Of "C. brevipes Blackw.", Cambridge has kindly favoured me with 

 a cf ad. — The obtuse spine near the apex, outwards, of the bulbus 

 genitalis in cT, is somewhat curved forwards and outwards, not quite 

 straight, as Westring says. The spine-armature on the legs is in this 

 species very variable. The 4 fore-tibiae have on the under side some- 

 times 4, sometimes 3, sometimes only 2 spines; in the cf the tibiae 

 of the 3 rd pair have on the underside 1, 1 spines in the three full- 

 grown specimens I have seen. In the ?, the same tibiae have usually 

 there only 1 , but occasionally, like the cT, 1 , 1 spines. The length 

 of the cephalothorax varies in both sexes from 2 to 3 millim. — 

 C. paradoxa L. Koch (loc. cit., p. 342, Taf. XIV, figg. 222, 223) 

 must be very nearly allied to, if not identical with, C. brevipes '). 



A species as remarkable as C. brevipes by the form of the pro- 

 cess on the tibial joint of the male's palpi , and which is probably to 

 be met with in many places in this country, though it is not described 

 by Westring, is C. cwrulescens L. Koch (loc. cit., p. 331, Taf. XIII, 

 figg. 213 — 215). The tibial joint of the male's palpus is in this spi- 

 der, on the outer side, produced into a process larger than the joint 

 itself, and which dilates into a large, arched, shining surface , which 

 in front is cloven into three curved points, the innermost of which 

 is longest and rapidly curved outwards. The lamina is very narrow 

 at the base , its inner side longer than the outer. Also the vulva in C. 

 ccerulescens has a most characteristic appearance: the anterior edge of 

 the riraa genitalis is produced backwards over the sexual aperture into 

 a broad arched surface, which is somewhat constricted on both sides of 

 the broad emarginated apex, the corners of which form two shining, 

 backward projecting, somewhat inwards-curved protuberances or short 



1) Dr Koch, to whom I had lately sent a C. brevipes S, still thinks C. 

 paradoxa is a different species: he writes me that C. paradoxa $ has two small 

 strongly curved hooks at the extremity of the bulbus, and that the species is 

 r weit graciler gebaut als G. brevipes".
