So far we have observed this species only at Woods bluff, 

 though it doubtless will be found elsewhere at a similar horizon. 

 In the type specimen the varices happen to be continuous, one 

 above the other, but that is not true of the specimen herewith 

 figured. In this, the varices of each succeeding whorl surpass 

 those of the w^horl before by one rib-space. It seems that Fischer 

 is right in referring ^'Ranclla" gigantca of the Mediterranean to 

 the genus Triton, on account of its lack of a posterior canal. 

 The species tuomeyi certainly falls in the same group with 

 gig ait tea. 



This differs from shoiualteri by its different location of the 

 varix before the aperture and the less pronounced angulation of 

 the whorls. '

For Aldrich' s original description. — {Loc.cit.) 



As observed in my article published in the Proceedings of the 

 Academy of Natural Sciences of Philadelphia, "this is the most 

 perftcfl specimen of this species yet found." Its apex is some- 

 what eroded and might be represented a little more acute. 

 Strangely enough, it does not show varices on the w^horls, as is 

 usual in specimens of this species.
