The pericardial organs of an anomuran (P. brevipes) and of a brachyuran (T. cheiragonus) were observed with the use of vital staining method of methylene blue. The organs of P. brevipes consist of several trunks lying on both sides of the heart in the pericardial cavity, the trunks being anastomosing with each other. On the other hand, the organs of T. cheiragonus are characterized by two large bodies (anterior and posteior bars) and two trunks which communicate each other between the two bars. The histological observations on the pericardial organs were made and the production of a colloidal substance in the tissues of the organs was detected. The colloidal substance is stained with acid fuchsin in the early stage of its formation process in the cell nucleus, and becomes orange G stainable after discharge. Thus, the process of the production of the colloidal substance in the pericardial organs highly resembles that of colloid A, B, and C in the sinus glands in the eyestalks of Sesarma (Enami '51). It is probable that the colloidal substance produced in the pericardial organs corresponds to a hormone on which Alexandrowicz and Carlisle ('53) have studied experimentally in Crustacea.
