Catalog entries: Siphonosphaera patinaria
Original description: Shell a regular or subregular sphere, occupied by numerous broad cup-like tubules of very different sizes. In the half meridian of the shell about six to eight tubules, very flat, circular or subcircular, much constricted in the middle. Diameter of the inner aperture larger than that of the middle stricture, smaller than that of the outer aperture of the tubule; outer diameter two to four times as great as their length.
Remarks on original description: Haeckel listed Siphonosphaera patinaria under the subgeneric name Holosiphonia, but did not include the subgeneric name in the species name.[comment from RadWorld database]
