  Qualifier Code: TaxaNote
  Description: Notes taken about the taxa for a count; older data typically includes information such as beginning and end scan coordinates, unusual taxa, etc.
  Comments: Row 1 x 43, y 86.5; y 102; Row 2 x 41, y 102; y 87; Row 3 x 40, y 87; y 102; Row 4 x 38, y 102; y 87; Row 5 x 36; y 87; y 95. 100 valves counted after a 1 hour analysis. hence a full count of 600 valves can not be reached within the four hours required for the analysis. Counted valves in good condition. Only a few pieces and dissolved valves. Additional scanning of the slide did not yield new taxa.
