The cuticle of Asaphus raniceps Dalman has been examined with the scanning electron microscope after preparation by breaking and etching. Three main zones are denned on differences in appearance and dimensions of laminar units. Some details of the fine structure of laminar units are described. The presence of an organic framework within the cuticle is confirmed. The laminae and organization of the cuticle of this species are considered comparable to those of many extant arthropod cuticles.
