besides a single tactile iiair near the inner margin and nearer 

 to the middle than to the base (fig. 1 b, 1) ; the iramoval)le 

 finger possesses on the outer surface three tactile hairs near 

 the base and two more distally (fig. 1 c, 4-8) ; the dorsal 

 surface with two distal hairs (fig. 1 b-c, 2-3), and the inner 

 without any. The movable finger has four tactile hairs on 

 the outer surface (fig. 1 c). Outside, near the base of the 

 fingers, we find a peculiar organ, shaped like a compressed 

 horseshoe (fig. 1 c, h) and with a clear spot inside. Four 

 similar ones are found interiorly near the upper margin 

 at the base of the finger, the one placed above the other, 

 each consisting of a low elevation with almost oval outline, 

 and provided with a round clear spot at the top in the 

 middle ; each of the spots seems to possess a median dot 

 (comp. 15, p. 201). 



The trochanter, which is twice as long as bi'oad, is dis- 

 tinctly stalked and gradually widened out distally ; the 

 inner side is, with the exception of a low basal concavity, 

 regularly convex from the base to the tip ; the outer side is 

 slightly curved inwards. ll\\e femur, which is 3'5 times longer 

 than broad, is provided with a distinct but short stalk; theinte- 

 rior side is slightly and almost regularly convex from the base 

 to the tip ; the outer side has, after the shallow notch which 

 marks off the stalk, a low elevation ; beyond this there is first 

 a low concavity and then a moderate convexity. The tibia, 

 which is slightly shorter and broader than the femur, is 

 distinctly stalked and gradually enlarged distally ; the inner 

 side, beyond the concavity which marks off the stalk and the 

 following low elevation, is slightly convex or, uiore correctly, 

 shaped as a very open obtuse angle ; the outer side is almost 

 straight both before and beyond the scarcely visible elevation 

 of the stalk and at last slightly convex. The hand, which is 

 a little shorter than the tibia, but uearly twice as broad as 

 the femur, is higher than broad and shorter than the fingers. 

 The convexities of the superior and especially of the interior 

 surfaces are much more marked than those of the inferior 

 and exterior ones. Both fingers bear obtuse, squarely 

 truncate, densely placed teeth ; the tip of the immovable 

 finger is much more hooked than that of the movable one. 



Cox(B (PI. X. fig. 1 a). — The coxae are all placed on the 

 same level, but on a lower level than the maxilhe. The 

 first pair is almost as broad as long and scarcely enlarged 

 towards the exti'emities ; the second pair is of almost equal 

 breadth, but distinctly enlarged distally ; the third pair is 

 so much enlarged distally that it becomes almost triangular, 

 but much less marked than the corresponding pair in
