TEN INDIANA CA VES. 119 



Entering the cave, one finds himself in a commodious 



room, 10 feet high and 48 feet in width, the floor of 



rock, covered in places to a depth of two or three feet 



with alluvial drift. Fifty feet back this narrows to 



12 feet in width and a short side passage puts off to 



the left, in which a number of the cave salamanders, 



Spelerpes maculicaudus (Cope), were found. This 



handsome batrachian was taken in a number of the 



caves visited and doubtless occurs in all Indiana 



caverns which contain streams of water or damp 



rooms near the entrance. In life it is a

ous black spots, which, on the back 



and sides, vary much in size and shape. The body is 

 quite slender and reaches a total length of 6J inches. 



It is usually found clinging to the walls within 150 

 feet of the entrance of the caves, especially in crevices 

 and crannies just above flowing streams or pools, but 

 never in the water. While its eyes appear as large 

 and normal as those of allied terrestrial species, its 

 sense of sight seems to be limited. It remains quiet 

 when discovered and shows little fear until touched, 

 when it scrambles deeper into a crevice or beneath 

 some fallen rock on the floor. Even when a candle 

 is put within a few inches of its head it does not move 

 until it feels the heat. Its food probably consists of 

 such insects and small crustaceans as are found along 

 the margins of the streams. 



Back 180 feet from the mouth, the main passage of 

 the cave is 6J feet high by 6 feet broad, the stream-on 

 the floor being about three feet in width and three 

 inches deep. Farther on this stream deepens and
