Typhlichthys subterraneus Girard was discovered at Bowling Green, Kentucky, 

 and later found in Mammoth Cave. For a time specimens of this species and of 

 Amblyopsis found a ready market at Mammoth Cave, and this probably has had 

 much to do with its later scarcity in this place. It was subsequently caught in 

 other caves, to be sold at Mammoth Cave. The author has taken it in Roaring 

 River of Mammoth Cave, where it was occasionally found swimming freely, but 

 more often under large rocks to be brought out only by tapping the rocks with the 

 net handle or one's foot. The difficulties in collecting this species (as well as other 

 material) in Mammoth Cave arise from the great extent of the cave and the in- 

 convenience of transporting collecting apparatus to the remote places where alone 

 these fishes are to be found.
