  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 x 105, y 3, y 16. ONly 131 valves counted in an hour of analysis. A full count would not be reached by time limit. Many pieces and partially dissolved valves are present in the sample mixed with medium-sized sediment particles. Continued count: Row 2 x 103, y 16, y 2, Row 3 x 102, y 2, y 17, Row 4 x 101, y 17, y 5. Sparse sample. Full count was reached at 4.25 hours. I invested an extra 15 minutes on this slide becaiuse at four hours I was very close to reaching the 600 vlave count.
