Citrus Tree Snail 



An arboreal snail, Drymaeus dormanl (Binney), was first reported In 

 citrus groves in Florida by Sellards (1906). D. dormanl has cormionly 

 been called "Manatee snail" (Simpson, 1893; Sellards, 1096; Dailey, 

 1975), "Tree snail" (Sellards, 1906; Norris, 1955), "Citrus tree snail" 

 (Kramer, 1952), and "Bob Norris snail" (Lawrence, 1950). 



L. J. Dorman first collected the snail near St. Augustine, Florida, 

 and Binney (1857) described the species as Bulimulus dormanl Binney, in 

 honor of Dorman. B^. dormanl was found to be closely related to B^. 

 masculatus and B^. floridanis of New Grenada (Binney, 1859; Binney and 

 Bland, 1869). 



The genus was changed to Liostracus dormanl (Tryon, 1882). Pilsbry 

 (1899) assigned the citrus tree snail to Its present genus. 



The current hierarchical classification of D. dormanl is as follows: 



Kingdom - Animal 



Phylum - Mollusca 



Class - Gastropoda 



Subclass - Pulmonata (air breathers) 



Order - Styloninatophora (terrestrial) 



Family - Bulimulidae 



The range of the snail is limited in the U.S.A. to Florida (Grif- 

 fiths, 1949). Pilsbry (1946) stated that D. dormanl was "an
