ARANEIDA EPEIRID^E. 67 



Blatchley (1896, 203) found this species to be the most abundant 

 spider of Indiana caves. He took 2 or 3 immature specimens from 

 Mayfield's Cave. According to Emerton (1902, 190) this arachnid "lives 

 in caves and similar cool and shady places in various parts of this country 

 and also in Europe."

Four individuals of this species were taken within the cave. All 

 were found during the winter and all were near the door except one 

 which was found suspended by a single thread of web at " 10."

 the mouth of Donaldson's and Twin caves at Mitchell.

Fairly abundant in fall and winter from near the mouth to "5." 

 These spiders appear in the cave by early fall and stay until early spring. 

 I have not found them in spring or summer and think they merely 

 hibernate in the cave. They are not very active in the fall and during 

 the winter are quite sluggish. One very large female was observed to 

 have moved less than a foot during two months of winter. Another 

 remained in nearly an identical spot throughout the winter. They are 

 found on the roof or wall and have no web. I found this species hiber- 

 nating under logs in the ravine below the mouth of the cave. This 

 spider lives habitually along the margins of streams under stones, and is 

 known from Alabama and the Eastern United States.
