Incest differs in species from other sins of lust, because it gravely conflicts with the natural reverence owed to parents, and consequently to persons who are bound to them by proximate conjunction of blood or affinity. - St. Lig., n. 448.
Whether incest with consanguineous persons and incest with affines differ in species, and again whether incest differs in species according to the varied degree of affinity and consanguinity, and therefore whether the degree must necessarily be expressed in confession, we shall say in the Treatise on Penance, where there is question of circumstances aggravating sins.
