232 General Notes. { March, 
Among insects a single cricket ( Ceuthophilus maculatus Harris) 
occurred not far from the entrance, and a beetle with eyes (Cryp- 
tophagus sp. indet.) which had probably been carried in by the 
men at work on the stairways and walks; also two small flies, 
while the true cavern fly which we have found in caves in Ken- 
tucky, Indiana and Utah was common; we refer to Blepharoptera 
defessa Ostensacken. Of Thysanura, two species occurred; a 
pale whitish-red Smythurus, with pale reddish eyes, and faded 
whitish specimens of Zomocerus plumbeus (Linn.) of the same 
color and appearance as those collected by us in the, Carter 
- caves, Kentucky. The body was nearly white, the antennz darker, 
the eyes black. 
e Luray caves, in Luray valley, were less populous in the 
‘parts fitted up for visitors, owing undoubtedly to the recent walks 
and stairways built by the proprietors. Spiders were numerous, 
however, all belonging to one species, Linyphia weyert Emerton; 
they differed only from the type specimens in having rather 
smaller eyes. Spirostrephon copei was less common than in the 
Newmarket cave. The fauna of these caves was essentially like 
that of Weyer’s cave. The writer would add that he is collect- — 
ing materials and intends soon to publish a monographic account 
of the cavé fauna of the United States, in the reports of the Ken- 
tucky Geological Survey, under whose auspices most of the 
material has been collected ; and would be grateful for the loan of 
specimens.—A. S. Packard, Fr. 
A Rare Fisu 1n Itttnois.—A specimen of Chologaster in the 
collection of the Illinois State Laboratory of Natural History, 
was obtained by Mr. F. S. Earle, of Cobden, Illinois, in August, 
1878, from a spring at the foot of a bluff, in Western Union 
county, in the southern part of Illinois. . 
The description of Chologaster cornutus Agassiz, was based on 
three specimens from South Carolina, and that of C. agassisu 
Putnam, on one from Tennessee ;—these four specimens being 
apparently all that were known at the time of the publication of 
Mr. F. W. Putnam’s synopsis of Heteropygii, in 1871. 
The Illinois specimen differs materially from the others, but as 
it is intermediate in several particulars between the two described 
species, and as specific descriptions drawn from so small a num- 
ber of individuals must have a very uncertain value, I will give 
an account of this specimen prepared by comparison with the 
descriptions of Putnam’s synopsis, without attempting to decide 
whether it belongs to a new species or whether it unites the two 
previously proposed. Head in body, without tail, 3% times; the 
eye is above and well behind maxillaries and is contained about 
six times in head; the pectoral fin reaches half way to the dorsal; 
the color is precisely as in cornutus, except that the middle stripe, 
dark on the head, is decidedly paler than the ground color on the 
hody, the change being abrupt at the opercular margin. The
