466 VARIATION AND ZOOGEOGRAPHY OF LIGUUS IN FLORIDA 



31 North of Naples, on Pine Island and on keys to the north and west of p 

 Island careful inquiry has failed to locate any trace of Liguus, past or present 

 Reports of the presence of tree snails on Gasparilla Island, which is north of 

 Pine Island, and on Sanibel Island, probably emanated from persons who 

 fused Liguus with Glandina or with the snails found on the mangrove trees 

 IAttorina, [The large Littorina angulifera often ascends six to ten feet or more 

 and is common on mangrove trees, piles, etc., all along the coast.] 



At the present time (1904), it is believed that no Liguus is to be found at 

 Little Marco. It was abundant at Marco, Key Marco, in former years, accord- 

 ing to residents of Marco, but is not now to be found there. Search made on a 

 nameless key which has good hammock vegetation, three miles east of Marco 

 settlement, by Mr. Addison, the owner of the key, and living on it, failed to 

 discover any trace of Liguus. 



The northernmost habitat of Liguus on the west coast of Florida at the present 

 time (1904) is believed to be Goodland Point, Island of Marco. This place is 

 five miles south of Marco, which is a settlement at the northern end of the island 



of Marco. 



Marco Island is the largest key of the Ten Thousand Islands, a region of 



islands ("keys") with open water here and there, beginning at Naples, about 

 nine miles in a straight line north of the Island of Marco, and extending to the 

 Northwest Cape, which is the upper end of Cape Sable. 



Mr. Pettit, of Goodland Point, says Liguus is rapidly disappearing from 

 Goodland Point (1906). A few were found by us there and no doubt more 

 would be seen after rain. The women of the Pettit family now make baskets 

 with snails arranged as pendants, each basket requiring thirty or forty snails. 

 They have had snails brought from Miami and were offering to sell the shells, 

 which were mixed with others from Goodland Point. The person who intro- 

 duced this feature was not at the place when I procured the shells there two 



years ago 

 Marco 



Liguus was found by us also at Caximbas, the southern end of Key 



Horr's Island, south of Key Marco, at "Blue Hill," a hammock tract 



No 



snails were found on the trees in 1904, though dead ones were on the grouna. 

 February 14, 1907, a long search revealed a few living Liguus. 



At Gomez's Old Place (a key), Liguus is fairly abundant 



At Cape Romano, Four Brothers Key, Dismal Key and Gomez Point . 

 House, who made a search for me, found no trace of Liguus. 



Buttonwood Key, Lee County. But little suitable growth ^at tins p 

 No Liguus seen on the trees or their shells on the ground in 190b. ^ ^ 



Dismal Key, Lee County. Our agent was unable to find Liguus i ^ ^ 

 summer of 1904. There is ample vegetation of a suitable cnaract ~' d An0 id 

 visit (March, 1906) we saw no sign of Liguus on trees or onth ®^ in the past 

 woman and a little child live on this key. The old woman said tnai ^ 



she had seen tree snails on the key and described the coloring, snowing 

 confound Liguus with the mangrove snails.
