If the deceased leaves neither descendants, nor brothers, sisters, or descendants from them, nor parents, nor spouse not judicially separated, nor other ascendants, his other collaterals succeed to his separate property. Among the collateral relations, the nearest in degree excludes all the others. If there are several in the same degree, they take equally and by heads.
