Notes for Convolutidae Amphiscolops

Graff L v 1891 (citation)- new genus and places Convoluta cinereus Graff in it.
Bohmig L 1895 (citation)- lists in his Family Aphanostomidae p 39, also p 10, 13, 14, 20, 35.
Graff L v 1902 (citation)- distinction between this genus and Polychoerus- this has ovaries
	(polychoerus has ovaries and yolk glands seperate).

Graff L v 1904 (citation)- definition of genus.	
Graff L v 1904 (citation)-  "Convolutidae with ovaries and two or more chitinous bursa nozzles.  
	Dorsoventrally flattened, side parts not rolled up.  With ventral mouth and copulatory
	organs pushed far to the posterior.  Frontal glands well developed, testicular follicles
	scattered.  One species (A. langerhansii) possesses a pair of short flat tail lobes.
	Flat creeping animals, 1-5 mm long.  Littoral."
							Tierreich - Graff L v 1905 (citation)- 3 species.

Bohmig L 1908 (citation)- mentions p 6, 7.
Luther A 1912 (citation)-  p 53-4 diagnosis:
	"Convolutidae with genital opening lying anterior to the male.  Bursa seminalis with many
	(2-14) laminated nozzles.  Body "dorso-ventally vlattened, the sides not enrolled' without
	thread-like tails."  footnote- "In this genus I place also Heterochoerus australis 
	Haswell (1905).  
		It would be best ot split the genus Amphiscolops in the future as to whether the bursal
	nozzles open into the parenchyma or intor the female antrum.  I have omitted this here, since
	in this respect no reports are available concerning A. virescens."  
		Also compared with his genus Palmenia.

Wilhelmi J 1913 (citation)- lists p 12 as Amphiscolops (Amphicoerus) Graff
Marcus E 1947 (citation)- notes on the genus p 161-2.
Marcus E 1948 (citation)- mentions p 112, 187.
Westblad E 1948 (citation)- p 30 discusses variety of nozzles here and his reason for removing
	A. virescens and placing it in Aphanostoma.  p 46 mentions bursal nozzle in this.  p 54 should
	this be close to a ?? in Polychoerus.  p 57 in key.
								
Marcus E 1950 (citation)- defines genus as compared to others of Convolutidae as having 2 or more
	bursal nozzles but distinct from Polychoerus since it has no caudal appendages (tails)-
	p 18, 21 key.
	
Hyman LH 1951 (citation) -vol 2, p 122- diagram of reproductive organs.  p 126 and 127 copulation
	and egg masses.  p 128- notes caudal lobes in.  p 129- notes this species lives on 
	sargassum.
