The leucopoietic organ of the crab, Sesarma intermedia (DEHAAN), was studied by histological methods after the amputation of both eyestalks. On the first or second day after the operation, the leucopoietic organ of an eyestalkless crab filled up with many matured haemocytoblasts which had basophile granules in the cytoplasm, and the organ is believed to release a great number of haemocytes into the blood by the first or second day. On the third annd fourth day of eyestalkectomy, the organ was occupied only by immature haemocytoblasts which had no granules in the cytoplasm, and the organ showed many mitotic division figures of young haemocytoblasts. On the fifth day, the histological structure of the organ showed a tendency to return to the same structure as that of a control crab. Thus, the effects of eyestalkectomy on a crab are considered to activate the leucopoietic organ temporarily and to cause a remarkable release of haemocytes from that organ.
