DIPYGUS (from the Greek dis twice and pyge buttocks), a type of symmetrical double monstrosity (see), the basis of which is seemingly a splitting of the caudal end of the embryo (duplicitas posterior); such monsters are joined by a common head and trunk, but possess separate spines; the lower part of the trunk is double with two pairs of extremities. A distinction is made between Dipygus dibrachius (with two arms), Dipygus tribrachius (with three arms), and Dipygus tetrabrachius (with four arms).
