The hemopoietic character of the "cephalic gland" in the crayfish Orconectes limosus.
Topographical, histological, and radioimmunological reinvestigations of the "cephalic gland" in the head of the crayfish Orconectes limosus demonstrated that this tissue is not of an endocrine nature. It is a part of the hemopoietic tissue and does not produce ecdysteroids.
