slightest degree produced posteriorly. The femur, which has a short, hut vcrj' 

 well defined stalk, is twice as long as broad and as long as, but distinctly narrower 

 than the tibia ; the anterior surface has just beyond stalk a short and rather abrupt 

 convexity and is then moderately concave; the posterior surface is beyond stalk 

 very abruptly convex and then moderately convex; the joint is dorsally even better 

 raised than posteriorly. The tibia, which is about 3 times longer than the thick 

 and well defined stalk, is 17 longer than broad; the outline is anteriorly beyond 

 the deep notch almost circular; the posterior margin is beyond the prominent 

 condylus and the basal elevation, which is fairly well marked proximally, but 

 scarcely distinguished distally, distinctly convex. The hand, which is distinctly 

 longer than the tibia and 13 broader, is much broader than the trochanter is long, 

 almost 1'4 broader than deep, 16 longer than broad and 1-4 longer than fingers, 

 which are much shorter than hand is high ; the whole chela is about 28 longer 

 than broad. The fingers bear, in addition to the rather low and only partly 

 pointed marginal teeth, a few accessory ones both anteriorly and posteriorly on both 

 fingers; the anterior and posterior outlines of the hand are moderately convex, but 

 the ventral and especially the dorsal margin are just beyond stalk very abruptly 

 convex and then moderately so. 



Coxae. — The fourth pair are enlarged towards the extremity and almost 

 square; the posterio-interior corner is obtuse-angled, but not very distinctlj' so, and 

 the interior margin is only a little shorter than the straight posterior one ; the coxa 

 is about lo longer than broad. 



Legs. — The hairs are rather slender, pointed and simple or only with a 

 few distal teeth; the trochantin of the first pair at least with a distinctly longer 

 and more slender one ventrally; dorsal "tactile" hair of the fourth pair of legs 

 seems to be wanting; the terminal lateral hairs are moderately curved and simple. 

 The trochantin of the first pair of legs is short, not so deep as tlie femur proper 

 towards the tip, and with the articulate cavity rather poorly developed, having the 

 ventral and posterior articulate head only a trille more distally than the dorsal ; 

 the femur of the fourth pair of legs is about twice as long as deep. The tarsus of 

 the first pair of legs is only a trifle shorter than the tibia and 34 longer than 

 deep; the tarsus of the fourth pair is only 12 longer than the femur is deep. The 

 claws are simple. 



Colour. — The maxillae and the trochanter of the palps are yellowish, the 

 femur and the tibia are light and the chela dark reddish brown. The head and 

 first thoracic tergite are reddish brown, and the tip of the abdomen is dark 

 brown, with the anterior pale brown tergites separated by distinct yellow articulate 

 membranes. 



Measurements. — Céphalothorax 0772 (0-588); abdomen 1-876 (0784) mm. 



Palps: trochanter 0-336 (0-205); femur 0-560 (0-280); tibia 0-5()0 (0-310); hand 

 0-644 (0-392), depth 0-532; finger 0448 mm.
