B, tornotes in vertical arrangement at the subectosomal region. C, tornotes in bouquets at the ectosomal region. C, ectosomal layer of ectosomal acanthostyles. D, detail of the ectosomal layer with ectosomal acanthostyles. E, choanosomal reticulation of choanosomal acanthostyles I equinated by choanosomal acanthostyles II. F, choanosomal acanthostyles I and II echinating a basal plate of spongin, which covers debris. G, tornotes. H, extremities of the tornotes. I, choanosomal acanthostyles I. J, choanosomal acanthostyle II. K, ectosomal acanthostyles. L, anchorate isochelae I. M, anchorate isochelae II. N, sigmas.
