Pedipalpi, Ricinulei, and Opiliones. 25 



Sexual differences are found in the above-named protu- 

 berance on the cephalothorax and in the three anterior pairs 

 of legs. First legs are scarcely or distinctly thicker in the male 

 (fig. 2 d), than in the female (fig. 2 e), but at least the shape of 

 the metatarsus is rather different in the two sexes ; in the female 

 the metatarsus is moderately slender, with the same thickness 

 in its whole length, and its lower, inner margin is feebly convex; 

 in the male the metatarsus is thicker, increases a little in 

 thickness from the base to a little from the end, and the distal 

 two-thirds of its inner margin is much more convex than in 

 the female. Second legs are somewhat varying, as the}- may 

 be similar in both sexes or a little stouter in the male. 



The copulatory organs (fig. 2 g) on third pair of legs on the 

 whole similar to those in C. W ester mannii Guer. and C. Sjo- 

 stedtii Hans. & Sor. ; of course the movable process of first tar- 

 sal joint has a shape of its own and affords as usual excellent 

 specific characters. It may be mention(^d that the metatarsus 

 from in front (fig. 2 g, 6) is somewhat more than twice as long- 

 as thick; its movable process has the most distal slender part 

 curved ver\' considerably backwards. First tarsal joint {d) 

 is uncommonly long, being, seen from below, only somewhat 

 shorter than second and very much longer than the third, 

 which is somewhat shorter than the fourth. The second tarsal 

 joint {e) has the distal triangular process {e^) of the front wall 

 rather small, while the lamina cyathiformis {e"), is high, and 

 consequently the upper end of its wall is more than twice 

 as far from the distal lower end of the joint than is the case 

 with the tip of the process from the front wall. The movable 

 process {d^ — d~) of first joint has the distal segment about twice 

 as long as the proximal; the distal segment seen from the 

 outer side (fig. 2 h) is rather narrow, the proximal process from 

 its front margin is situated considerably before the middle^ 

 and is somewhat short, oblong-triangular, and very acute;
