of ejecta from Langmuir partly covers the southeast interior floor of Chebyshev. This crater has not been heavily eroded, and many of its original features remain intact and sharply defined. The rim to the west is somewhat disrupted due to having overlaid the rim of the larger Chebyshev. In a coincidental arrangement, a small crater is situated across the rim edge at the northern end of where it joins with Chebyshev, and a smaller crater lies at the southern end of this merger. The inner wall of Langmuir contains some minor

structures and displays some appearance of slumping along the southwestern edge. The inner wall in the southern half of the crater is wider than elsewhere, and is nearly twice as wide as the inner wall along the northern edge. As a result, the interior floor is offset to the north. There is a central peak formation on the floor, but it is located to the northeast of the midpoint. The floor is relatively level in the western half, but more uneven in the east.
