The following code symbols for Trematoda are based on a single scheme, marked by (1). 

 Included, however, are certain other commonly encountered names of groups in which the Trematoda 

 have been classified by other schemes, marked by (0) and (X). 



42 Trematoda, class of Platyhelminthes 

 42 (1) (O) Digenea, subclass of class Trematoda 



42 (X) Digenea, order of class Trematoda. (When Digenea is treated by the author as an 



order, it is equivalent to the combination of the five orders as listed here. Symbols 

 421, 422, 423, 424, and 425 and equivalent to Digenea as a subclass. Symbol 42. ) 



42 (1) Anepitheliocystidia, superorder of subclass Digenea 



42 (X) Prosostomata, a suborder of order Digenea. (The suborder was conceived to include 



all digenetic families except Bucephalidae. Since in this list, the Bucephalidae are 

 not separated into a distinct suborder, but are included with the order Strigeatoidea, 

 Prosostomata here is essentially equivalent to Digenea, Symbol 42. ) 



42 (0) Prosostomata, an order of subclass Digenea. (Equivalent to Prosostomata as a 



suborder of order Digenea and equivalent to Digenea minus Bucephalidae. )
