the 3 of which are rather long. The group is placed 
near the posterior margin, in a little distance from the 
median line. 
3d sternite on each half with a group of 3 com- 
paratively long, slightly oblique longitudinal fissures near 
the posterior margin in a little distance from the 
median line. 
4th sternite on each side with c. 3 middle-long 
oblique fissures dispersed between the median line and 
the lateral margin. 
5th sternite on each half with e. 3 fissures along 
the posterior margin, 3 along the lateral margin and 1 
further inwards on the sternite, slightly more removed 
from the lateral margin than from the anterior and the 
posterior margin. 
6th, 7th, 8th and 9th sternite almost as the 
oth, on each half, howewer, with c. 5 fissures of very 
different length along the posterior margin, finally with 
1 or 2 fissures rather removed from the posterior 
margin. 
LOth, ith and, 12th’ sternite. almost as the 
preceding, the number of the fissures is, however, 
reduced in the same way as on the corresponding 
tergite. 
The difference between the distribution of the lyri- 
form organs in this order and in the Scorpions is 
great and most interesting. In Phrynichus but few 
organs are found on the legs, as femur, patella, tibia 
(3—5th joint) and tarsus are perfectly devoid of organs 
(the 3d (and 5th) joint of the Ist pair of legs excepted); but 
in return they are spread as single fissures nearly on the 
whole body and appear also on the mandibles. The 
dilatation for the nerve is situated in the not too short
