Note.— In the synopsis of the Carditacea, in Proc. Acad. Nat. Sciences of Philadel- 

 phia for 1902, p. 700, the name Jfiodon Carpenter, 18(54, was ad(3pted for a subgenus 

 of Vrneri cardia. It appears that this name was used l)y Dumeril for a iish before it 

 was proposed by Carpenter for the mollusk, and I have therefore proposed for Car- 

 penter's Miodon the new name Miodontisms. For the section of Fn-ebra, commonly 

 called Acus, also a preoccupied name, I now suggest the designation of <t.n/,mris.
