  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: Start x36, y87.9; y102.1; strip 2 x36.7, y87.9; y102.1; strip 3 x37.2, y87.9; y102.1; strip 4 x37.8, y87.9; y102.1; strip 5 x38.2, y87.9; end 95.7. I originally thought some of the fragments here were Surirella species. Now I think they are Campylodiscus hibernicus. Also, the larger Nitzschias look like linearis, but striae and keel punctae measurements fit Nitzschia sigmoidea more precisely. Examples of Navicula pupula were very thin and small -- are they v. mutata?
