside of their tiny webs. 1 The 

 snare is a flat sheet. It generally droops a little in the center. 

 The meshes are very minute and the number of attachment 

 threads depends on the surroundings. This species is a swift 

 runner and the young are entirely white. Small diptera, thy- 

 sanurans and myriopods were rather plentiful. This arachnid 

 was abundant in Saltpeter Cave under flat rocks in moist places. 

 They could not be affected by carbide light. Diptera and thy- 

 sanurans were common. 



Anthrobia mammouthia Tellkampf was found only in Mam- 

 moth Cave. Eleven specimens were caught. Since I had to 

 keep in company with a crowd of cave visitors who were led by 

 a guide, I was unable to stop more than one or two minutes at a 

 place. However, I found specimens at various localities and 

 undoubtedly they may be taken at any place in the cave where 

 there is sufficient moisture. They were always found under flat 

 rocks, on old mouldy paper and among debris. One small white, 

 disk-like cocoon was observed under a flat stone. These spiders 

 are rather active, not fast runners, and are not difficult to catch 

 for they cling tightly to the rocks and to one's fingers. They 

 vary in color from white to a light brown. 2 In most places 

 insect life seemed to be comparatively scarce. Perhaps these 

 arachnids eat old mouldy paper, remains of lunch and the limited 

 number of small insects. 



Meta menardi Latreille. They are rather common at the 

 mouth of Spring Cave. One was observed in Saltpeter Cave and 

 five were caught at the end of the main channel in Mammoth 



1 Blatchley says these are wandering spiders and spin no webs. " Indiana Caves 

 and their Fauna," Rep. Ind. Geol. Surv., XXI., p. 204. 



2 Hitherto they have always been described as being only white.
