Count Notes:

  ?
  Comments: This sample has been concentrated 4 times more than normal and maximum amount has been applied on the cover slide. Still only 62 valves per transect (100 x objective) were present on the slide. In total only 250 valves have been counted in four transects.
 
Taxa Notes:
 
Naded 37007: Axial area narrows towards distal ends. Image taken.
Naded 67004: Tabellaria quadriseptata has max 5 bands. Tablellaria floccculosa has many more bands. This is a difficult not yet resolved complex. T. flocculosa has normally a wider central area compared to the capita. The found diatom has a high number of bands but the captita are wider compared to the central area. Spines are present. Image was taken.
