Abstract: If a closed, irreducible, orientable $ 3$-manifold $ M$ does not possess any $ 2$-sided incompressible surfaces, then it can be very useful to investigate embedded one-sided surfaces in $ M$ of minimal genus. In this paper such $ 3$-manifolds $ M$ are studied which admit embeddings of the nonorientable surface $ K$ of genus $ 3$. We prove that a $ 3$-manifold $ M$ of the above type has at most $ 3$ different isotopy classes of embeddings of $ K$ representing a fixed element of $ {H_2}(M,\,{Z_2})$. If $ M$ is either a binary octahedral space, an appropriate lens space or Seifert manifold, or if $ M$ has a particular type of fibered knot, then it is shown that the embedding of $ K$ in $ M$ realizing a specific homology class is unique up to isotopy.
