The characters of the genus Basistoma arc given in this place; but, as the full article in 

 the Transactions was published before No. 48 of the Proceedings, the date of the publication 

 of the Proceedings amounts to little in determining priority of description. The rest of the 

 article in the Proceedings consists of a list of the species without descriptions.

"In the examination of the Molluscs of the Imperial Cabinet of Vienna, I observed a 

 specimen of the funiily Xaiades, which I immediately recognized to be Mya nodulosa, 

 descTibed and figured by Wood (General Conchology and Index Testaceorum), and which 

 was placed by me among the nodulous C^nioTies in my Synopsis. * * * * * 

 The inspection of the specimen, however, enabled me at once to place the species in its 

 proper position in the system, the teeth, particularly the lateral ones, having equal and 

 parallel striae, as in the genus Prisodon, Hchnra. = Castalia, Lam. The cardinal and lateral 

 teeth are both robust, and of the form of the ponderous subrotund Uniones, but the deeply- 

 impressed striiE separate it from that genus and place it in Prisodon."
