The genus Paraparchites is closely related to and probably derived from Aparchites. 

 In the latter the ventral edges of the valves meet without appreciable or, at any rate, 

 constant overlap, and it is this difference' that is chiefly relied on to distinguish the 

 two genera. 



The authors refer the Ordovician species Aparchites cUiptia Ulrich, to this genus. 



and Bassler (Ray S.) New American PaUvozoic Ostracoda.
