inferences as to the character of the dorsal and ventral sides can be drawn 
from its present position. 
Appendages. The appendages present the greatest difficulties to a 
correct interpretation on account of their unfavorable preservation and 
small size. We find, accordingly, wide differences in the views held by 
the authors concerning them. 
One of the two chelicerae has been pushed forward and is seen in 
front of the carapace. Its distal portion is preserved only as an impres- 
sion and but a portion of one finger 1s noticeable. The proximal portion of 
the powerful second joint is preserved as a flattened tubular body, dis- 
tinctly broken off in front. Fritsch has interpreted this part as the man- 
ducatory lamella of the coxa (Kauglied), and states that it shows a short 
curved claw at the anterior margin. Inspection of the specimen, however, 
shows readily that the hand of the chelicera is the direct continuation of this 
proximal part, and that the latter lies upon the coxa of the pedipalp. The 
short claws are not visible in the specimen and Fritsch’s representation is 
apparently due to shadows produced by irregular depressions between the 
lost anterior and the preserved posterior portions of the chelicera. 
The greatest difficulty is presented by the legs, since these appen- 
dages are piled together in one place and badly torn. They have therefore 
been very differently interpreted and caused much of the controversy 
about this scorpion The second joint of the left pedipalp (trochanter) 
is seen as an impression at the left of the base of the chelicera, which it 
underlies The third joint (humerus or femur) stands, as in other scor- 
pions, at right angles to the trochanter and partly underlies the left side 
of the carapace. It is broader and longer than represented by both Whit- 
field and Fritsch. It is partly broken off where one of the walking legs 
underlies it. Whitheld [op. cat. pl. 20, fig. 1, 3] represents this joint as 
directly connected with the chela or hand of a pedipalp seen in the 
specimen, by a short fourth joint (brachium or tibia), but Fritsch sees 
in this connecting broken film “a triangular sternum on which one dis- 
? 
cerns no further details,’’ and ‘two oval opercular plates,’ adding that
