Lcg/i pale orange-yellow, apex of each joint slightly tinged 

 with dusky brown. Femora of all four pairs without any 

 spines: genual joints with a single fine short spine at apex. 

 Tibias i. and ii. with three spines towards apex — one dorsal, 

 two lateral, and a dorsal one towards the base ; iii. and iv. 

 with two dorsal ones only. 



Ahflovien dull black ; dorsal area towards spinners paler, 

 bearing in the female a very indistinct, pale, scalloped band 

 down the dorsal area, becoming obsolete before the spinners. 



Palpi. — Humeral joint yellow, slender ; cubital convex, 

 M ith a single short bristle in front at the apex. Radial joint 

 broader, short, convex, furnished with a few stout bristles and 

 hairs directed forwards. Digital joint large. Palpal organs 

 furnished at apex with a stout spiraliform black spine having 

 witliin its circumference a short, curved, black spur ; also a 

 semitransparent plumule. The falciform process, on outer 

 side near the base, exhibits near its apex a stout black spine, 

 composed of three closely applied se])arate spines. This 

 spine is best seen from in front, but was very apparent in 

 some specimens wdiich had become accidentally dried. The 

 apex of the black spine will be seen directed upwards and 

 outwards from the outer side of the organs near the base, and 

 will be quite sufficiently evident for identifying the spider. 



Epigyne transverse-oval, convex, ])resenliiig a short, cen- 

 tral, tongue-like prominence, flanked on either side by a deep 

 concavity, its margin slightly sinuous. From the centre of 

 the posterior margin extends a small dilated process, curving 

 slightly upwards from beneath the apex of the tongue-like 

 process. 



Three males and two females of this small but very distinct 

 little species were taken by myself in jSewtown Moss, near 

 Pcm-ith, in Ajiril 1893. Spiders of all kinds were very 

 scarce, this species being the only one adult. 



This small spider most resembles 13. jxigrinusj Bl., and is 

 also very similar to B. parvulus ; the much smaller size, 

 however, will enable it to be distinguished from the first, 

 while the difference in the form of the falciform jtroccss of 

 the palpal organs will prevent the males being confused with 

 either of them or with gracilisj Bl. These four spiders differ 

 from others of the genus in possessing a stout circular spine 

 surrounding the apex of the organs. For figures and descrip- 

 tions oi B. par villus and B. niqrinus^ see 'Ann. vS: Mag. Xat. 

 Hist.' ser. 6, vol. x., Nov. 1892. 



Both sexes of sctiger mag, hoiccver^ he most easily recog- 

 nized hy the total absence of spines on the femora of all four 

 pair of legs.
