Genus CHORl STELLA Bush 



pompholyx Dall, Bull. M. C. Z., 18, p. 394, pi 28, f. 9, '89, (as 

 Cyclostrema)', Bull. 37, U. S. N. M., p. 166, pi. 28, f. 9, 

 '89; Bush, Tr. Conn. Acad. Sci., 10, pp. 99, 140, 1899- 

 1900. 



Distribution. — Blake Station 2, Gulf of Mexico, type locali- 

 ty. Also Fernandina, Florida, to Cuba. 294-805 fms. 

 Note. — This species is referred tentatively to Choristella as 

 Miss Bush suggested that it might prove referable to this 

 genus. 



Genus EPICYNIA Moerch 



multicarinata Stimpson, MS., Dall, Bull. M. C. Z., 18, pp. 273, 

 392, '89; Bull. 37, U. S. N. M., p. 166, '89, (as Vitrinella)\ 

 Bush, Tr. Conn. Acad., 10, p, 112, '99-1900. 



Distribution. — Hatteras to West Florida. Pliocene, Caloosa- 

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

 Perhaps identical with the Architectonica gemma of Holmes 

 listed by Hilgard from the Lake Borgne borings. La. 



Genus ETHALIA A. Adams 



The following species are of doubtful generic position. They 

 were excluded irom Ethalia by 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.
