Shell globosely conical, of a pale colour, with rows of

 ward ; suture deep ; aperture circular ; peritreme double, 

 continuous, the internal simple, standing forward, the external 

 narrow, spreading; umbilicus small ; operculum spiral, con-

T. oblonga, pallida, spira decollata ; anfractibus 3 — 4, teren- 

 tibus, confertissime decussato-striatis, asperis ; sutura pro- 

 funda ; apertura circulari ; peritremate dilatato, late expanso,

Shell of an oblong, somewhat conical form, with a decol- 

 lated spire, consisting of three or four rounded volutions, 

 which are rough all over, with close set decussating striaa ; 

 suture deep ; aperture circular ; peritreme dilated, spreading 

 widely, rather flat, crenated, the upper part sometimes re- 

 flected ; umbilicus small, externally with a spiral, reflected, 

 striated lamella. This is undoubtedly Linne's Turbo Lincina, 

 with which Lamarck's Cycl. Lincinella and his Cycl. inter- 

 rupta, have both been confounded, neither of which, however, 

 agrees with the character Linne gives of his T. Lincina, viz. 

 T. testa oblonga, obtusa, rugoso striata, apertura limbo dilatato 

 piano crenato. Jamaica.
