WHITE BEACH, LITTLE SARASOTA BAY. 



This formation is at the water's edge, near the northern end of the bay, 

 and is partly covered at high water. It is a coarse, calcareous rock, in which 

 the shells are represented by molds in the rock or by calcareous pseudomorphs 

 which have filled these molds after the latter had been more or less distorted, 

 and from which the surrounding limerock has been weathered away after 

 the formation of the pseudomorph. The body of the rock contains nothing 

 but molds ; the surface, when subject to percolation, alone exhibits the pseudo- 

 morphs. The original rock seems to have been a coquina without any silicious 

 sand in it, which became a yellowish limestone which was then somewhat 

 crushed and near the surface infiltrated. There are traces of an unusual quan- 

 tity of polyzoa, corallines, wormtubes, etc., which seem to have grown over
