 transverse, a little narrower than the tubercle ; tubercle large, 

 wide, projecting slightly beyond the anterior border, which 

 is thus convex at tiiis spot ; distance between front edge of

 Eyes of front row about straight, equidistant, median the 

 largest and separated by a space which is less than their 

 diameter; posterior lateral a little smaller than anterior 

 lateral ; length of carapace a little less than that of patella 

 and tibia of fourth leg, width equal to length of protarsus and
