fore the abdomen, cephalothorax plainly longer than broad, 
truncate in front, no eyes; the abdomen rather narrow at base, 
broadest toward the middle and broadly rounded at the tip, 
showing above faint transverse marks or sutures; legs rather 
stout, with scattered bristles; mandibles large, chelate, a little 
shorter than cephalothorax, directed slightly downwards; palpi 
a little longer than the mandibles, second joint three times as 
long as broad, third fully twice as long as broad, and with two 
bristles at the tip, fourth about as long as broad, with five or 
six bristles at the tip arranged in a somewhat radiate fashion.

This mite is a somewhat common species, and is found on 
the under side of stones in damp stations; especially may it 
be found under stones on which the egg masses of the cave 
spider, Anthrobia mammouthia Telkpf, occur. I do not know 
whether it attacks these masses in any way, but the association 
„is suggestive of that conclusion. The species is one of the 
smallest of the living forms found in the cavern, being exceeded 
in that particular only by the following one. It has only 
occurred in collections from near the bottom of the Bottomless 
Pit and in Blacksnake Avenue, in which Richardson’s Spring 
is located. More than two-thirds of all the species known from 
Mammoth Cave came from near this station or at it.

“Length .6 mm. Pale yellowish, legs paler. Body oblong, 
rounded in front and behind ; cephalothorax as broad as long, 
a shining eye on each side distinct; abdomen globose, above a 
silvery T mark, dorsum with a few hairs above, longer ones at 
the tip, and small ones each side of anal opening; leg I very 
long and slender, femur I as long as body, tibia shorter, meta- 
tarsus much longer than body, tarsus shorter, apparently not 
divided, femur IV thickened; the mandibles form a rather 
elongate cone; palpi plainly longer, joints two and three and 
subequal, smallest at base and rather clavate in form, fourth 
smaller and shorter.
