which sometimes terminate in faint divarications or obscure pustulations ; the 

 surface of the whole shell covered with a polished coat of enamel, obscuring 

 the sutures, as in Dipsaccus or Cyprcea.

Caloosahatchie beds, not common. 



In the original specimen of this elegant shell the enamel on the body was 

 more or less decorticated and the usual spiral sculpture of the canal and body, 

 running into the aperture, presented somewhat the aspect of Mazzalitia 

 or Lagena. This misled Prof. Heilprin in referring the shell to its generic 

 place. An examination of Conrad's type-specimen o'i Mazsalinacoviv\x\cQs me 

 that it is entirely distinct from this shell, though its relations would be with 

 /vzi'«^/rt;7'a and its allies. The present species is distinctly a i<aj«'ci/ar/'«, with 

 an envelope of enamel which must have been applied by an extension of the 

 mantle not known in Fasciolaria proper. The plaits are normally three, but 

 very old specimens show some obscure bifurcations of the callus near their ter- 

 minations. There are no plaits on the upper part of the pillar or on the body ; 

 the pillar is deeply arcuate and the canal extremely short, while the doubly 

 arcuate outer lip is thin and sharp and the throat profusely and finely lirate. 

 The fossils show no traces of any color-pattern. The sutures and nucleus are 

 hidden under the profuse and brilliant enamel.

Caloosahatchie beds, rare. Post-Pliocene of the Carolina coast. Recent 

 on the coast of the United States from North Carolina to Florida and south- 

 ward to Venezuela and St. Thomas. 



This species is distinguished from F. distaushy its color-pattern; its spiral 

 sculpture, especially several grooves which slightly appress the whorl in front 

 of the suture ; by the absence of any internal ridge on the body in front of 

 the suture ; the ornamentation of its ovicapsules, and its normally larger size 

 and lighter construction when adult. 



A specimen exactly agreeing with the recent form, with the whole surface 

 grooved spirally, was obtained from the marls. 



Mr. W. M. Gabb (Journ. Acad. Nat. Sci., 2d series, viii. p. 354, 1874) took 

 the hasty and inaccurate view that F. tulipa, F. distans and the fossil F. semi- 

 striaia and F. rlioviboidea Rogers were one and the same species. F. semistriata
