Original description: Shell spiny, spindle-shaped, with three annular septa. Length of the four joints = 3: 4: 5: 6. The third joint is the broadest, being twice as broad as the constricted mouth. Pores irregular, roundish. Cephalis conical, armed with a bunch of strong, conical spines, and distinguished by double-contoured pores. Peristome with six (sometimes five or seven) triangular, vertical, parallel, or slightly divergent feet.
Remarks on original description: Haeckel listed Cyrtophormis armata under the subgeneric name Cyrtophormium, but did not include the subgeneric name in the species name.[comment from RadWorld database]
