Specimens were examined by histological method to determine the cycle of the gonad development of this nemertean. The results showed that: The sex ratio (female: male) was about 1: 1. The sizes of mature males and females were not significantly different; females are rosy in colour and males are white, largely owing to the metamerically arranged gonads. Gonads, which were not detected in samples of autumn months, arose in December, but sexes were indistinguishable until middle January.
