The latest name that Dr. Stanton gives to this species is Meretrix vari- 

 ans, but it would appear to be preoccupied. The names Meretrix and 

 Cytherea were given by Lamarck at different times to the same genus, and 

 Hanley, in 1844, described a recent marine shell, under the name Cyth- 

 erea varians, in the proceedings of the Linnsean Society, and figured it on 

 Plate 15, figure 33, of his Illustrated and Descriptive Catalogue of Recent 

 Bivalve Shells, an appendix to Wood's Index Testaceologicus. For these 

 references the writer is indebted to Dr. Dall, who writes that " the name 

 Cytherea must give way to Meretrix, if for no other reason than because 

 Cytherea was used by Fabricius for Diptera a year before Lamarck used 

 it for a mollusk. It is true Bolten used it before either of them, but Bol- 

 ten's Cytherea is a totally distinct thing from Lamarck's."
