6 FAUNA OF MAYFIELD'S CAVE. 



sp., and a Machilis. Bollman (1888, 405) mentions the occurrence of 

 Conotyla bollmani McNeill within the cave, and Faxon (1889, 621) notes 

 the occurrence of Cambarus peUucidus (Tellkampf). W. P. Hay visited 

 the cave in 1891-92 and described a new subspecies, Cambarus peUucidus 

 testa, from it (1893, 283). Blatchley (1896, 127-128), during his explor- 

 ations in 1896, visited the cave, wrote a short description of it, and 

 mentioned the occurrence of 11 species within it, namely, Quedius spelseus 

 Horn, Anopthalmus tenuis Horn, Leria {Blepharoptera) latens ( Aldrich) , 

 Leria (Blepharoptera) speciis (Aldrich), Sinella\{Degeeria) cavernarum 

 (Packard) , Conotyla bollmani (McNeill) , Spirostrephon lactarium (Say) , 

 Meta menardi (Latreille) , Cascidotea stygia (Packard) , Crangonyx gracilis 

 (Smith), and Cambarus peUucidus (Tellkampf). 



The bibliography at the end of this paper will give a sufficient index 

 to the work done heretofore on the cave animals of North America. 

 A few papers, however, deserve special mention. 



Packard's Cave Fauna of North America (Packard, 1888), based 

 upon material collected and explorations made by himself and others in 

 Kentucky caves and to some extent in southern Indiana and Virginia 

 caves, is a most notable and excellent work on American cave animals. 

 It discusses the life histories and habits of such cave animals as were 

 known to its author. 



Cope paid a two days' visit to Wyandotte Cave in 1872, and his Report 

 on the Wyandotte Cave and its Fauna (Cope, 1872) is an interesting 

 account of the fauna of this cave and contains a discussion of cave life 

 in general. 



Blatchley, State geologist of Indiana, with a party of four assistants, 

 made a five weeks' exploring and collecting trip to nineteen of the most 

 important caves of Indiana during the summer of 1896. An admirable 

 account of the work done was published (Blatchley, 1896). His paper 

 includes a discussion of the formation of caves, short descriptions of 

 the caves explored, and a list of the animals collected, together with 

 descriptions of new species and notes on the occurrence, habits, and 

 interrelations of the various cave animals. These publications* are the 

 nearest approach to an ecological study of a cave fauna heretofore 

 attempted. Eigenmann (1897-1905) and others have contributed much 

 to our knowledge of the structure, habits, and origin of cave animals. 



I am indebted to C. H. Eigenmann and W. J. Moenkhaus, of Indiana 

 University, for encouragement and valuable suggestions on working up 

 this paper. C. H. Eigenmann personally furnished me with much of 



*The following papers ought also to be mentioned in this connection: Call, 1897; 

 Garman, 1889; and Ulrich, 1901.
