Species / Pletzachia Furcata

Stromboidea


Original Diagnosis of Pletzachia furcata by Kollmann, 2009, p. 42:

  • "Shell large, shoulder of last whorl passing into keel of the wing and extending farther into the prominent distal digitation. Proximal digitation very long and narrow, almost parallel to shell axis. Small thorn between digitations."

Original Description of Pletzachia furcata by Kollmann, 2009, p. 42:

  • "The shell is large and high turriculate, the apical angle approximately 30°. The whorls are convex with a narrow sutural neck and a sculpture of strong, prosocline collabral ribs which are rounded on top. A spiral sculpture is not discernable. The last whorl possesses a broad, rounded shoulder. The labral wing is smooth. A strong keel escaping from the margin of the shoulder extends into the distal digitation. The proximal digitation is long, delicate and almost parallel to shell axis. Its posterior angulation is generated on the wing above the angulation. Between these digitations a small but broad thorn is located. The external margin of the labral wing is incomplete in any of the specimens but seems to be broadly rounded. In one specimen (Figure 4.2.) a short rostrum is preserved."
