CRITICAL NOTES ON THE BULIMULI OF FLORIDA. 



BY BERLIN H. WRIGHT, LAKE HELEN, FLA. 



Bulimulus Dormani W. G. B. var albida Wright. 



That this is a good variety would appear from the following facts : 

 It is never found associated with the typical. I have seen trees liter- 

 ally loaded with the typical B. Dormani, where it would have 

 been possible to have secured thousands of specimens in a few hours 

 time and have taken as many as five hundred in a day, but never 

 have been able to discover any tendency to change of any of the 

 characters. At one time I had over one i/iousojirf living, full grown 

 specimens spread out in a large box and with the closest scrutiny 

 no freaks were seen. We liberated nearly all of them subsequently. 



In a dense hammock well isolated from any similar lands and 

 fully a dozen miles from any locality where the typical B. Dormani 

 is to be found, the pure white shell occurs. It is not plentiful, but 

 always sjjotless. In form it does not seem to differ from the typical. 

 Bulimulus Hemphilli Wright. 



In the hammock lands located upon tlie narrow strip of land lying 

 between Mosquito Lagoon and the Atlantic Ocean, there is another 

 form of Bulimulus found. This is shorter, its whorls more rounded 

 and is thinner tlian B. Dormani. This shell was discovered by 

 Mr. Henry Hemphill of San Diego, Cal. in 1884 and Dr. Biuney, 

 judging from the few dead specimens in hand, pronounced it a var. 

 of B. Floridanus Pfr. Subsequently I found a fair number of liv- 

 ing specimens and became convinced that it was a good species and
