Adult male length 5^ lines, length of cephalothorax 

 3 lines, breadth 2J. 



The cephalothorax is of a short, broad-oval form, 

 its length being only half a line greater than its 

 breadth ; it is flattened-convex above, and depressed 

 near the margins, the caput (when looked at in profile) 

 scarcely rising above the level of the thorax. At the 

 junction of the caput and thoracic segments is a deep, 

 circularly-curved indentation, or fovea, the curve of 

 which is directed backwards ; the extremities of this 

 indentation are continued obliquely forwards on either 

 side, forming the normal ones which indicate the junc- 

 tion of the caput and thorax. Rather more than one- 

 third of the distance between the above curved inden- 

 tation and the fore margin of the caput is a very 

 perceptible and deep but narrow, slightly curved, 

 transverse indentation which divides the caput into
