An arrangement of six Navicula splendida from America. This name is currently regarded as a synonym of Diploneis splendida Cleve.Not sure as to the maker, but the style looks similar to Arthur Charles Cole, so a question mark after the name.

Olympus Aplanat Achromat condenser, oil immersion, oblique lighting. 2.5x Nikon CF PL photoeyepiece. Monochrome converted Nikon d850 camera. 49 images stacked in Zerene (Pmax).
