Guion's marl-bed, C. W. Johnson; Post-Pliocene of Simmons's Bluff, S. Car., 

 Burns ; living from the coast of North Carolina to Samana Bay, Santo 

 Domingo, in 15 to 63 fathoms. 



Shell with a smooth sinistral nucleus and six or more subsequent normal 

 whorls ; sculpture of numerous small, narrow, close-set, slightly oblique rib- 

 lets extending from the suture nearly to the pillar or umbilical region, with 

 spirally striate interspaces, the stronger striae tending to appear as if punctate; 

 whorls gently rounded, axially drawn out; suture appressed ; aperture small, 

 rounded in front; pillar slender, twisted. Lon. of shell 4.0; max. lat. I.o mm. 



This pretty little species has been represented in my collection for a 

 number of years by recent specimens. It is No. 612 of my list in Bulletin 

 37 U. S. Nat. Museum. The recent specimens are of a pale yet warm yellow 

 brown, with a tendency to spiral lines of a darker shade. 



It is somewhat singular that in the Older Miocene of the Chipola beds, 

 though many small shells were collected, but two forms of Turbonilla have 

 turned up. In the Red Bluff Eocene a T. mississippiensis, and in the Claiborn- 

 ian a T. neglecta, have been briefly described by O. Meyer (Geol. Surv. 

 Alabama, pp. 69-70, 1886) ; the " Chemnitzia " acttta of the same writer is a 

 Bittiiim allied to Alaba by several characters. 



Family CASSIDIDv4i (supplementary). 

 Genus CASSIS Lamarck. 



The group including Cassis proper and Cassidca Bruguiere (1789) had 

 been previously named Cassida by Brunnich (Z06I. Fund., p. 248, 1772), who, 

 however, did not name any species in connection with his diagnosis of the 

 genus. This name was adopted by Humphrey in 1797 to cover the Helmet 

 shells, and very possibly was the source of Cassidea Brug. In the same place 

 the genus Tonna is proposed for the shells since universally known under the 

 name of Dolium, Lamarck. Gray, in Griffith's Cuvier, alludes to this name, 

 which I have not seen elsewhere mentioned in the literature. Fortunately, 

 as no species was mentioned in connection with the table of genera, we are 

 not obliged to disinter these names, which for the rest long antedate those in 

 common use.

 C. {P.) globosmn Dall, Part I. p. 161, 1S90. 



Eocene of the Ocala nummulitic beds and Older Miocene of the Chipola 

 formation in Florida. 



In the Journal of the Academy of Natural Sciences, First Series, Volume 

 VII., p. 146, 1834, Conrad briefly describes a species of Cassis under the spe- 

 cific m.meoibrevicostatusjYomtht Claiborne sands. In 1865, in his cata- 

 logue of Eocene fossils (Am. Journ. Conch, i. p. 25), he refers it to Setni-
