SHELLS OF LAKE WORTH, FLORIDA.

Having had occasion to visit the soldiers stationed at Miami, in July 
last, [ could not let such an opportunity pass without profiting by 
it. Heavy rains kept me within doors the greater part of the time. 
When dry enough I was out in the woods skirting the town and was 
amply repaid by finding large quantities of the beautiful Liguus fas- 
ciatus Brug. These I found on trees, sometimes as high as twenty 
feet from the ground. I had to procure a long pole to detach them 
from trees, catching them in my hands, so as to prevent them from 
breaking by falling on the rocks and roots of trees. I soon found that 
I must have a safer way to collect them; so I made a little basket of 
twigs and bark, and attached it to the end of my pole, and found it to 
work admirably. I soon collected all I thought I would need. While 
sitting in the car, waiting for the train to start for Palm Beach, I 
counted twenty-seven on the trees close by the station. 
During my stay of five weeks at Palm Beach and Lake Worth I 
made a number of trips up to the new and old Lake Worth inlets, 
which have been my favorite collecting grounds in years past. Finer 
collecting grounds would be difficult to find on the Atlaniic coast, and 
those who visit them always come away well repaid. Lake Worth is 
about the northern limit for the Strombus, except S. pugilis, which is 
sometimes found further northward. While stopping with W. K. 
Spencer, of Lake Worth, he helped me make a water glass, which was 
a great help in collecting. We took a small butter tub, and, after 
taking out the bottom, we cut a sheet of window glass to fit in its place
