Br Bone's Arrangement of Fossil Orgmik Remains., 143: 
names to designate a single object ; for example, Grypwa- acu- 
leata^ Sclotb. is Producius aculeatus^ Sow. ; GrypJiwa columba, 
Bgt. is GrypJiwa spirata^ Schloth. ; as well as Grypliwa ratisba- 
nensis of the same author ; Gryphoea cymUuwiy Schloth. is Gry« 
pJiwa arcuaia, Lam. This confusion has_ done much to retard 
the progress of geology in reference to the secondary formations^ 
and has contributed so long to delay the acknowledgment of 
identity between the zechstein of Germany and the magnesian 
limestone of England, of the existence of greensand and chalk 
in Germany, the absence of muschelkalk in England, &c. 
Brongniarfs visit to Baron von Schlotheim may perhaps hasten 
the gratification of our wishes in regard to this subject.
