of the maxillae is wanting behind, where they are covered by the 
first pair of coxae. AA not very well developed lamina is found 
around the manducatory part; the detailed structure of the superior 
surface was not unravelled, About the structure of the palps I 
refer to Ellingsen's description (28, p. 261; and pl. I, fig. 1, 6). 
Coxae and legs (textfig. 1; pl. I, figs 7—10; 28, pl. IV, figs 
7—8). About the structure of the coxae I refer to Ellingsen's 
description and the accompanying fig. 1. 
The legs aré remarkable by the fact that, though in the 
main alike those of Chelifer Geof., they are similar to those of 
the Garypidae Hans., as well 
<Q mas by the well developed ar- 
GEN ticulation of the trochantin in 
the fourth pair of legs. All 
the legs have a uniarticulate 
tarsus, which even in the fourth 
ENS pair of legs is distinctly longer 
than the tibia. The first pair 
has the basal femoral part di- 
stinctly longer than the distal, 
and the articulation has anteriorly a single median tooth, but no 
one behind, thus providing most similarity to that of Chelifer Geof. 
(igs 7—8). In the fourth pair the basal part is rather elongated, 
and the mobility between the two joints is more considerable than

is usually the case, as the distal part is at the base all around 
surrounded by the proximal (fig. 9—10); but as no condylar teeth 
were observed it must be admitted, that the similarity to the usual 
articulation in the fourth pair of legs is greater than that it bears 
to the corresponding articulation in the first pair. 
This genus is in several respects well distinguished from all 
other known false-scorpions, even in a very high degree (cf. With 
29, p. 58). Several of its structures are quite unique within this 
order viz, the well developed ginglymous articulation between the 
Cephalothorax and the abdomen, the remarkable structure of the
