 (1948). 



Biology: Virgulate xiphidiocercariae develop in sporocysts in Flumenicola virens

 Pacific Northwest.

Opechona alaskensis Ward and Fillingham, 1934

Opechona occidentalis Montgomery, 1957

 California. It was described by McFarlane but more completely described by 

 Montgomery. The life cycle is unknown, but Lebour (1916) found late cercarial 

 stages of what appeared to be O. bacillaris in a number of coelenterates.
