Of the second complex of fibrils, its outer component, unlike the outer

 only the lower half of the funnel portion of the body (Fig. 80) . Toward 

 the ciliary ring it disappears and, according to Entz (1893), reappears 

 actually to form this ciliary ring "out of a number of fine fibrils (Myone-
