  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: row1 71.1x96.8 end 112.5= 15.7mm Na.gregaria centered row2 72.3x96.5 end 112.5=16.0mm Na.gregaria touch rt margin row3 73.5x96.8 end 112.5= 15.7mm Na.capitatoradiata centered row4 74.8x96.9 end 112.5= 15.6mm Na.canalis centered row5 76.1x96.5 end 112.5= 16.0mm Cocc.pediculus centered five full rows counted. Possibly two types of Nav. canalis present one typical, one smaller and finer striae similar to Na.vandamii v. mertensiae. Very difficult to separate.
