Detailed measurements of each of the chelate legs, and the number 

 of segments in the carpus, of nine of the above specimens are given 

 below. The first three columns give the number, sex, and length of 

 each specimen, as in the table above ; columns four to nine give the 

 entire length of the leg and the lengths of each of the five distal seg- 

 ments ; and the last column gives the number of segments in the car- 

 pus. For the left carpus this last number is not perfectly definite, as 

 the segmentation becomes irregular and indistinct toward the proximal 

 end.
