 crenulatus Dall, Tr. W. S., 3, p. 1383, pi. 55, f. 12, 1903. 

 Distribution. — Miocene of New Jersey to Florida (upper bed, 



Alum Bluff); and of the Galveston well at 2410-2871 feet 



(Harris). 



Note. — Dr. Hilgard identified a shell from the Lake Borgne 

 borings, La., as this species, but it was probably P. multi- 

 li?ieatus, since P. crenulatus is not later than Miocene.

 Remarks. — The recent shell was described as L. crenella and 

 its Pliocene and Pleistocene ancestor as L. multilineata, 

 but they seem to inter grade. The shell has often been 

 confused with the Miocene crenulatus. Tuomey and
