According to Lischke (Ja[)Ui. Jleeros-Conch , v. 3, p. lOiJ). this species is 

 not synonynions witli Cardiura bnllatuni Lamarck, and of Keevo. hut to C. 

 riigatnm of these antliors ijuoted hy the fArmer in liis Histoire Naturelle p|i , 2d 

 ed, vol. G, p. 393, and figured hy the latter in the Icon. Concli., Cardiuni, pi. 12, 

 f. 63. It has heen given, as Lischke says, luuler the same name Viy Menschen 

 in the Zoophylacinm Gronoviannm vol. 3, p. 2(5t!, no 112.3, pi. IS, f. .'S, and hy 

 Lischke. Without entering into this queslion, I menticm only the tew speci- 

 mens, mostly broken, which were found at, Oji. They are thin, suhspherical, 

 nearly circular in outline, not much elongated hehind. The snrlace is very 

 delicately radiated and concentrically striated. Fnlvi-i centifilosa Carpentci-, 

 perhaps only a variety of Cardiuni ( [.a.'vicavdium) modestuin, dilVers hy having 

 weaker radii behind, whilst our species does not show any ditftrence lictween 

 both ends of the shell.

The small species, rounded, not cpiite eijuiiateral, a little elongated behind, 

 covered with strong coiicentrical stri.x and a very line and minute railial strialion 

 and with the tyincal liinge of the genus, has been already idriititicd by Lischke. 

 The diagnoses of the numerous species of this genus given by (iould are all dif- 

 ferent. A few specimens only were found at </)i, but at Shiaagawa the species 

 was met with in a larger number of siiecinicns.
