 7.2 mm.; 23 whorls T. langfordi n. sp. 



18. A tubercular cord below the presutural band, causing it to

 arated by deep impressions across the intercostal intervals, 

 the upper cord widest; columella distinctly biplicate; a re- 

 curved basal channel; 30x6.7 mm., 17 whorls. 



T. waikikiensis n. sp. 



21. Small, slender forms with raised inner lip and rather fine spiral 



striae in the intervals of the strong ribs T. swainsoni Dh.

 sutural fasciole a strong cord, its upper slope somewhat grooved; 

 below it a much smaller cord followed by four (rarely three) unequal 

 spirals, traversed by unequal arcuate incremental striae. Base of 

 the last whorl with numerous smaller spirals. The aperture is 

 small, with strongly obhque anterior canal. Columella short, smooth.
