Hermanella mazama c: Chorionic surface smooth and general shape prismatic of the egg with concave and convex (arrowhead) polar region. d: Knob-terminated coiled threads (arrow) restricted to the concave polar region. Hydromastodon sallesi e: General shape, with knob-terminated coiled threads (arrows) distributed ring-like in the middle egg region and regularly distributed on the concave polar region. Hydrosmilodon gilliesae f: General shape of egg with knob-terminated coiled threads (arrow) regularly distributed on the surface. Scale bars: 10 µm.
