Original Description Shell conical, gradually dilating towards the wide mouth, similar to the preceding, but differing in the curved axis, and the broader and shorter joints, each of which bears only two or three transverse rows of square pores. The turnings of the staircase are not so sharp, nor so distinct, as in the preceding species. Cephalis with a single short horn. Size: Length of the shell (with eight joints) 0.1; breadth of the fourth joint 0.05, of the eighth joint 0.08. Editors' Notes Haeckel listed Spirocyrtis cornutella under the subgeneric name Spirocyrtidium, but did not include the subgeneric name in the species name. Questionably synonymized with Spirocyrtis scalaris Haeckel by Nigrini, 1977.[comment from RadWorld database]
