  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 x36.5 y114.9; y111.5. Dirty slide with many obscured valves and many valves in girdle view. Confusing taxa: N. erifuga, N. hintzii, N. cryptotenella, and N. antonii. N. rostellata and N. germainii were also difficult to distinguish. Also, C. invisitatus, C. tholiformis, S. hantzschii, and S. medius were difficult to separate in a slide with this much sediment.
