Comments: Row 1 x34, y87; end x34, y93.6. Interesting Achnanthes and Mastogloia specimens. I did not see many A. exilis in valve view. I wonder if it may look similar to A. minutissima v. scotica in girdle view, or if I am only seeing one species. Cymbellas were sometimes difficult. Taxa Notes: None.
