 or iv., as long as protarsus iv. ; fovea deep, right transverse. 



Eyes of the anterior row procurved, the anterior edges of 

 the medians being on a level with the centre of the laterals, 

 nearly evenly spaced, the medians being much the smaller, 

 separated from each other by about two diameters ; posterior 

 medians much smaller than the anterior medians, close to 

 posterior laterals, which are smaller than the anterior laterals 

 and separated from them by less than the long diameter of the 

 latter. 



Fang-groove with twelve teeth (4-|- 5 + 1 + 1 + 1) on inner
