Bresslau E 1933 (citation)- p 61, figure 33, detail of epithelium, etc.- from 18-20 meters of water
	(brackish 0.5 %), also p 117, figure 111 for reproductive organs.

	"(ventral view) with bright yellow-brown, club shaped pigment plugs, occuring as rod shaped 
	bodies arrayed in close longitudinal rows and intercellularly in the parenchyma thru the 
	epithelium to ? in the ciliary zone.  Anterior to the genital pore usually 6 (3-7) bursa lying side
	by side across the animal of a similar structure to those in Convoluta convoluta.  Passage of sperm 
	thru parenchymal spaces." [Bush- does this caption constitute a description? ok] [Bush- note
	also frontal gland testes and ovary down each side and genital pore at posterior end in illustration].

	Anaperus balticus figure 1D, with partial descirpiton- Palmenia (Palmeniola) balticus as synonym,
