THE NAUTILUS. 63 



yet found anything bearing any resemblance to this shell. True, it 

 may exist upon some of the Keys, but diligent inquiry among corre- 

 spondents fails to bring out any information as to its whereabouts. 

 Does any reader of The Nautilus know of any specimen hav- 

 ing been found ? Has any one ever seen it? Is there a specimen in 

 the United States ? If no one has any knowledge of the shell's exist- 

 ence in Florida, is it not time the name was dropped and treated 

 as a lost species ? Many shar]) collectors and students have scoured 

 the wilds of Florida very thoroughly and if it is really here its pres- 

 ence should have been known before this. 



Any one posessing any information upon this matter will confer a 

 great favor by addressing the writer.
