6o ON SOME RARE ARACHNIDS 



yellowish brown spots. The first two of these are single, but 

 the posterior ones are multiple, the spots being arranged in 

 oblique rows, running downwards and outwards, and forming 

 with their fellows of the opposite side very indistinct and 

 imperfect chevron marks. In the centre of the cephalothorax, 

 between the two posterior eyes, is a small oval depression. 

 The three posterior pairs of legs are fairly slender, but the 

 anterior pair is much modified. In each leg the femur, 

 patella, and tibia are very much thickened, and being nearly 

 black in hue contrast strongly with the metatarsus and tarsus, 

 which are slender and of a pale yellowish brown colour. Each 

 tibia and metatarsus bears beneath two parallel rows of strong 

 spines, of which three pairs are carried by the tibia, and two 

 by the metatarsus. The vulva is quite characteristic, and on 

 the plate I indicate the natural size of the animal, which is 

 about 4 mm. in length. The Rev. O. Pickard-Cambridge and 

 Professor Kulczynski, to each of whom I have submitted this 

 spider, both concur as to its identity. The vulva somewhat 

 resembles that figured by Bosenberg^ but it is not easy to 

 believe that his figures of the spider from above, and of one 

 anterior leg, refer to the same species.

Three males of this small species were captured in April 

 and May at Huddersfield by Mr. Falconer. He had previously 

 discovered the female, which was described and figured 

 by Mr. Cambridge.| These males are thus new to science. 

 They resemble the female in size, colour, and facies, and there 

 appear to be no marked secondary sexual characters. The 

 cephalothorax is rounded, and bears no ocular eminence or 

 occipital gibbosity. Postocular depressions or striae are not 

 present. The relations of the eyes are similar in the two 

 sexes. The palpi, however, are quite characteristic, this being 

 specially noticeable when they are viewed from below. The
