Known Localities. — Kentucky: Mammoth Cave and other caves in. Ed- 

 monson Co. Indiana : Wyandotte Cave, Crawford Co. ; cave in Bradford, 

 Harrison Co. 



The earhe.st notice of the blind crayfish of tlie Mammoth Cave occurs 

 in the Proceedings of the Academy of Natural Sciences of Philadelphia, 

 Vol. I. p. 175. In the record of the meeting of the Academy on May 24, 

 1842, the donation of a specimen is thus acknowledged: "A white eyeless 

 crayfi.sh {Astaeus Bartonil) .... from the Mammoth Cave, Kentucky, about 

 2\ miles from the entrance. Presented by W. T. Craige, M. D." 



From a " Notice of the Blind Fish, Crayfish, and Insects fi-om the Mam- 

 moth Cave, Kentucky," communicated by William Thoinp.son to the Annals 

 and Magazine of Natm'al History (Vol. XIII. p. Ill, February, 1844), I quote 

 the following : — 



" At a meeting of the Belfast Natural History and Philosophical Society, 

 Jan. 17, 1844, Mr. Thompson, the President, called attention to specimens 

 of the Blind Fish, Crayfish, and Locusts from the great Mammoth C;ive in 

 Kentucky, procured in the month of May last, specially for the Society, by 

 the kind attention of our townsman, Gordon A. Thomson, Esq., on his visit 

 to the cave. They are perhaps the first examples of their resjiective species 

 brought thence to Europe. 



" The cave itself is popularly known from having been described in 

 'Chambers's Edinburgh Journal' for 1838, Vol. VI. p. 234 ; and more recently, 

 at least in this town, from a letter by the Eev. Wm. Murphy, St. Mary's
