“ Eyes. Seen from in front, anterior row recurved so that a line tangent to dorsal borders of ALE cuts off about one fifteenth of the diameter of AME. Posterior row wider than anterior row in ratio of about 10 : 9, wider than middle row in ratio of about 17 : 14. Quadrangle of laterals wider than long in ratio of 25 : 18. Total eye space occupies twenty thirty-firsts of the length of the carapace. Ratio of eyes AME : ALE : PME : PLE = 15 : 8 : 2 : 7. AME nearly contiguous to one another and definitely so to ALE. Middle eyes closer to ALE than to PLE in ratio of about 4 : 3. ”
