TEN INDIANA CAVES. 113 



washed into this and other caves in which it was found 

 by the heavy rains of the season. The other and 

 smaller species, Cizcidotcea stygia Packard, is a true 

 subterranean form and was the most common crusta- 

 cean noted in Indiana caves. It was usually found 

 singly, swimming or crawling slowly through the 

 water of small cave streams, and was 



ave easily picked up with a pair of forceps.

Its body is flattish like that of a sow- 

 bug, but is oblong and more slender, 

 reaching a length of one-third of an 

 inch. These crustaceans probably fur- 

 nish much of the food for the blind fish 

 and crayfish which often inhabit the 

 same streams with them. 



Three hundred feet from the cave en- 

 trance the lower passage ends abruptly 

 in a room fifty feet high and ten feet 

 wide, the sides converging in an angle to 

 form the roof. On the left, about twelve Fig. 27 

 feet from the floor, is an arched opening, tfea 8tv(lia - 

 and through it comes a roaring sound of falling 

 water. With difficulty one climbs a slippery bank 

 and, passing through this opening, finds a most mag- 

 nificent scene for so small a cave a great cylindrical 

 pit or shaft, twenty feet in diameter and sixty feet 

 high, down which, on the farther side, falls a stream of 

 water. A large bowl-shaped cavity, twelve feet deep, 

 has been worn by the falling water in the limestone 

 below the level at which the pit is entered. Descend- 

 ing into this, it was found that the stream flows out 

 through a passage to the left too low for exploration.
