Slide contains numerous smaller cells of Nav. circumtexta
Slide was counted twice, I was not satisfied with the ID in the first count esp the Navicula cryptocephala types which appear diverse; Marina P. looked at these for me and suggested the Nav. crypo veneta var 1 & 2 . The lineolae appear coarser than noted in the literature for these Naviculas.
