The length of the male is 2£ lines. 



The cephalo-thorax is of a pale yellowish, red-brown colour, 

 divided longitudinally by a central, and two lateral black stripes ; 

 and the oblique indentations between the caput and thorax are 

 also marked by a black line. The fakes are of great strength, 

 long, widely divergent, and armed with strong teeth on their 

 inner sides ; the fang is long, and has a kind of tooth at the 

 middle of its inner side, the outer side at that part being 

 indented. The legs and palpi are of a pale yellowish hue 

 slightly tinged with brown. The abdomen is brownish-black on 

 the upper side, with a broad, pale, yellowish band down the 

 centre, tapering to a point above the spinners, this band has a 

 longitudinal, central, black line, broken into by several, somewhat 

 angular, small spots or markings ; there is also a lateral band, of 

 the same colour as the central one, on each side. The under 

 side is yellowish-brown, with a broad, central, longitudinal, 

 bi-ownish band. 



The palpi of the male are long, and the radial is larger than 

 the cubital joint ; the digital joint is of a somewhat bifid form, 

 one branch being much larger and stronger than the other. 

 The palpal organs consist of a largo globular bulb, with a pointed 

 and somowhat twisted process in front. 



The female is larger than the male and loss vividly and dis- 

 tinctly marked, but in other respects very nearly resembles it, 

 except in the less development of the falces. 



Found, but not abundantly, under stones and among moss and 

 rubbish in woods and damp places at Bloxworth and other
