some interest to conchologists. The writer, Chas. T. Simpson, 

 claims that even in land shells of the same species the color is not 

 always persistent. It may be remembered that in a paper pub- 

 lished some years ago in- the Proceedings of the Association the 

 claim that the color of sea shells was owing solely to light was dis- 

 puted at a time when the statement was generally accepted. " While 

 living at Braidentown, Florida, I found Bulhnidus Dormani quite 

 abundant, living and dead, in heavy lands north of Manatee River, 

 and with the typical form on the very same trees I found quite a 

 number of specimens without a vestige of color. The ground of 

 most of these shells was a lovely pale porcelain, the spots were 

 reddish brown, sometimes forming uninterrupted bands, clouded, 

 and more or less distant." 



Detached remarks like the above are rarely published in our 

 proceedings. They may be, perhaps, incorporated as Notes. The 

 foregoing is of considerable interest to concologists, more especially 

 collectors of land and fresh water shells.
