16 MEMOIRS OF THE NATIONAL ACADEMY OF SCIENCES. 



A "cave rat" was described to me by Mr. Eothrock as having been seen in the main Wyan- 

 dotte Cave. It was said to be of the same color as the domestic rat, but with the body longer, 

 somewhat like a weasel's; the whiskers are longer than those of a rat, and "the ears are nearly 

 twice as large." It is probably a Neotoma. 



BRADFOED CAVE. 



[16 miles from New Albany.] 



This is a type of many caves in southern Indiana. A brook (temperature 55°) flows through 

 it, and after leaving the mouth of the cave is tenanted by Cambarus rusticus and " possibly 

 Putnami" (Faxon, Eevision, 114, 119.) Near it is Loughmiller's Cave. Both of these caves I 

 visited in company with Dr. John Sloan, who kindly devoted a day to their exploration. 



The following species inhabit it : 



Cecidotcea stygia. Pack. 



Cambarus pellucidus. (Tellkf. ) Abundant in the stream in the cave. 



Degeeria cavernarum Pack. 



Ceuthophilus sloanii Pack. 



Anophthalmus tenuis Horn. More abundant than I have ever seen other species elsewhere. 



CAVES AT CLIFTT, BAETHOLOMEW COUNTY, INDIANA. 



For the following account of these caves I am indebted to Dr. John Sloan : 



Since I wrote you I have visited the caves at Clifty. The mouths of the caves are about 200 yards apart, each 

 with a small stream of water running through. The larger cave is easy of access, containing very little insect life, 

 but some very fine blind-fishes and some blind crayfish. The former presented a rotundity which encouraged me to 

 expect an increase from them, which has not happened yet. Temperature of the water, 56°. The smaller cave sup- 

 plies a mill and has deep water at the mouth. It occupies a higher lerel than its neighbor and is less capacious. I 

 went up about 200 yards on a raft of timber, where I came to rapids with still water above; being unable to lift our 

 raft over, and the water above being too deep to wade, we were obliged to return. I saw no blind-fishes, but caught 

 three eyeless crayfishes in the edge of the upper pool. Temperature of water, 60°. About 40 feet within the larger 

 cave I found, under stones, some little leeches ? with parasites upon them. 



MAYFIELD'S CAVE. 



This cave has been visited by Mr. O. H. Bo'.lman, of Bloomington, Indiaua, and it is situated 

 near that town. It contains Cambarus pellucidus (Tellkf.), Ccecidotcea stygia Pack., Crangonyx sp. 

 A Machilis occurred within a few rods from the entrance. 



CAETEE CAVES. 



These are situated in the hilly portion of northeastern Kentucky, in Carter county, not far 

 from Cincinnati. They are in limestone and are comparatively small grottoes, without floe stalac- 

 tites, and have not been very fully explored. There are three caves, visited by Professor 

 Shaler and myself — Zwingle's, Bat, and X Cave— and a small cave used as a pantry by the 

 proprietor of the hotel. They are well watered, having streams passing through them. Professor 

 Shaler found the temperature of the water (May 15) both of Zwingle's Cave and Bat Cave to be 



48° Fahr.
