(IAU Directions) CICHUS.--A conspicuous ring-plain, about 20 miles in diameter, with a prominent deep crater about 6 miles across on its W. rim. It is situated on a curious boot-shaped plateau, near the S. end of the rocky mountain barrier associated with the last two formations. Its walls rise about 9,000 feet above a sunken floor, on which there is some faint detail, but apparently nothing deserving the distinction of a central mountain. The plateau on the N. is cut through by a fine broad valley, which has obviously interfered with a large crateriform depression on its southern edge. A cleft runs from a small crater E. of the plateau up to this valley, and extends beyond to the E. wall of Capuanus. There is also a delicate cleft crossing the region S. of Cichus to the group of complicated formations S.E. of Capuanus. As already mentioned, the great Hesiodus cleft is associated with the Cichus plateau.

- Satellite craters Cichus B and C are on the ALPO list of banded craters
- According to T.W. Webb (the author of the classic guide Celestial Objects for Common Telescopes) there was (or still is) a small crater in or near Cichus which "grew larger as compared to the earlier representations of Schroter and Madler".
