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

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

 Harrison Co. 



The earliest notice of the blind crayfish of the 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 1!!. 

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

 crayfish (Astaciis Bartoml) .... 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 from the Mam- 

 moth Cave, Kentucky," communicated by William Thompson to the Annals 

 and Magazine of Natural History ( Vol. XIII. p. Ill, February, 1S44), 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 Cave 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. The} are perhaps the first examples of their respective 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 ; ami more recently 

 :it leasl in this town, from a letter ly the Rev. Wm. Murphy, St. Muy's
