of their appearance we refer to the figures. Among the hairs with 
which they are supplied some are plumose, but the branches are so 
diminutive that they could not very well be rendered in the drawing. 
Trochanter (tr) and Femur (f) are found in all legs. The 
trochanter is uncommonly large; however it decreases in length 
from third to the sixth pair of limbs, measuring in the second 
and third pairs 1!/2 times the size of the femur, in the sixth pair 
being somewhat shorter than the femur. 
Patella (p) and Tibia (ti). In the four posterior pairs of limbs 
patella and tibia are separated from each other, but in the pre- 
ceding (the second) pair the structure is different, as only one 
joint (fig. 11, ti) is found. In the third pair the patella is per- 
ceptibly longer than the tibia, but in the succeeding pairs about 
of the same length. 
Metatarsus (m) is 2-jointed in the second pair of limbs, 4- 
jointed in the third pair and undivided in the fourth, fifth and 
sixth pairs. In the third pair (fig. 12a) the two first joints of 
the metatarsus are separated by an articulation which is seen side- 
ways as a very oblique and somewhat curved line; probably this 
link only allows of a very slight movement. Grassi, who con- 
siders it as a suture, reckons these two joints as only one. 
Tarsus s. str. (ta) is 3-jointed in the second and third pairs 
of limbs, 1-jomted in the fourth and fifth, 2-jointed in the sixth. 
Where it is divided, its terminal joint is notably or much longer 
than the others, especially in the third pair of limbs. All the 
legs end in two claws (figg. 12b and 13b) besides being pro- 
vided with a pseudonychium which, as usual, is considerably 
curved. We cannot say precisely how much of the animal's foot 
touches the ground in walking, but we think it is only the ex- 
tremity of it (as in CXelonethi); in this opinion we feel confir- 
med by the fact that none of the joints are provided with spurs. 
Sensory organs. Eyes, as already stated by GRAsslI, are 
altogether wanting. As if in compensation, the head of the ani- 
mal is provided with two couples of sensory organs. Strictly 
speaking, we cannot prove that they are organs of sense, as they 
are much too small to allow of a thorough examination. Seen 
under the microscope, their surface seemed to be closely »dot- 
ted» with fine points; these, no doubt, were very short and thin
