SEMUN'CIA. A half ounce weight (Liv. xxxiv. 1.); a half ounce measure (Columell. xii. 21. 2.); and a small piece of money containing the twenty-fourth part of an As. Varro, L. L. v. 171.

2. The semuncia is also enumerated by Cato (R. R. x. and xi.) in a list of farming implements and stock, but without any context to suggest a notion of the object intended. Some commentators suppose it to be a small pair of panniers of half the usual size.
