Mr. Martens (then assistant geologist of the Florida Geological 

 Survey) was at the locality while the shovel was working, and the 

 section described by him, with a slight rearrangement, is as follows : 



Feet 



3. Unconsolidated sand 2 



2. Hard yellow limestone, containing many Chione cancellata 3 



1. Unconsolidated medium-coarse sand with numerous shells ; 



above water 1 



Mr. Martens observed that only 1 foot of the lower bed was above 

 water, but understood that the shovel was taking similar material at 

 a depth of 6 feet below water level. 



All the species listed in this paper are believed to have come from 

 this lowest bed, ranging in a vertical distance from 5 to 12 feet below 

 the surface. The following table gives the species collected, with 

 their relative occurrence and geologic ranges :
