end; outer lip thickened, toothed Inside 

 with one denticle upon opposite side; color

 dubious but it probably lives among the 

 Keys.

Shell small, aperture long and nar- 

 row; outer lip thickened, particularly in 

 the middle, toothed; inner lip crenulated; 

 operculum very small.

SUBGENUS COLUMBELLA Lamarck 1799 



PYRENE MERCATORIA Linne. Trader Pyrene. 

 Shell oval, thick, color variable; spire 

 short; whorls five to six, spirally grooved; 

 aperture two-thirds length of shell; outer 

 lip strongly toothed inside; columella with 

 about six small teeth below, two to three 

 larger teeth above. Length 17 mm.

PYRENE RUSTICOIDES Heilprin. Rustic Pyrene. 

 Shell smooth, white or orange color with 

 white angular star-like spots near suture; 

 spire short and sharp; whorls seven; outer 

 lip with small white teeth; interstices of 

 teeth dark chocolate color; epidermis hairy. 

 Length 18 ram. 



The dark spaces between the teeth 

 separate this from the preceding with which 

 it might readily be confused. An European 

 Pyrene, P. rustica, is similar to but not 

 identical with this species.

 ored, with only about ten ribs to the whorl 

 and spindle-shaped.
