at the mouth of the fish could scarcely be maintained on a species 
having sight, for if the host did not reniove it, other individuals 
would be apt to. 
I may here allude to another blind Crustacean which I took in 
the Mammoth Cave, and which has been already mentioned in the 
Annals and Magazine of Natural History as a Gammaroid. Mr. 
Cooke and myself descended a hole, and found a short distance 
along a gallery, a clear spring covering, perhaps, an area ten feet 
across. Here Mr. Cooke was so fortunate as to procure the Cæci- 
dotea stygia, while I took the species just mentioned, and which I 
name Stygobromus vitreus. The genus is new and represents in a 
measure the Niphargus of Schiddte found in the caves of Southern 
Europe. It resembles, however, the true Gammarus more closely, 
by characters pointed out at the close of' this article. This genus 
has several species in fresh waters, which are of small size, and 
swim actively, turning on one side or the other. 
Of insects I took four species of beetles, all new to science. Two 
of them of the’ blind carnivorous genus Anophthalmus, and two 
Staphylinidee, known by their very short wing-cases and long, 
xible abdomen. Dr. Geo. H. Horn has kindly determined them 
r me. One of them, the Quedius speleus Horn, is a half-inch in 
length, and has rather small eyes.* It was found not far from 
the mouth of the cave. Dr. Horn furnishes me with the following 
list of Coleoptera from the two caves in question : 
Anophthalmus Tellkampfii Erichs. Mammoth Cave.

These are the only true cave insects at present known in these 
faune. Other species were collected within the mouths of the 
caves, but which cannot be classed with the preceding, as cave
