VARIATION AND ZOOGEOGRAPHY OF LIGUUS IN FLORIDA. 4$9 



Old Rhodes Key. At the north end biguus was found. The living specimens 

 are much smaller than many of the dead shells on the ground. The adjacent 

 Reid's and Rubicon Keys are mangrove keys, hence without Liquu*. 



Totten's Key. Liguus living. 



Porgy Key. Snails (Liguus) which began crawling in the rain of two da} 

 ago were mostly high in the trees here. Shells very frail. Many broke in falling. 



Meiggs Key. Small, but with suitable vegetation. No living snails found, 

 nor were any shells seen on the ground. 



Caesar's Rock, a small key with a little high ground. No sign of tree snails. 



Adams Key. Large Liguus here and there on the ground, but only one 

 live snail found in a search made by four persons. 



Elliott's Key. A small pale form of Liguus was taken near the south end. 

 No large ones were found, either alive or on the ground. A native of the key 

 told us that snails of other colors are found there." 



Cape Florida, south end of Key Biscayne. The hammock has been clean .1 

 here recently and no vegetation suitable for Liguus was found by us. No live 

 snails were met with, but small snail shells were abundant on the ground. A 



Single Liguus of the Miami type was given us by the owner of the place, who said 



it came from there; but he may have been mistaken. On the remainder of Key 

 Biscayne only mangrove is said to grow. No hammock land waf visible from 



our boat. 



No entirely trustworthy evidence of the existence of Liguus Dn the outer 



line of keys above Elliott's Key was obtained. That key is probably its northern 



outside limit. 



The Arsenicker Keys— small inside keys near the mainland— are mangrove 



keys without suitable vegetation for Liguus. 



Mainland of the East Coast, Dade Co. 



Cutler, Dade Co. Liguus abundant. The winter of 1903-4 has been I he dry- 



est season in years, but during our visit there was rain. The Liguus appewed 



on every side, many were on bushes or piles of brush, as if they had been hidden 



in damp places on the ground. The shells marked with brown are chiefly found 



in the thick woods. . ^, 



Miami, at the mouth of the Miami River. Liguus is abundant in the woooi 

 on the south side of the river, opposite the town. Also on the north side of the 



well 



about 2V 2 miles west. ' Opposite this place it occurs on the south sid 



At the House of Refuge, on the outside near the head of Biscayne Bay, no 

 suitable hammock land exists, and Liguus is not found. 



At Natural Bridge, on Arch Creek, about 9 miles north of Miami, biguv* waf 

 found to be scarce, only four living ones found, though the hammock is extensn i 



and apparently favorable
