Original Description

Shell a regular or subregular sphere, with numerous very small pores of equal size and distribution, ten to twelve in its half meridian. Bars between the pores four to six times their diameter. Only a small number (two to six) of very large funnel-like tubules, irregularly scattered. The inner half of these tubules is a short cylindrical tube, of the same thickness as the shell, three to four times as broad as the pores; the outer half is an irregular funnel, suddenly expanded, with siliceous walls of the utmost tenuity and fragility, often irregularly folded and contorted, like a decayed flower-calyx, often half as large as the shell.

Diameter of the shell 0.1 to 0.12, of the pores 0.003 to 0.005, inner half of the tubules 0.015 to 0.02, outer funnel-like half 0.05 to 0.08. [dimensions in mm]

Editors' Notes
Haeckel listed Siphonosphaera chonophora under the subgeneric name Merosiphonia, but did not include the subgeneric name in the species name.

Figure description: "fig.4" refers to Siphonosphaera tubulosa (Muller) in Haeckel 1887a; "fig.7" refers to Siphonosphaera patinaria Haeckel, 1887a
