  We explore some properties of wide subcategories of the category
mod$\,(\Lambda)$ of finitely generated left $\Lambda$-modules, for some artin
algebra $\Lambda.$ In particular we look at wide finitely generated
subcategories and give a connection with the class of standard modules and
standardly stratified algebras. Furthermore, for a wide class $\mathcal{X}$ in
mod$\,(\Lambda),$ we give necessary and sufficient conditions to see that
$\mathcal{X}=\mathrm{pres}\,(P),$ for some projective $\Lambda$-module $P;$ and
finally, a connection with ring epimorphisms is given.
