 outer cuticle present only at margins, inner cuticle showing polygonal cells divided by cracks; arrow indicates gap between them; SEM, x 125; D, inner 

 cuticle showing aggregation of vesicles in centre of cell, LM, x 750; E, inner cuticle showing cracks defining cell margins and raised impressions of
