which has a short well-defined stalk (beyond which it is distinctly attenuated 

 towards the end), is 2*2 as long as wide ; the anterior outline is slightly convex 

 proximally and terminally a trifle concave, while the posterior is rather 

 abruptly convex beyond the stalk and then almost straight. The tibia, which 

 has a short and very well-defined stalk, is shorter but somewhat wider than 

 the femur, and is 2'1 as long as wide ; anteriorly it is moderately convex 

 proximally and a trifle concave terminally, while the posterior outline is, 

 beyond the large and prominent condylus and rather insignificant basal 

 elevation (separated from each other by a deep incision), almost straight and 

 then slightly convex. The chela, which is 3*4 as long as wide, is almost 1'2 

 narrower than the trochanter is long. The hand, which is 1'2 as long as well 

 as wide as the tibia, is almost 2'2 as long as wide, distinctly 1'2 wider than 

 deep and 1"6 as long as the movable finger, which is distinctly longer than 

 the immovable and 1'3 as long as hand is wide, but 1*6 as long as hand is 

 deep ; the hand is very suddenly enlarged beyond the stalk, as the outlines, 

 especially the posterior, are almost perpendicular upon it, and then almost 

 straight. The margins of the fingers are peculiarly shaped ; the immovable 

 finger has the ventral margin concave basally, convex in the middle, and then 

 a little concave again {cf. figs. 4 & 5), while the movable is convex basally and 

 then concave towards the terminal fourth, where the fingers touch each other 

 when closed ; as the convexities and the concavities of the two fingers are 

 not equally well marked and do not fit completely into each other, the fingers 

 gape slightly in basal third and fairly distinctly beyond the middle, as seen in 

 the figures ; besides which the movable finger, just where the margin is 

 convex posteriorly, has a swelling, corresponding to an anterior bend, while 

 the immovable has a swelling anteriorly and a bend posteriorly, where the 

 margin is convex but less marked. The fingers cross each other in a slight 

 degree, so that the margin of the immovable finger is terminally covered by 

 the movable, when seen from behind. The fingers bear anteriorly towards 

 the end about three accessor!/ teeth, while the immovable finger has posteriorly 

 twelve and the movable eight. The number of sjyofs is anteriorly five and 

 three on the immovable and movable fingers respectively, while both fingers 

 bear three posteriorly, arranged as shown in figs. 4 & 5. 



Coxa'. — The second and third pairs are very elongated and distinctly 

 widened out towards the extremity, especially the former, which rather 

 suddenly narrows towards the base and has inner margin much shorter 

 than that of the third pair. The fourth pair are almost trapezoidal, not 

 at all widened out towards the end, and have the inner and hinder 

 margins, of which the former is somewhat longer, gradually merging into 

 each other. 



Legs. — The proximal joints are slightly granular. The hairs are dorsally 

 short and slightly clavate, and ventrally longer and more simple ; a tarsal 

 " tactile " hair seems to be present about in the middle. The legs are rather
