FOSSIL SCORPION. 407 
in July, 1834, in a stone-quarry, on the outcrop 
of the Coal measures, near a spot where coal has 
been wrought since the sixteenth century. In 
the same quarry were found four erect trunks of 
trees, and numerous vegetable remains, of the 
same species that occur in the great Coal forma- 
tion of England. 
A series of drawings of this Scorpion was sub- 
mitted to a select committee at the meeting of 
Naturalists and Physicians of Germany, in Stut- 
gard, 1834 ; and from their report the subjoined 
particulars are taken. All our Figures, (PI. 46.) 
are copied from those attached to this Report, 
in the Transactions of the Museum of Bohemia, 
April, 1835.* 
* This fossil Scorpion differs from existing species, less in general 
structure than in the position of the eyes. In the latter respect, 
it approaches nearest to the genus Androctonus, which, like it, 
has twelve eyes, but differently disposed from those of the fossil 
species. From the nearly circular arrangement of these organs 
in the latter animal, it has been ranged under a new genus, Cy- 
clophthalmus . 
The sockets of all these twelve eyes are perfectly preserved, 
(PI. 46'. fig. 3.) One of the small eyes, and the left large eye, 
still retain their form, with the cornea preserved in a wrinkled 
state, and their interior filled with earth. 
The jaws also are very distinct, but in a reversed position. (PI. 
46' fig. 2. a.) Both these jaws have three projecting teeth, and 
one of them (PI. 46', Figs. 4. 5.) exhibits, when magnified, the 
hairs with which its horny integument was covered. 
The rings of the thorax, (apparently eight) and of the tail, are 
too much dislocated for their number to be accurately distin- 
guished, but they differ from all known species. The view of the
