Hutton. — On Ehachiglossate Mollusca. 229 



Whorls angled and spirally striated, with seven or eight longitudinal 

 ribs in front of the angle, and tuberculated on the angle. 



The dentition and operculum are figured in the Trans. N.Z. Institute, 

 xv., pi. xiii., f. f. The operculum is also figured by Quoy, and the dentition 

 by Troschel, but he makes it different ; probably he has mistaken the 

 species.
