A slide with a single example of a Glyphodiscus species (I think probably G. bipunctatus based on available images to compare it with) from Forrester’s Hill 91B, Oamaru, New Zealand. Described as ‘6 processes’, but there looks to be a 7th small one to the left of the one at the 12 o’clock position, and even the start of an 8th, just above the one at the 10 o’clock position. No name for the mounter, however it looks very similar handwriting and style to ones by Richard Gosden. Olympus BHB microscope using 450nm LED light. 63x Leitz Pl Apo NA 1.40 objective, oil immersion.Olympus Aplanat Achromat condenser, oil immersion, oblique lighting. 2.5x Nikon CF PL photoeyepiece. Monochrome converted Nikon d850 camera. 32 images stacked in Zerene (Pmax).
