方法在显微镜目镜下测量甲壳的长度，从其最高点到脊柱底部(Uéno1934)。眼球单位到标准长度单位的换算是基于同一显微镜获得的已知长度的测量。这些材料是用福尔马林保存的。同时，在一些个体上，还测量了爪子从底部到尖端的长度，并测量了后腹的牙齿数量。
MethodThe length of the carapace has been measured from its highest point to the base of the spine (UÉNO 1934) on the scale of the ocular of a microscope. The conversion of the ocular units to the standard length unit was based on the measurements of known lengths obtained by the same rnicroscope. The material was preserved by formalin. On some of the individuals at the same time, the length of the claw from its base to its tip was also measured, and the number of the teeth on the postabdomen was me< ked.
