THE NAUTILUS. 121 
River, I picked up two specimens of Mytilopsis leucopheata Conr. 
and one Planorbis duryi Wetherby. In many places oyster 
beds are common, and in the Indian River narrows the man- 
grove roots between high and low water mark were completely 
covered with young oysters. 
Three weeks in March, 1892, was spent at Lake Worth, the 
most beautiful place on the Florida coast, with the Gulf stream 
close to the shore. Much of my time was spent in looking at 
the living forms of everything found below low water in the 
inlet, and a collection of many objects was made. I had no 
special collecting outfit, so the small and minute forms were 
practically left out. The inlet of Lake Worth was at that time 
a lonely place, only occasionally a sail boat passed in and out, 
and at low tide I could wade across. -At the time of my visit 
to Lake Worth two residents at Palm Beach had small collec- 
tions, Mrs. Nelsson and her children collected after storms and 
had some shells that I did not see and claimed they were the 
only specimens found by any collector at Palm Beach proper. 
Mr. J. J. White at the time a resident of Palm Beach had a 
small collection of named shells collected mostly at Lake Worth. 
Mr. White published two articles in THe Navtiuus, Vol. XI, 
page 31 and Vol. XII, page 142, about the specimens collected 
by him and his description of the locality is good.
