type image: L. quadrangulaOriginal description: Cortical shell with thorny surface, three times as long as the lentelliptical medullary shell. Perimeter of the lateral plane nearly quadrangular, with four rounded corners (on the poles of two crossed diagonal axes), one and a third times as long as broad, with one sagittal constriction at the poles of the principal axis. One lateral wing of the transverse girdle turns around the other in one and a half to two simple spiral turns.
Remarks on original description: Haeckel listed Larcospira quadrangula under the subgeneric name Larcospirema, but did not include the subgeneric name in the species name.[comment from RadWorld database]
