 hatchie beds,' Fla. Upper Miocene, Duplin Co., N. Car. 

 Perhaps identical with the Architedonica gemma of Holmes 

 listed by Hilgard from the lyake Borgne borings, La. 



Genus ETHALSA A. Adams 



The following species are of doubtful generic position. They 

 were excluded irora. Ethalia bj^ Pilsbry (Man. Conch., 11, 

 p. 457) when he restricted that genus and gave Ethalia 

 guamensis Quoy and Gaimard, as the genotype. Dr. 

 Dall has referred me to Miss Bush's revision (Trans. Conn. 

 Acad. Sci., 10, p. 116, '89-1900). Apparently she tentative- 

 ly retains these three species in Ethalia.
