TRAP-DOOR SPIDERS. 265 



junctional pit or fovea, whicli is narrow but strong, 

 and gently but equally curved, the convexity of the 

 curve directed forwards ; the thorax next to this 

 fovea is rather gibbous, but not over any great extent 

 of surface ; the other normal indentations are toler- 

 ably strong ; the colour of the cephalothorax is 

 yellow- brown, darkest on the sides of the caput, and 

 along the thoracic indentations, palest on the margins, 

 forming a pale marginal border indistinctly vandyked 

 on the inner edge. The surface is clothed, but not 

 densely, with yellowish-grey adpressed hairs ; there are 

 a few black bristles in a straight transverse line, directed 

 forwards from the lower margin of the clypeus ; also a 

 few more bristles curved and of various lengths before 

 and behind the ocular area, their points meeting over 

 tliis area, and a row of strong, nearly erect ones in a 

 longitudinal central line from the ocular area to the 

 junctional fovea; besides these are a few more, finer 

 and less conspicuous, along the middle both of the 

 caput and thorax ; the colour on either side and in 

 front of the ocular area is orange yellow-brown, and 

 joining with this a broad band of the same runs back- 

 wards from tlie ocular area to the thoracic fovea. 

 The band begins as wide as this area, it then directly 

 enlarges a little, and thence tapers slightly and gra- 

 dually to its termination, forming a truncate wedge, 

 with the margins rather irregular, but on the whole 

 a little curved. This band is not immaculate, there 

 being two dark yellow-brown tapering lines or bars 

 along the greater part of its length ; these bars begin 

 from each outer pair of eyes of the hinder row, and 

 tapering to a fine line, converge to the thoracic fovea, 

 but do not quite meet. It is important to note the
