Aporocotyle simplex Odhner, 1900 



Hosts: Sebastodes sp. B.C. McFarlane, 1936 



Sebastodes maliger Wash. Ching, 1960b

 the Russian arctic (Skrjabin, 1951). 



Morphology: This form was redescribed by McFarlane (1936) and figured and 

 described by Skrjabin (1951). Nothing is known of the life cycle of this 

 genus. 



Sanguinicola klamathensis Wales, 1958 



Host : Salmo clarki henshawi Ore. Wales, 1958 



This is the only record of this trematode. 



Biology: Furcocercous cercariae develop in Flumenicola virens, penetrate fish, 

 and mature in the veins of the gills. Miracidia being released cause damage 

 to the gills and heavy mortality to fish hosts (Wales, 1958).
