Electron microscopic techniques were adopted to study the epidermal cuticle of 4 species of brazilian earthworms. Basically this structure consists of collagenous fibers arranged in alternate layers and embedded in an amorphous and fibrillar matrix. Of characteristics, the ellipsoidal projections of the cuticle of P. hawayana were found to be enclosed between 2 parallel layers, where each layer consists of 2 electron dense lines, separated by a space filled with an electron dense material.
