468 VARIATION AND ZOOGEOGRAPHY OF LIGUUS IN FLORIDA. 



They are of a thin, white type, unlike any other West Florida lot [var. loss- 

 manicus]. Subsequently we found several colonies. 



This ends the Ten Thousand Islands. On the mainland at Cape Sable 

 Middle Cape, shells of IAguus were abundant on the ground, but living snails 

 were rare on the trees. Mr. J. L. Watrous informed us that ten days before 

 he had seen them abundantly. At East Cape the snails were found in con- 

 siderable numbers here and there. 



At Flamingo, still further eastward on the mainland, Oxystyla was found, but 

 no IAguus. Neither occurred on Murray's Key, opposite Flamingo, about three 



miles out. 



Sandy Key, to the south, has Oxystyla but no IAguus. 



East of Flamingo, Monroe Co., no collecting was done by us on the mainland 

 until we reached Cutler, on Biscayne Bay, Dade Co. The south coast of Dade Co. 

 is said to be a mangrove shore. [Hammock land suitable for IAguus exists inland, 

 colonies of Liguus being known from Homestead and Detroit.] 



From Key Vaca northeastward the following keys have been investigated: 



Lignum Vitse Key. IAguus and Drymams found. 



Indian Key. Brush cleared off— no snails. 



Lower Matecumbe Key, east end. The Liguus here were not sealed to the 



bark as at places visited heretofore. 



West end Upper Matecumbe Key. Liguus scarce— a few met with. 



Tea Table, a small key with unsuitable growth for snails— none found. 



Windly's I, or Umbrella Key. Liguus found at the east end. 



Long Island, or Plantation Key, west end. Liguus found. 



Tavernier Key, a mangrove key unfit for snails. . 



Key Largo. In a hammock two miles east of the town of Planter Liguus^ wa 

 found, chiefly high in the trees. On Dove Key, opposite this place here is no 

 suitable vegetation. At Point Charles, Key Largo, Liguus was mo tly high on 

 trees and very firmly fastened. In a clearing where bushes were not high a lew 

 snails were found, large but paler than the rest as a rule, as i ■ ^ ^ ™ ^ 

 bleaching effect. I found at this place two snails of the kind found ^ at PavUm 

 Key and Seminole Point (Oxystyla floridensis) . Near the north end of Key Larg 



Liguus was also collected. . , . 



Pumpkin Key, inside the upper end of Key Largo. Liguus ; active ^ 



Angel-Fish Key. Snails very scarce; only two found alive.
