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: Population of N. minima in co-ocurrence with small Naviculas that could be related to N minima and called N. sp. cf minima. Navicula sp. 1? is not well preserved and hence difficult to identify Nitzschia sp. is girdle view, possibly palea debilis or archibaldii.. Only half of Nitzschia gracilis is preserved Cymbella sp. 1? Large form at the field periphery. N. cryptocephala some valves difficult to distinguish, could be something else as well Navicula sp. 1 NLS DME has the shape of N. cryptocephala but coarser and rarer striae. Sellaphora pupula - only central area preserved
