Genus NASSARIA Link. 



Subgenus Nassarina Dall. 



Nassarina glypta Bush. 

 Plate 9, figure 11. 

 Mangilia ? glypta Bush, Trans. Conn. Acad. vi. p. 461, pi. xlv. figs. 5, 5 a, 1885. 

 Nassaiina glypta Dall, Blake Gastr., p. 181, 1889. 



Pliocene beds of Shell Creek and the Caloosahatchie. Recent from Cape 

 Hatteras to the Florida Keys in 14-63 fathoms. 



The fossil form is identical with the recent one and as it has not been well 

 figured I have added a good figure of the species. 



From an examination of Gabb's type of Mctulella I am inclined to think 

 that group will eventually be classed in the vicinity oi Nassarina. 



Family NASSIDyE. 

 Genus NASSA Lamarck. 

 Nassa vibex Say. 

 A'assa vibex Say, Tryon, Am. Marine Conch., p. 34, pi. 7, figs. 52, 53, 1873. 

 Nassa vibex Say, Journ. Acad. Nat. Sci. Phila. ii. p. 231, 1822. 

 Nassa freten sis Perkins, Proc. B. S. N. H. 1S69, p. 117. 



Shell Creek and Caloosahatchie Pliocene beds, Heilprin, Dall and Willcox. 

 Post-Pliocene of the Myakka River and North Creek. Recent Atlantic coast. 



The species is not very abundant in the marl and varies very much in size, 

 the largest specimen I have is larger than any recent specimen in the museum. 



Nassa consensa Ravenel. 

 Nassa cotisensa Ravenel, Proc. Acad. Nat. Sci. Phila. 1861, p. 43; Tryon, Am. Mar. Conch., 



P- 35, 1873- 

 ? Buccinum niultilineatum Emmons, Rep. N. Car. Geol. Sur., p. 256, fig. 124, 1858 ; not of 



Marrat (1877). 



Cape Fear marls, North Carolina?, Caloosahatchie beds. Recent off the 

 Atlantic coast of the United States from Hatteras to Florida. 



Emmons' figure is rude, but characteristic. It differs chiefly from the re- 

 cent and fossil N. consensa by being proportionally more elevated. 



In the absence of any authentic specimen of Emmons' species and the 

 above-mentioned difference, I forbear to unite them. 



This species, both by color and fine, even sculpture, is now recognized and 

 distinguished by most American naturalists, though we have not yet any very 

 good figure of it. Its nearest relative is N. anibigita Mtg., which, as a rule, is 

 smaller and much more coarsely sculptured.
