Dimensions: Alt., 68; lat., 49; aperture, 44x30. 



This species was found only in the clay shales near Gettysburg, 

 Wash., by the writer. Mr. Arnold, however, found it represented 

 in the sandstone that overlies these shales.

The specimen obtained is much crushed longitudinally. It is a 

 small shell and resembles the immature specimens of Dolium pe- 

 trosum Con., but unlike them it has two revolving rows of large 

 nodes on the body whorl; the ribs are also more elevated and more 

 angular.

The impressions of the stems of seaweed, doubtfully referred to 

 the above genus, are often met with in the rocks of the Clallam 

 formation, especially in the shale-bearing regions. They resemble 

 the long, pipe-like tubes of the kelp so abundant in the strait adja- 

 cent at the present time.
