Convoluta dubia Notes


Brauner K 1926 (citation)- gives illustration of this species on plate V.  One example differs from
	Monocherus chuni in femal reproductive organ.  Male reproductive organ is so changed as to not
	be able to be defined.  Specimen badly crumpled but length about 1.2 mm.  
	- Epidermis - usual cilia 5-6.5 micrometers - missing on ventral side.  
		9 micrometers dorsal 4-5 micrometers ventral.  Glands on dorsal side and anterior.  
		lacking on ventral (stain reddish) and posterior. 
		[Illustration looks like rhabdite gland].  glands also empty [muscous?] 
	- Well developed frontal organ - opening distinct in cilia free area at anterior end, fills
		out 1/4 of body, stains blue.
	- Muscle layer- circular and logitudinal - doesn't say which is outer, dorso-ventral.
	- Mouth- slightly before middle - at first glance difficult to tell from penis.  Muscle around
		this.  Opens into digestive parenchyma- [ill fig 17 poor].
	- Parenchyma - out and central.  "rand" "zentral".
	- Brain - 2 well developed ganglia paired dorsal and paired median nerves ventral and between
		these - statocyst.  
	- Sense organ on ventral side with nerves from ganglia similar one in M. chuni.
	- Female copulatory organ- paired ovaries - eggs on ventral side to 10-15 micrometers.  Bursa
		- see illustration - no vagina or female pore - a split in parenchyma ny = ?
	- Male reproductive organ- couldn't find sperm in testes.  Male organ involuted- animal
		was at beginning of female reproductive.  Penis	with muscle layer (outer circular, inner
		circular and longitudinal in between - a double cellular canal [Bush = ductus ejactus ?].
		Cilia on outer wall at one side [Bush- is this in male antrium].  He concludes is a 
		species dubia here name - belonging to Convoluta.

Marcus E 1948 (citation)- mentions this in describing Convoluta vexillaria, p 116. 
Dorjes J 1968 (citation)- says species dubia.
