Convolutidae Polychoerus Notes

Mark EL 1892 (citation)-
Verrill AE 1893 (citation)- [ 510-11 gives description of genus. 
Bohmig L 1895 (citation)- lists in his family Aphanostomidae.
Graff L v 1902 (citation)- comparison with Amphicoerus- definition of.
Graff L v 1904-08 (citation)-
		"Convolutidae with ovary and yolk gland and many chitinous bursa nozzles.  Body flattened
	with one or more thread shaped tail appendages."
		"The lateral sides can be folded ventrally during swimming.  The mouth lies ventrally near
	the middle of the body, the pharynx is short.  The bursal nozzles (up to 50) are slender and
	thin walled, the testes are clustered in two lateral panels, each [follicle] remaining ?.
	Frontal gland is not know.  The  single species, living in the littoral zone, has two 
	posterior lobes and 1-5 posterior tails; they are up to 5 mm long and 2 mm wide".

Graff L v 1905 (citation)-
		"Convolutidae with yolk glands and ovaries and many chitinous bursa nozzles.  Body dorso-
	ventrally flattened, with one or more filamentous tail appendages.  Sides not enrolled.  The
	species belonging to this genus actually use the sides as a rudder and do not fold them
	ventrally when creeping or at rest.  They possess two caudal lobes as in 
	Amphiscolops langerhansii and besides 1-5 filamentouse appendages arising from the 
	posterior of the dorsal side between the lobes.  The testicular follicles though retaining
	their individuality are grouped in two lateral fields and form thus an intermediate 
	condition between scattered follicles and compact testes.  Concerning the frontal glands
	nothing is know.  Littoral"

Lohner L 1910 (citation)- definition of genus p 89- some change from Graff's definition.
Luther A 1912 (citation)- p 54 gives definition.
	"Convolutidae with female genital opening lying anterior to the male.  Bursa seminalis with
	many (to 50) laminated (lamelloren) nozzles.  Body dorso ventrally flattened.  Sides at rest
	and during creeping	not enrolled; with 1-5 thread-like tails."  [Bush translation]
