Epistoma (Text-fig. 14). Besides the three teeth mentioned and delineated by 
Trouessart there is often a small tooth more laterally on each side. 
Hypostcnna upon the whole correctly delineated by T. with the exception that 
in reality the maxillary lobes are not fork-shaped but simple. The four usual pairs 
of hypostomatic hairs present. The palpi (PI. II, fig. 2) with five free joints; the 
second (first free) third and fourth of equal length; the second and fourth half as 
wide as long, cylindrical, the third one is thickened and on the ventral side provided 
with a large, rounded, knob-like projection with a longitudinal groove in the top; 
5th and 6th joints together as long as the 4th, the 6th being only half as long as 
the 5th and richly provided with hairs. Hairs of palpi simple, arranged as follows: 
II one ventral; III three dorsal, one exterior, one interior; IV three dorsal, one 
exterior, two interior of which one is feathered; V two ventral, 10 — 12 terminal. 
The mandibles (PI. II, fig. 20). The lower jaw slightly shorter than the upper 
one, with one large, strongly curved terminal tooth and one smaller, sharply pointed, 
median one. It has a long, 
slender, needle-shaped, up- 
wardly curved, pointed calcar 
mandibuli attached with large 
base to its outer side; calcar 
nearly twice as long as the 
chela. The upper jaw is 
straight for s/ 4 of its length, 
provided with one large ter- 
minal tooth and three other 
teeth of which the anterior 
one, situated just in front of 
the sense hair, is extremely 
small, while the other two are 
as large as the terminal one. 
The legs. Legs I (PI. II, fig. 23) long, slender with small, demarcated basifemur 
and basitarsus. Coxa slightly curved, with a small, median, ventral projection; tarsus 
of uniform thickness throughout. 
Legs IL) (PI. II, fig. I) thick, with large, slightly upwardly curved calcar 
femoralis provided with a sharp dorsal edge; processus axillaris small, straight, 
sharply pointed; processus stridularis genualis and tibialis nearly of the same 
hatchet-like shape, with the front angles projecting sharply. The tarsus has a very 
remarkable shape (Text-fig. 13). It is just in front of the demarcation between 
basi- and telotarsus curved downwards and on the internal side provided with an
