Original Description Shell ovate, with six to eight slight strictures, twice as long as broad. The three or four upper joints are perfectly separated by annular septa, the three or four lower joints connected by an internal spiral septum. The spiral line is often more or less irregular or interrupted (as is also the case in the specimen figured). Mouth rather wide. Pores small, subregular, circular. A rather variable species. Size: Length of the shell (with eight joints) 0.2, breadth 0.1. Editors' Notes Haeckel listed Spirocyrtis merospira under the subgeneric name Spirocyrtoma, but did not include the subgeneric name in the species name.[comment from RadWorld database]
