MIDLAYER IS VARIABLE THICKNESS \& SHAPE WITH FIBRILLAR STRUCTURES. INTERNAL LAYER THICKEST \& MAKE OF SUCCESSIVE LAYERS OF FIBER BUNDLES, PARELLEL IN SAME LAYER. IN SIP.N. BUNDLES INTERSECT AT RIGHT ANGLES TO EACH OTHER. MICROVILLI FROM SUBJACENT EPIDERMAL CELLS PENETRATE CUTICLE, MORE OR LESS DEEPLY BUT NEVER REACH THE EXTERNAL MEDIUM. MICROVILLAR \& FIBRILAR SYSTEMS ARE EMBEDDED IN A GRANULO-FILAMENTOUS MATRIX, THIS MATRIX WITH ELECTRON OPAQUE PARTICLES IN G.V. EPIDERM HAS ATTACHMENT DEVICES. FROM PHYLOGENETIC POINT OF VIEW THIS EPIDERMAL ARCHITECTURE IS VERY SIMILAR TO THAT OF THE ANNELIDS (ESPEC. POLYCH) AND THE POGONOPHORA.},
