), arching over the basal foramina, when the hydrothecae are seen laterally. These structures, one situated in the “frontal” aspect of the hydrothecae, the other on their “dorsal” side, correspond in fact to the attachment points of the hydrothecal bases to the lateral walls of the thecae which, in this species, are raised above the level of the foramina. When the hydrothecae are seen facing their apertures, the hydrothecal bases appear U-shaped, the foramina being situated at the bottom of this concavity.
