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: all counts start to the left of the scribed line (apparent right on my scope) start 103.0 x 21.1 end 103.0 x 18.0 Nitz. romana: more robust than N. fonticola, finer striae, ends more knob-like Nav. pseudorheinhardtii: from P&R (drawing is out of scale with others on page, I compared the specimen from the collection and I think it fits)), similar to N. radiosa v tenella, but generally broader and more lineate striae. Nav. sp. 1 ANS MT: similar look and shape to N. crypto v veneta, but much larger- perhaps compare to N. menisculus v. upsaliensis??
