Catalog entries: Siphonosphaera vesuvius

Original description: Single spherical, rarely elliptical, shell with numerous regularly spaced, fairly uniformly sized and shaped open ended, slightly concave conical tubes. Radial length of tubes generally equal to or slightly greater than diameter of pores at end of tubes. Concave curvature of tubes often merges at base of tubes into convex circular swellings of shell surface. Distance between pore centers typically between 2 and 3 times diameter of pores. Tube length 5%-10% of shell diameter. No spines. Shell surface smooth.
