Specimens in the Museum: 
o (8 juv.), 2 9 (1 juv.) Japan (types and co-types of de Haan). 
1) Judging from Hilgendorf’s figure of the cheliped it seems to me doubtfui whether his 
specimens are really referable to this species, as the mobile finger is transversaly striated, not 
tuberculated. « 
2) These specimens have been later (1902) referred by de Man partly to the subspec. indica, 
partly to Sesarma livida.
