1 QUALIFIER:

  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= 95.5; y= 8-13. Chain of 17 valves of Fragilaria in girdle view was identified as Fragilaria neoproducta. No valve view of this species was found anywhere in the count, therefore identifcation was based on striae count 16/10 microns, which would not fit Staurosirella pinnata (S. pinnata = 6-12/10). This colony is located in final circle at 95.5 and 13. Slide counted was concentration "h" and not "l" as accidentally entered in the database. Could not correct this in the database afterwords!
