number of accessory teeth is very large, viz. anteriorly 10 and 

 15 in the movable and immovable finger respectively, while both 

 fino'ers have posteriorly about 30 in addition to the marginal rov^^ 

 The immovable finger has numerous S'pots, especially posteriorly, 

 while the movable finger has only two posteriorly (c/. fig. 32g; and 

 text-fig. 79). 



Coxoe. — The coxse are scarcely different from those of Gli. argen' 

 tinus Thor. {cf. above). 



jjegs. — The hairs are rather short. The legs are long and 

 slender: the tibia of the first pair of legs is almost I'o as long as 

 the tarsits, which is 4-5 as long as deep ; the femii.r of the fourth is 

 2-8 as long as deep, scarcely 1-1 as long as the tibia, and about 1-8 

 lower than the tarsus is long. 



Colour. — The palps and the cephalothorax are dark reddish 

 brown, while the tergal sclerites are pale brown. 



Measurements.— Cephalothorax 1-38 (1*20) ; abdomen 3-0 

 (1'5) mm. 



Palps: trochanter 0-690 (0-460); femur 1-245 (0-552); tibia 

 1-811 (0-621); hand 1-334 (0-805), depth 1-012; finger 1-058 mm. 



Leg I. : femur 0*897 (0-253), trochantin 0-140 (0-276) ; tibia 

 0-736 (0-184); tarsus 0-575 (0-125) mm. 



Leg IV. : femur 1-058 (0-375) ; tibia 1-00 (0-207); tarsus 0-667 



(0-150) mm.

Palfs (text-fig. 80). — The granulation of the palps is perhaps 

 somewhat better marked. The dorsal protuberance of the trochanter 

 is somewhat lower and has a similar, but less characteristic shape, 

 as its tip is not marked out from the rest, but regularly rounded, 

 and as the proximal margin is scarcely obtuse-angled ; the trochanter 

 is as deep as, not deeper than, the femur, which dorsally does not 

 show any trace of terminal concavity. The tibia, the stalk of which 

 appears less slender on account of the almost straight posterior 

 margin, has the antero-dorsal surface very slightly produced. The 

 hand, which is longer, but 1-4 wider, than the tibia, is 1-9 as long 

 as wide, scarcely deeper than wide, and 1*5 as long as the fingers, 

 which are only 1-2 as long as the hand is wide and scarcely gape 

 when closed ; the lateral outlines are a little more distinctly convex 

 than in the male, while the dorsal and ventral ones are less distinctly 

 convex. The number of accessory teeth is much smaller, viz. anteriorly 

 about five in both fingers and posteriorly about twelve, while the 

 number and arrangement of spots is practically as in the male.
