mens, which are still in good condition at the Philadelphia Acad- 
emy of Sciences. This appears to be a rare species, as it is known 
only from its original collection. It differs from all the following 
Species of Cyathia, which have a smooth inner surface, in having 
a fimbriate mouth, though Schweinitz in his original description 
notes that it has a smooth mouth, but he writes that Midularia 
stercorea has a fimbriate mouth, which is contradicted by his own 
specimens,
