E x o p o d i t e: The proportion between thelength of this branch and that of the protopodite is about 14 : 30. The proportion betweenthe length of the first joint and the total length of the eight following joints is about 2:1. Tlie. I-i^. CXVI. - Omchocaa ohlonga (C. Claus). - 1. Shril fion, side. J: 6 X. 2.
