new and rare British Spiders. 207 



cephalothorax being the palest and clearest, and the abdomen 

 the darkest, with a sooty hue. The caput and thorax are about 

 level as far as the thoracic junction, whence the posterior slope 

 is distinct but not very abrupt ; between the occiput, which 

 is rather rounded, and the thoracic junction is a very slight 

 shallow depression. The clypeus is almost vertical, and its 

 height is less than half that of the facial space ; on the fore 

 part of the caput, and along the central line backwards, are a 

 few strong bristly hairs. 



The eyes are of tolerable size, seated on black spots, and 

 occupy the whole width of the fore extremity of the caput ; 

 the interval between those of the hind-central pair is distinctly 

 greater than that between each of them and the hind-lateral 

 eye on its side, being about equal to a diameter ; those 

 of the fore-central pair are contiguous to each other, and each 

 is separated from the fore-lateral on its side by less than its 

 own diameter ; the direction of the lateral pairs is slightly 

 oblique. The four central eyes form a square, whose anterior 

 side is rather shorter than the rest. 



The legs are rather long, slender, 4, 1, 2, 3, and furnished 

 with hairs and a few spine-like bristles. 



The palpi are short and slender ; the radial and cubital joints 

 equal in length ; the former is very slightly produced and 

 rounded at the fore extremity on the upperside, and fur- 

 nished with bristly hairs ; the latter has a single prominent, 

 tapering, slightly sinuous bristle at the fore extremity of its 

 upperside. The digital joint is small, and of a narrow or 

 somewhat oblong-oval form, rather exceeding in length the 

 radial and cubital joints together, and clothed with bristly 

 hairs, especially at the fore extremity. The palpal organs 

 are not very complex ; at their base on the outer side is a 

 strong, bent, somewhat crescent-shaped corneous process, 

 the fore part being strongly emarginate ; and at their extre- 

 mity is a small, straight, sharp, black, thorn-like spine, 

 in contact with some semitransparent membrane. 



The falces are vertical, tolerably long, but rather weak, and 

 divergent. 



The sternum is similar in colour to the abdomen, which last 

 is clothed with strong bristly hairs. 



The female resembles the male in general form and colours, 

 but is larger. The genital process is characteristic but not 

 conspicuously prominent. 



Two males and a female of this spider were found in a 

 swamp near Bloxworth, at the end of June 1879. The male 

 may easily be distinguished from LdnypMa oblivia, Cambr., 

 L. oblita, Cambr., and some other allied and rather obscure
