riigosuDi (Conrad) and the recent F. canaLicidahiin Linne. The former is 

 Miocene, from the Carolinas northward, the latter is found in the same area of 

 the Phocene and Post-Pliocene, and may extend farther south, but I have not 

 seen it from the Pliocene of Florida. 



Fulg-ur (pyrum var. ?) planulatum n. s. 



Shell Creek, Willcox, Caloosahatchie marls, Dall. 



Shell small, six-whorled, with a small, smooth nucleus of one and a half 

 whorls ; the very small whorls immediately following the nucleus are spirally 

 striate, with a flattish, relatively broad, minutely undulate or granular keel at 

 the shoulder, behind which the whorl is flattish or slightly excavated, with a 

 narrow and very feeble channel at the suture ; beyond this the tubercles, keel 

 and channel become obsolete, the shoulder subangular or almost rounded, the 

 posterior surface of the whorls flat and smooth, and in front of the suture, which 

 is wound on the exact periphery, there is only the faintest possible depression 

 or rather downward slope to the preceding whorl ; except for a few sparse, 

 obsolete spiral lines, the periphery is smooth ; the somewhat constricted base 

 of the whorl is spirally threaded, with a tendency to alternation in strength ; 

 canal long, m.oderately slender ; outer lip meeting the periphery nearly at 

 right angles, simple, sharp-edged, nearly straight ; body with little callus, 

 pillar callous at the edge, sharply grooved ; throat not Urate inside. Lon. 54, 

 lat. 31 mm. 



This shell is exactly intermediate between the channelled and the un- 

 channelled Fulgurs. If a specimen of pyrum with a scalar spire were to have 

 the top of the whorls levelled off, the periphery become smooth and lose the 

 lirs of the outer lip, it would be something like this shell. One was found 

 at Shell Creek by Mr. Willcox and one on the Caloosahatchie by the writer. 

 It does not seem possible that pyrum could vary to this extent, yet there is 

 nothing else to compare it to, and the paucity of material makes me hesitate 

 to regard it as absolutely distinct. 



Fulgur stellatum. n. s. 

 Plate 4, figure 9. 



Miocene silex-beds of Ballast Pt., Tampa Bay, Florida. 



Shell thin, attaining about eight whorls ; nucleus large, smooth and 

 swollen, of about two whorls ; succeeding whorls encircled by a thin, round- 

 edged keel, neatly divided in the early whorls into about a dozen even, sub- 

 equal, triangular, flattened rays, with equal interspaces, stellate when viewed 

 from above; the surface of the whorl behind the keel smooth, excavated 

 moderately and rising at a low angle to the suture, which is not appressed, 

 and is hidden under the shadow of the keel of the preceding whorl; on the 

 last whorl in the adult the keel between the radii is less pronounced, but the 

 flat spines retain much of the same character ; in front of the keel in the
