marked with one or two black armuli, and an oblique black line 

 on tbe outer side of the femoral and genual joints. 



The palpi are dark red-brown. The radial joint is shorter 

 and smaller than the cubital, and has a small, pointed, prominent 

 apophysis at its extromity on the outer side. Tho digital joint 

 is largo, and oval in form ; the palpal organs aro large and 

 prominent, especially at their base, and at their outer extremity 

 is a circularly curved black spine. 



The falcos are small, rather directed backwards, and of a 

 yellow-red colour. 



The abdomen is short, broad, flattened, and truncated in front, 

 fitting closely over the base of the cephalo-thorax. The upper 

 surface is of a coriaceous nature, thickly marked with minute 

 punctures ; it is of a deep chocolate red-brown colour, thinly 

 clothed with hairs. A broadish, longitudinal, central band, of 

 a deeper hue, enlarging and somewhat dontated or bifid towards 

 its hinder part, is sometimes discernible. 



The female is very different in colours and markings from the 

 male, and at first it is not easy to recognise it as the female sex 

 of the male above described. The cephalo-thorax is thickly 

 clothed with yellowish-white pubescence, and the caput is marked 

 with an indistinct, longitudinal and transverse dark lines. The legs 

 are very short, of a pale yellowish- white, with the black lines and 

 annuli more numerous and more distinct than in the male. The 

 abdomen is red-brown, clothed with whitish pubescence ; tho fore 

 part of the upper side has a longitudinal, central, dark brown 

 band, followed by a paler central portion marked with several 

 small angular bars. The humeral and cubital joints of the palpi 

 are black, and the radial and digital joints yellow. 



This sex is of even a more dumpy form than the male, owing 

 to the larger size of the abdomon in comparison with the 

 cephalo-thorax. 



Ballus depressus is by no means a rare spider on underwood, 

 and on the lowor boughs of oak trees in woods, at Bloxworth, 

 in the summer months ; and has occurred also in other parts of
