(IAU Directions) BURG.--A noteworthy formation, 28 miles in diameter, on the Mare, N. of Plana. The floor is concave, and includes a very large bright mountain, which occupies a great portion of it. The interior slopes are prominently terraced, and there are several spurs associated with the glacis on the S. and N.W. A distinct cleft runs from the N. side of the formation to the S.W. border of the Lacus Somniorum, which is crossed by another winding cleft running from a crater W. of Plana towards the N.W.
