TERTIARY FAUNA OF FLORIDA 



from the Oligocene lignitiferous shales of Coos Bay, Oregon, is still unfigured, 

 and in the absence of typical specimens can hardly be recognized, but appears 

 from the description to belong in this section. L. permacra Conrad (Pacific 

 R. R. Rep., vii., part i., p. 192, pi. vii., fig. 4, 1857) and L. tetrica Conrad (Proc. 

 Acad. Nat. Sci. Phila., viii., p. 314, 1856, unfigured) are from the Miocene of 

 California, very likely are synonyms of P. acutilineatus Conrad, but in the 

 absence of types, figures, or sufficient descriptions may be dismissed as unrecog- 

 nizable, though not improbably belonging in this section.

Miocene of Maryland at Calvert Cliffs, Plum Point, and in Charles County ; 

 of the eastern shore of Virginia and at Suffolk, Virginia ; of the Ashley River 

 beds of South Carolina, and of Florida at Alum Bluff on the Chattahoochee 

 River; Burns. The variety subplanatus at Plum Point and Calvert Cliffs, 

 Maryland; Harris. 



This is very near to but differs sufficiently from the recent P. filosus Stimp- 

 son, of the Atlantic coast fauna ; but from the recent and Pliocene Pacific coast 

 form, P. annulatus Reeve, it can hardly be separated. The P. subplanatus is 

 only a local mutation with closer and more delicate sculpture, and hardly de- 

 serves a varietal name.
