Let N_{g,s} denote the nonorientable surface of genus g with s boundarycomponents. Recently Paris and Szepietowski obtained an explicit finitepresentation for the mapping class group M(N_{g,s}) of the surface N_{g,s},where s\in{0,1} and g+s>3. Following this work we obtain a finite presentationfor the mapping class group M(N_{g,s}) with generators being Dehn twists andone crosscap slide.
