AnteniKB. — The terminal hair extends perhaps in a slight degree beyond the acute 

 galea, which possesses a few obsolete terminal teeth. 



Palps (PI. XXIX. figs. 8 a-h). — The maxillse are granular laterally and in front, but 

 behind are almost smooth in the middle ; the palps are distinctly granular above with the 

 exception of the hand ; underneath the granulation is less developed and even wanting 

 in the hand, which has its lower surface, like the fingers, smooth all over. All the 

 joints except the fingers are provided with short or very short, more or less distinctly 

 clavate hairs. The trochanter, which has a fairly long and well-defined stalk, is 1'9 as 

 long as wide ; the anterior surface is moderately and regularly convex, while the 

 posterior has the ventral margin just beyond the stalk produced into a fairly long and 

 rounded conical eminence (fig. 8 b), but dorsally it is only slightly produced. The 

 femur, which has a fairly short, well-limited stalk, is scarcely widened out towards the 

 end and is broadest in the middle. It is about o'5 as long as wide; anteriorly beyond 

 the stalk as well as distally it is slightly concave, but a trifle convex or even obtuse- 

 angled between, while posteriorly it is slightly convex basally and then almost straight 

 but for a slightly marked terminal convexity. The tihia, which is distinctly shorter and 

 wider than the femur, has a long well-defined stalk and is almost 2 '5 as long as wide ; 

 anterior outline is distinctly produced in the middle, with the margin almost straight 

 behind the protuberance thus formed, but slightly concave beyond, while the posterior 

 outline beyond the slightly pronounced basal elevation is first straight and then 

 moderately convex. The chela is three times as long as wide ; the hand, which is 

 distinctly narrower than the length of the trochanter, is I'l shorter and 1-5 wider than 

 the tibia, it is 1"5 as long as wide, distinctly wider than deep, and scarcely as long as 

 the fingers, which gape moderately when closed ; the lateral outlines of the hand are 

 distinctly convex. Both fingers have teeth on the margin from near 

 the base to the tip, those of the immovable finger being the better iext-tg. 66. 

 developed ; the immovable finger has anteriorly a single " spot " 

 behind the median tactile hair, and the movable one has either a 

 single spot or two apart from each other in the middle. 



Coxw (PL XXIX. fig. 8 c). — The second and the third pair are 

 scarcely different from the corresponding pairs of the preceding species 

 (cf. p. 243) ; the fourth pair are less slender, have the interior margin 

 longer and better marked, and are almost straight behind, with the 

 postero-exterior corner only slightly produced. 



Jjegs (text-fig. 66). — The proximal joints are granular. The hairs 



of the dorsal surface of the fourth pair of legs are exceedingly short, at Ch.satanas,s\). n.,
