( Migoccne of the silcx beds at Ballast Point, Tampa Bay ; of the Chipola 

 Rive-rand Oak Grove, Santa Rosa County, Florida, Burn's ; and mixed with 

 Miocene species in the rehandled marl of Jericho, Cumberland County, New 

 Jersey, Burns. 



This species differs from the typical Miocene I\ Goldfnssii Wagner in 

 its smaller six.e, more e(|iiilatcral valves, and less expanded anterior region. 



Panopea Goldfussii Wanner.

 /'. /WvvrAi Conrad, Kos. Medial Tert., p. 71, pi. 41, fig. 2, 1842. 



Miocene of Maryland at Jones's Wharf, Plum Point, Langley's Bluff, St. 

 Mary's, Calvert Cliffs, and on the Choptank River; of Virginia at Suffolk and 

 on the Nansemond River, Nomini Cliffs, and Grove Wharf, Burns and Harris; 

 and in the upper bed at Alum Bluff, Cliattahooehcc River, Florida, Burns. 



This species, though varying like the others, may almost always be 

 distinguished by its expanded anterior end, and elongated and attenuated 

 posterior part. It is very close to the European /'. Rudolf hii Eichwald, /'. 

 liastcroti Valenciennes, and /'. Mcnardi Dcshaycs, which, from the figures, 

 appear to be pretty much one and the same species. The last two are united 

 by Deshaycs himself in manuscripts in my possession, I )esliayes's name being 

 the prior one. 



7'. porrccta Conrad is identical with this species.
