SOME NOTES ON THE FLORA AND FAUNA OF 
MAMMOTH CAVE, KY! 
By R. ELrLsworTtH Catt, Pa. D. 
In 1889 there was published by the general government 
Dr. A. S. Packard’s “Cave Fauna of North America, with Re- 
marks on the Anatomy of the Brain and the Origin of the 
Blind Species,” which constitutes the most complete treatise on 
cave animals which has appeared in this country. In that 
work there were listed eight genera and nine species of Infu- 
soria, three genera and species of Vermes, four genera and 
species of Crustacea, eight genera and species of Arachnida, 
one of Myriopoda, twelve genera and fourteen species of Insecta, 
and two genera and species of fishes, all from Mammoth Cave. 
Dr. Packard also adds a list of seventeen forms said to be liv- 
ing temporarily in the cavern, most of which are listed on the 
authority of others. Of these one, Spelerpes or cave salamander, 
is listed on the uncertain authority of one of the guides. Ex- 
cluding this list of seventeen, which includes three forms of 
felix which most certainly came in from without, after death, 
and in floatwood, there remains a total of forty-one species. 
Seven of these are uncertain either in their generic or specific 
relations, as appears from the mark of doubt which is added 
to them. Of many of the forms concerning which there is no 
manner of doubt there are excellent descriptions and figures. 
It is not my present purpose to speak of the forms which 
were known from Mammoth Cave prior to my own period of 
study, except in the most incidental manner. On the contrary, 
it is designed only to speak on the additions which more care- 
ful investigation has brought to light. 
In the study of this new material the writer has been assisted 
by the following gentlemen, whose names are mentioned both 
that the fullest credit may be given them and that their high 
authority may attach to the determinations of the several forms
