x: C. elegansOriginal description: Very elegant representative of the genus, with 4 lattice ellipsoidal shells. Longitudinal axis of the internal ellipsoid: 20µm, of the second shell: 55µm, of the third shell 140µm, of the cortical shell 160µm. Small axis of the cortical shell 150µm. The ellipsoid shell is, thus, slightly elongated. Polar spines round, smooth, without sides, of a length of 60µm, and with a basis as broad as 12µm. Third shell robust, with regularly distributed pores of 9-10µm diameter, shaped as 6-sided funnels. On the sides of the funnels there are small delicate spines that give at a distance of 15µm some tangential apophyses that are anastomosed in a fine superficial network shaped as a spider web.
