Catalog entries: Siphonosphaera polysiphonia

Original description: Shell a regular or subregular sphere, bearing twelve to sixteen circular pores in its half meridian. Nearly one half the pores simple, very small; the other half prolonged into short cylindrical tubules, half as long as broad, two to four times as broad as the pores and their intervals. This species is nearly related to the foregoing, which it represents in the western tropical part of the Atlantic, but differs constantly in the double size of the shell and the much larger number of the tubules.

Diameter of the shell 0.06 to 0.09, of the pores 0.002 to 0.004, of the tubules 0.01 to 0-.012; their length 0.006 to 0.008, surface.
Remarks on original description: Haeckel listed Siphonosphaera polysiphonia under the subgeneric name Merosiphonia, but did not include the subgeneric name in the species name.

"...the foregoing..." refers to S. socialis Haeckel, 1887a
