Graff L v 1905 (citation)-p 13.
	"Convolutidae with one chitinous nozzle and an ovary.  Body usually flattened, often with the
	sides rolling up to form a tube.  The frontal glands open either scattered or in a sharply 
	marked out area, with or without a frontal organ.  The mouth lies ventrally in the posterior
	end of the first or in the second third of the body and only C. roscoffensis distinguished
	for its ribbon-like form carries it at the posterior end of the first eighth of the body.
	The pharynbx is usually very short and only in C. convoluta is developed as long tube.  The 
	two genital openings lie always on the ventral side of the posterior half of the body, the bursal
	nozzle appears as a thickwalled, keg or usually very flattened with broadened sides which in
	life are more or less enrolled onto the ventral side so that the extreme of such a form
	presents a tube or cylinder form.  In these the lateral edges usually carry nerve endings (sensory
	edges) and only in such do we find the numerous, ventral, many celled, flask shaped organs 
	(C. sordida? C. groenlandica, ?C. flavibacillum); also these have paired oral and genital 
	poison organs provided with chitinous spones (C. convoluta, C. hipparchia, C. borealis, 
	C. bimaculata).  Neither ovaries nor testes possess a tunica propria.  In this genera belong
	the largest Acoela, the length of some species reaching from 0.62-9 mm.  Mostly littoral, 
	sometimes pelagic."  Teirreich - Graff 1905 13 sp.

  		without poison or stimulating organs.  Brain sunken inward.  Anterior glands usually joined
  		into a frontal organ.  Lateral edges usually very enrolled ("einschlagbar"=?).  Inclusions of
