Mya ovalis [Lightfoot, 1786], p. 134. 



Mya batava Dillwyn, 1823, p. 13 (not Maton and Rackett, 1807.) 



Unio cytherea Kiister, 1833. 



Unto crassa cytherea Kuster. — Haas, 1940, p. 129. 



Mya ovalis S.— Dall, 1921, p. 128 (in part). 



Not Mya ovalis Pulteney, 1799 (=Unio pictorum Linnaeus, 1758). 

 A comparison of the figure in Lister, which is accompanied by the 

 words "a Danubio," with various figures and descriptions of the 

 polymorphic species and subspecies of Unio occurring in Europe leads 

 me to the conclusion that Lightfoot's name must be used for the 

 subspecies that Haas (1940) called Unio crassus cytherea Kuster, 1833. 

 Because the name ovalis is two years older than crassus, the central 

 European, Danubian form becomes the nominate form, and the 

 western European subspecies becomes Unio ovalis crassus Retzius. 

 I leave the judgment of the correctness of this assignment to my 

 European colleagues more familiar with this difficult freshwater fauna.
