E x o p o d i t e:The proportion between the length of this branch and that of the protopodite is about 10: proportion between the length of the first joint and the total length of the eightfollowing joints is about 10 : 4. The proportion between the length of the longest nata-tory bristles and that of this branch is about 14 : 10. As far as I could observe thefirst joint is quite bare.
