TURRITELLA HALENSIS. new species. 



Plate 86, fig. 9. 



Only a mold of about five whorls of this species is available, but 

 the sculpture differs from that of any of the Tampa species and it 

 therefore seems proper to describe it. The whorls increase in diam- 

 eter very slowly and overhang somewhat at the suture. The spiral 

 sculptm'e comprises on the best preserved whorl two or three minor 

 threads in front of the suture; then one simple, more elevated major 

 spiral; then a constriction carrying two minor threads with equal 

 interspaces, in which are a few faint spiral striae; then a stronger and 

 more prominent major spiral, simple and forming the periphery of 

 the whorl ; this spiral grows proportionately more prominent as the 

 whorls succeed one another. In front of this and separated by a 

 faintly spirally striated equal interspace is a third simple major 

 spiral overhanging the next suture, and which in the earlier whorls 

 is about equal in strength to the major spiral behind it, but in the 

 later ones is somewhat weaker. Height of the three best preserved 

 whorls, 21; diameter of the earlier of the three, 9.5; of the latest of 

 the tlu'ee, 14 mm. The base and apex of the shell are defective.
