Remarks. The four specimens agree with the description and illustrations of Baba (1969). This species is similar to S. acroporae Baba, 1972 . Two obvious differences between these two species are: S. edwardsii has no spine on second abdominal segment whereas S. acroporae has two; and the basal article of antennule of the former has five spines whereas the latter has four.
