Like the preceding species, but with the carapace much lower, 

 being scarcely elevated posteriorly in front of the fovea, so that 

 the latter is situated almost on a level with the upper surface of 

 the carapace, the area between the fovea and the eye being almost 

 horizontal. Legs longer ; carapace as long as patella, tibia, and 

 half the protarsus of the 1st, distinctly less than patella and tibia 

 or than tibia and protarsus of 4th.
