dorsal and ventral ones are less distinctly so. The number of accessory teeth is some- 

 what variable, but is generally large as shown in figs. 31 a-b, viz. eight and six 

 anteriorly, and twelve and fifteen posteriorly, in the immovable and movable finger 

 respectively. The movable finger has anteriorly no " spots " and posteriorly only a 

 few, while the number in the immovable finger varies, but is often more or less 

 similar to that represented in the figures (figs. 31 a-h). 



Coxce (text-fig. 74, p. 291). — The fourth pair are somewhat triangular, distinctly 

 widened out towards the extremity, and have the hinder margin much longer than 

 the inner and not very well separated from it. 



Legs (PI. XXXI. figs. 31 c-d). — The hairs are moderately long. The legs are 

 long and slender ; the tibia of the first pair of legs is 1-2 as long as the tarsus, which 

 is five times as long as deep ; the femur of the fourth pair of legs is 2*9 as long as 

 deep, scarcely longer than the tibia and about half as deep as the tarsus is long. 



Colour. — The palps and the head are dark reddish brown; the tergal sclerites 

 blackish brown.

XXXI. figs. 31 e-f; text-fig. 77). — The dorsal protuberance of the 

 trochanter is much lower and more rounded (fig. 77j ; the femur is less 

 abruptly convex as well posteriorly as dorsally, and has no terminal con- 

 cavity dorsally. The tibia, which is 2-2 as long as wide, is anteriorly 

 moderately convex, and posteriorly only slightly so terminally; the 

 ventral outline is moderately convex and the dorsal is very slightly so, 

 and has the antero-dorsal surface scarcely produced. The chela, 

 which is three times as long as wide, is only 1-1 broader than the 

 trochanter is long ; the hand is almost 1-8 as long as wide, a trifie 

 wider than deep, and 1-4 as long as the fingers, which are about 1-3 

 longer than the hand is either wide or deep, and scarcely gape when 

 closed ; the lateral, as well as the dorsal and ventral margins of the 

 hand, are less distinctly convex. The numbers of accessory teeth and 

 of spots are generally somewhat smaller (figs. 31 e-f). 



Cowce (text-fig. 75, p. 291). — The fourth pair have a quite diff'erent 



shape, being much broader and scarcely widened out towards the 

 extremity, with the inner margin much longer than the hinder and of a somewhat 

 trapezoidal appearance.
