Genus CORALLIOPHILA H. and A. Adams 



CORALLIOPHILA LACTUCA Dall 



Coralliophila lactuca Dall, Bull. Mus. Comp. Zool., vol. 18, p. 220, pi. 16, 

 fig. 6, 1889. 



Off Fernandina, Fla., at station 2669, in 352 fathoms, sand, bottom 

 temperature, 43.7° F. Also off Cuba in the Gulf of Mexico in 152 to 

 229 fathoms, ooze, bottom temperature, 49.5° F. 



This was found so near station 2668 that it seemed proper to in- 

 clude it. 



Subfamily Thaisinae 



Genus THAIS Bolten 



THAIS FLORIDANA Conrad 



Purpura floridana Conrad, Journ. Acad. Nat. Sci. Phila., ser. 1, vol. 7, p 

 265, pi. 20, fig. 21, 1837. 

 Off Fernandina, one very young dead specimen. 

 This specimen was evidently due to drift from the shore or dis- 

 gorgement by some fish or bird. 



Family EPITONIIDAE 



Genus EPITONIUM Bolten 



EPITONIUM MARCOENSE, new species 



Shell small, white, acute with a translucent nucleus of three and 

 six subsequent rounded adjacent whorls; axial sculpture of (on the 

 last whorl about 22) low thin sharp simple varices with wider inter- 

 spaces and not continuous over the suture; spiral sculpture of almost 

 microscopic fine striae, uniform over the whorls; base with no disk, 

 aperture nearly circular. Length, 8; diameter, 3 mm. U. S. Nat* 

 Mus. Cat. No. 108017. 



Off Fernandina, 10 specimens, mostly young; off Georgia six 

 specimens. Beach at Marco, Fla., common; Olson. 



The spiral striation is only visible under a lens in a good light. 



EPITONIUM FRACTUM, new species 



Shell small, decollate, with four well-rounded whorls remaining, 

 with a dull surface, white, and rather laxly coiled; suture distinct, 

 deep; axial sculpture of (on the last whorl 13) thin low slightly ob- 

 lique sharp lamellae, continuous in the depth of the suture and up 

 the spire, making about one-third of a turn around the shell; there 

 is no spiral sculpture (though the edges of the lamellae look more or 

 less irregular, it may be due to wear) ; the base is evenly rounded 

 without a disk, and imperforate; aperture rounded with a thin 

 slightly expanded margin. Length of four whorls, 9.5; of aperture, 3; 

 diameter, 4 mm. U. S. Nat. Mus. Cat. No. 108015. 



Off Fernandina, one specimen.
