extremity; the dorsal surface seems posteriorly to be produced into a rounded 

 tubercle. The femur, which has a short and distinct stalk, is 26 longer than broad, 

 narrower than the trochanter and almost of equal length to but distinctly narrower 

 than the tibia; anteriorlj' it is beyond the stalk very slightly convex and then 

 concave, while it is posteriorly rather abruptly convex and then straight. The 

 tibia, which is about 45 longer than the short and well defined stalk, is 21 longer 

 than broad ; its anterior margin is beyond the fairly deep notch of stalk moderately 

 convex and towards the end slightly concave; the posterior surface has a rather 

 low condylus, merging graduallj' into low basal elevation, bej'ond which the out- 

 line is almost straight and then towards apex distinctly convex. The hand, which 

 is 12 broader than the tibia, is a little shorter than the trochanter, 16 longer than 

 broad and deep and 14 longer than finger; the whole chela is 26 longer than 

 broad; the lateral outlines are beyond the stalk abruptly convex and then mode- 

 rately so; the dorsal and ventral margins are less abruptly convex and then almost 

 straight. 



Coxae (PI. IV, fig. 12 d). — The coxae are minutely, but distinctly granular 

 all over; the first pair are the shorter and scarcely enlarged towards the extremity; 

 the second and the third pair are much longer and distinctly widened out towards 

 the extremity. The fourth pair are remarkable on account of the plate, into which 

 they are prolonged posteriorly, and are as broad as the three preceding pair together 

 and distinctl}' broader than long; the interior margin is very moderately concave 

 or straight, only leaving a narrow space between the two coxae, wdiile the posterior 

 and the exterior margins, the latter behind the articulate cavity, are fairly rounded 

 merging gradually into each other (fig. 12 d). 



Legs (PI. IV, figs. 12e-g; figs. 6 a-b, p. 37). — The legs with the exception of 

 the tarsi are everywhere beset with large more or less squamiform granules in 

 addition to a great number of very small round granules. The hairs of the legs 

 with the exception of those of the tarsi ventrally are more or less distinctly clavate 

 (fig. 12 g); the hairs of the ventral surface of the tarsi are proximally provided with 

 teeth but distally completely simple; the terminal lateral hair is moderately curved, 

 and the tarsal "tactile" of the fourth pair of legs is wanting. The joints of the legs 

 with the exception of the tarsi are provided with distinct stalks; in appearance as 

 well as in structure there is no marked diflerence between the different pair of 

 legs, except a small one in the femurs. The trochantin of the first pair of legs 

 is about one third as long as the whole femur and a little deeper; the femur of 

 the fourth pair of legs is 28 times longer than deep; the tibia of the first pair of 

 legs is 13 shorter than the tarsus, which is 52 longer than deep; that of the 

 fourth pair is scarcely 1-2 shorter than tarsus, which is 28 longer than the femur 

 is deep. 



Colour. — The palps, céphalothorax and tergal sclerites are reddish brown; 

 the rest of the body is lighter or darker yellowish brown with the exception of a 

 median blackish band transversely on the median sternites.
