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: R1 x40, y83.8; y91.5. I'm using Hustedt's Navicula tantula for the majority of the small Navicula specimens because of their clear "hourglass" central area. KLB lumps N. tantula w/ N. minima which may be useful in data analysis. I used N. seminuloides for very small, oval Navicula specimens w/o a clear central area.
