The following is J. C. Merriam 's original description of T. diversi- 

 lineata : 



Shell medium in size. The imperfect type specimen shows seven flattened 

 whorls, which are strongly beveled below. Flattened sides ornamented by five 

 revolving ribs, of which the lowest, standing on the angle of the whorl, is much 

 stronger than the others. On some of the whorls there are indications of revolv- 

 ing sculpture on the beveled surface between the lowest rib and the suture. 

 Locality, Carmanah Point, Vancouver Island. 



This species is very common in Oregon and Washington ; it is 

 found on Vancouver Island at Carmanah Point, from which locality 

 Merriam obtained the type specimen. It is common in the Blakely 

 beds, as described by C. E. Weaver, in the region of Puget Sound. 



T. porterensis Weaver 139 is very close to this species ; the typical 

 T. porterensis differs from the typical T. diversilineata in that the 



139 for original description of T. porterensis, see Weaver, C. E., Wash. State 

 Geol. Surv., Bull. 15, p. 73, pi. 11, figs. 83, 84, 1912.
