Abstract
In this paper we show that the Hilbert scheme H(3,g) of locally Cohen- Macaulay curves in P-3 of degree three and genus g is connected. This is achieved by giving a classification of these curves, determining th e irreducible components of H(3,g), and giving certain specializations to show connectedness. As a byproduct, we And that there are curves w hich lie in the closure of each irreducible component.
