* Some few years ago, Eepton Park Poiid burst, when, in addition 

 to the Unios and Anodons above given, several specimens were taken 

 which scai'cely come under the head of named varieties. It may also 

 be furtlier noted that several years ago a remarkable variety, which in 

 "Brown's Conchology " is named Anodonta confo7-t'i., was found by a 

 gentleman named Grlover in some ditches near to the Old Trent, but 

 this shell has not since been found.
