Remarks: Lateral face, hemispherical shell, with ripples throughout the shell, presence of invaginated buccal tube and string.
Remarks: Lateral face, hemispherical shell, narrower at the basal region, forming a border, invaginated buccal tube and collarette.
Remarks: Lateral face, discoid shell, with invaginated buccal tube. Ventral face, circular shell, circular pseudostoma, invaginated and of large diameter.
Remarks: Lateral face, shell oval and high, with invaginated buccal tube. Ventral face, circular shell with two concentric circles, the outer one corresponds to the junction of the buccal tube with the lateral shell and the inner one is the circular pseudostoma, which may present lobes, and centered.
Remarks: Lateral face, oval shell, with high height and forming depressions, with invaginated buccal tube. Ventral face, circular shell with circular pseudostoma, centered, and collarette at the border.
9B) and another around the buccal tube about one-quarter of the distance down its length (Fig.
This gland, with its duct opening into the mid-region of the newly formed buccal tube, was first resolved in post-larvae at 48 h after onset of metamorphosis.
In the case of Conus, the elongate post-metamorphic buccal tube may have been easier to realize by de novo construction than by remodeling the pre-existing mouth and distal fore-gut of the larva.
