L. Koch, but may readily be distinguished by its smaller size (the 

 cephalothorax is but 1 '/ 2 millim. long) and the different form of the 

 tibial joint's process in the male. "This projection in C. trivialis is 

 spatular-shaped and concave inside, while in C. diveraa it is pointed" 

 (Cambr., loc. cit.). — The tibiae of the 3 rd pair have one spine in the 

 midst of the under side; but beside that there is, at least sometimes, 

 a finer spine nearer the base. The area of the vulva is dark at the 

 sides, with the posterior edge produced into an obtuse angle. 



Under the name of C. pallens Blackw. (see Spid. of Gr. Brit., 

 I, p. 130, PI. VIII, fig. 82) I have received from Cambridge a 3 and 

 ? of another, still smaller species. Its cephalothorax is but 1 mil- 

 lim. long, yellowish brown with a very fine black border, the ab- 

 domen without any design, darker above, brownish, on the sides and 

 underneath yellowish or reddish. The mandibles are blackish or 

 rusty brown, the maxillae and labium dark, the sternum and legs 

 pale yellowish. The posterior centre eyes are more remote from 

 each other than from the lateral eyes. The male's palpus-clava is 

 blackish brown, the very short tibial joint is at its apex drawn out 

 into a very short, lamellar process rounded at the extremity, and 

 lying close along the lamina. (In C. pallens [Hahn] L. Koch the 

 process is tolerably long, pointed, and directed outwards and forwards). 

 The tibiae of both pairs of fore legs have on the under side 2, 2 

 spines, their metatarsi 2. On the under side of the tibiae of the 

 3" 1 pair I can see on my specimens only one spine. For this species 

 I propose the name C. mimdula. — Blackwall's description of the 

 process on the tibial joint of his C. pallens seems however to indicate, 

 that he had the real C. pallens (C. diversa Cambr.), and not 0. mi- 

 nutula before him. 



C. pallens Hentz (Descr. and fig. of the Aran, of the Un. States, 

 in Bost. Journ. of Nat. Hist., V, p. 449, PI. XXIII, fig. 13) is a 

 fourth species with this name. It is cited by L. Koch under C. 

 excepta L. Koch (loc. cit. , p. 300, Taf XII, fig. 191).
