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 6j'(?///zrt', 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 Xididaria 

 stcrcorea has a fimbriate mouth, which is contradicted by his own 

 specimens.
