85 males, 98 females (56 ovigerous).—Northeast side, reef flat, 0-1

of rostrum to cervical groove: males, 1.7-6.8 mm.; females without 
egos, 1.6-3.5 mm.; ovigerous females, 2.3-5.0 mm. The length of 
the entire carapace in the midline is difficult to measure accurately, 
because of the membranous posterior part, but it is slightly less than 
twice (1.8-1.9) as long as the anterior portion.
