Turriciila differs from Mitra in being longitudinally 

 ribbed, and in the outer lip being striated within. The 

 species live in exposed situations on the reefs, or crawl 

 about the clear coral-sands in shallow bays and inlets. 

 In this group the teeth, as shown by Dr. Gray, most 

 resemble those of the Muricidte, the lateral teeth being 

 flat, with a bent-up process at the end more or less at 

 right angles with the base.
