A specimen of the genus Zombis Sim. has shown 
in all respects great accordance with Galeodes. 
In Rhax annulata? the transverse area on all 
3 pairs of legs is very weakly developed, having but 
on the hindmost pair of legs some irregular furrows, 
the smooth area at the basis narrow, not much raised, 
the roof of metatarsus very short. The movement very 
well developed in the vertical, slightly in the horizontal 
plane. 
In Gluvia caucasica? (see above) the articulation 
is simple, without transverse area and discernible roof, 
appearing, however, very movable in both planes. 
In Cleobis Cubce Luc. the smooth area makes an 
intermediate link between the form in Solpuga and 
Galeodes; the transverse area is exceedingly slightly 
developed on the 2d and 8d pair of legs, more strongly 
on the 4th, seeming, however, all over to be lacking fur- 
rows; the roof short.” The movement is well developed 
in both planes, the foot remarkably capable of bending 
upwards. 
I have no doubt that the differences stated here 
must be of some importance to the movement of the 
foot, and thereby to the nature of the walk of the 
animals, in that way being of systematic importance. 
The examination is in the easiest way executed with a 
strong magnifying-glass on as large specimens as possible. 
G. Rostrum. 
This most remarkable organ represents a consider- 
able difference in form in the genera known to me. It 
is not my intention to give a closer anatomical representa- 
tion of the structure of the rostrum; it suffices to give 
names to the parts, necessary to illustrate my object. 
The rostrum tapers in front into an unpaired, dorsally
