This species is represented in the collection by a lew individuals 



brought from the shores of Lake Sevier, forty miles from Fillmore, Utah, 



by Mr. Gr. K. Gilbert, geologist of the survey. No living shells were found, 



and the probabilities are that the shells collected were washed from the 



Sevier River, which is fresh water, into the briny waters of the lake, and 



there perished. It is rather curious that a shell so common, and with such 



a wide range of distribution, should have been met with in but one locality 



in Utah.
