Genus CYLINDRELLA Pfeiffer. 

 CYLINDRELLA VARIEGATA 1 feiffek. 



This species was described by Pfeiffer before C. lactaria 

 Gould was published. Their identity is well established. 

 I have not received any specimens of the true variegata 

 from Florida, or any other portions of the United States. 

 Pfeiflfer (Mai. Blatt. i. 211) gives Florida as its habitat, 

 probably on the authority of Gould's description in the 

 Terrestrial Mollusks. At that time the figure had not 

 been published. 



Specimens of lactaria Gould, received from himself and 

 also from Poey, agree perfectly with the text (p. 309), but 

 are not the shell figured (pi. 69, fig. 2). Neither do they 

 agree with the Florida shell. Having sent specimens of 

 the shell found in Florida to Poey, he returned them 

 labelled C. Poeyana Orb., and sent me Cuban specimens 

 of the same species. 



It follows, therefore, that the shell figured (pi. 69, fig. 2) 

 is not described in the text, where reference is erroneously 

 made to it under C. lactaria Gould, which is C. variegata 

 Pfr. It will be noticed that no reference to geographical 

 distribution is made by Gould. The shell figured is de- 

 scribed in the following article.
