T. tuberosa, Reeve (hg. ()22) is the young of this species, and 

 a very immature specimen of it appears to be described and 

 figured l)y Kiister as T. elegantula (fig. (525). *

Smooth, plicatel}^ ribbed, ribs angular, three or four revolving 

 granulous stria? at base. Ash, chestnut, etc., with a broad white 

 zone around the suture, and narrower ones marking the basal 

 stria*, or entire base white. Length, "6 inch. 



Philippines, Viti and Samoa Islands. 



Differs from the preceding species in the longitudinal ribs 

 being continuous over the body-whorl, less tuberculate above, 

 closer and narrower, in the want of revolving sculpture except 

 at the base ; the coloring is essentially the same, and it may be 

 only a variety of T. patTiarchalis. 



T. OsiDiRis, Issel. PI. 56, ligs. 627, 628. 



White, with a central chestnut or chocolate band. 

 Length, '9 inch. 



Red Sea. 



With longer spire and somewhat different coloring, this is 

 vei'y closely allied to the preceding species ; it differs from T. 

 cadaverosa by its broader liand and want of revolving sculpture, 

 but appears to be intermediate between it and porphyretica. T. 

 umbonata^ Sowb. (fig. 628), is a synonym.
