C, Ventral view showing the transverse cirri, each of which separated into two or three parts (arrowheads). D, E, Ventral (D) and dorsal (E) view, showing the anterior and posterior portion of adoral zone of membranelles and the five transverse cirri. Note the split occurs in the cilia of cirri while the bases are ordinary. AZM1, adoral zone of membranelles 1; AZM2, adoral zone of membranelles 2; DK1
