 tudinal ribs, and sometimes dcA'eloping two or three nodules 

 }»etween the varices. Length, 1 to 1-5 inches. 



Philippines to Sandwich Islands ; Paumotus. 



More graceful in form, with more rapidly accuminated spire 

 and longer canal, and smaller than T. ruhecula ; — to Avhichj 

 nevertheless, it is closely allied. T. mimdum Gould, (figs. 4.3. 

 44), appears to be the same species.

Described as a distinct species Itut the characters by which 

 Mijrch distinguislies it are common to the type form except the 

 shorter spire and more rugose longitudinal ribs. Probably not 

 perfectly acclimated, and depauperate in consequence.
