 Inhabits Jamaica, and is a land shell. Browne. 

 Shell about sixteen lines long and twelve broad, of a brownish 



colour, or sometimes white spotted with brown, and the 



marginated outer lip white ; it appears by his references that 



Linneeus considered this to be a Variety of T. hincinttf 



from which it principally differs in being much larger, and 



in having the aperture more dilated. 



LUNULATUS. HO. Shell cylindrical, with reticu- 

 lated striae, and the aperture detached.

 p. 363. 



Inhabits 



Shell seven lines long and four and a half broad, white, with 

 four or five transverse rows of reddish moon-shaped spots ; 

 from Mulier's description it appears to be most allied to T. 

 elegans, but the body-whirl is extended so that the aperture 

 is detached from the spire, and the reticulated striae are less 

 prominent. 



LiGATUS. 120. Shell sub-umbilicated, nearly glo- 

 bular, acuminated, and the aperture thickish 

 in the margin.
