MEMOIRS OF THE NATIONAL ACADEMY OE SCIENCES. 15 



I had the pleasure of exploring several of these caves myself a few years ago, and was especially interested in one 

 that did not seem to have been named, hut that certainly deserved it, as well as others that have been admired in 

 priut. From a great gateway, perhaps 80 feet wide, the passage dwindled to a point where we could barely' staud 

 erect. This colossal trumpet magnifies the human voice to a deafening volume ; and the name of the Trumpet 

 Cave would not be inappropriate. A large swift stream issues from Blue Spring Cave near Mitchell, -whose current 

 at high water is said to sweep completely across the White Rivor, into which it empties. It has been explored for about 

 3 miles, and contains great basins cut down 100 feet into the rock and overflowing with limpid water. (Pp. 123-125.) 



Dr. John Sloan also wrote us in 1873 as follows regarding this river : 



Did you ever hear of Lost Eiver? It is a stream of considerable magnitude which formerly ran upon the 

 surface of the 'ground, and at spring floods still fills the upper as well as lower channel. It sinks into the ground at 

 various points and again rises to the surface seven miles below, as is proved by sawdust from the mills upon it above. 

 It has crayfish above the sink with eyes; within the subterranean passage without and with eyes, pellucid. 1 

 intend soon to explore it below, as I have recently above. There is too much water to get to its under-ground channel 

 before June. The bullheads are found mostly in cave streams. 



Dr. Sloan again visited Lost Eiver in July of the same year, and under date July 22, 1873, 

 wrote ine as follows : 



I went in the interior 60 miles on the 10th instant, for the purpose of procuring some eyeless fishes before their 

 spawning season. I crawled a long distance into a muddy cave until I reached the under-ground channel of Lost 

 River, which I found very high and as thick as gruel with mud; of course, I could see no fishes. I caught some 

 eyeless beetles and some with eyes, which I send you for names. Next day I went into another cave, where I secured 

 three Amblyopses and five crayfishes, C. pellucidus. It has been too wet during the spring and summer to do anything 

 in wet caves. 



The specimens of beetles came during my absence from Salem, and in some way were over- 

 looked or mislaid and not named, with the exception of a large Asellus communis, which was 

 bleached nearly white, though with distinct eyes. It is broad, the telson broad, and the antenme 

 are unusually stout, but it has preserved the exact shape and sculpturing of specimens of the 

 normal form and size received from Indiana. 



LIST OF THE ANIMALS OF THE WYANDOTTE CAVES. 

 Crustacea : 



Cauloxenm siygius Cope. Parasite on blind-fish from a well near Wyandotte Cave. 

 Caecidotcea stygia Pack. 

 Cambarus pellucidus (Tellkf. ). 



Myriopoda: 



Pseudotremia cavernarum Cope. Also a single specimen of var. Carterensis Pack. 

 Arachnida : 



Oribaies ? lucifugus Pack. Little Wyandotte Cave. 



Phalangodes flavescens (Cope). 



Linyphia snbterranea Emerton. 



Insecta: 



Degeeria cavernarum Pack. 



Campodea coolcei Pack. 



ATachilis sp. (Cope.) 



Ceuthophilus stygius Scudd. 



Ceuthophilus sloanii Pack. Little Wyandotte Cave. 



2/yopsocus or Elipsocus sp. (Pack. ) 



Anophthalmus tenuis Horn. (Cope.) Little Wyandotte (Pack.). 



Anophthalmia? eremila Horn. (Copo.) Little Wyandotte (Pack.). 



Fishes : 



Amblyopsis spelceus Tellkf. Wells near Wyandotte Cave. 



Besides these there occur the following twilight species: Qucdius spelceus Horn; Lesteva u. sp. 

 Horn; P/tora sp.; Blepharoptera defessa, Osten Sacken (the Anthomyia of Cope's lists); Caiops 

 n. sp. ?, and an Aleocharid allied to Tachusa (Cope, Amer. Nat., vi., 413). Porcellio sp. blind. 



It will be seen that Wyandotte Cave has about one-third as many species as Mammoth, while 

 theMyriopod (Pseudotremia cavernarum) and thePhalangid (Phalangodes flavescens) are much more 

 numerous in individuals than any terrestrial Arthropods occurring in Mammoth Cave.
