On The Estate of Apollodorus (20)

Thus the law gives the sister and the sister's son an equal share of their father's and their brother's estate; but when a first cousin, or any other kinsman in a remoter degree, dies, it no longer grants such equality, but gives the male relatives the right of succession as next-of-kin in preference to the female. For it declares that “the males and the issue of the males, who are descended from the same stock, shall be preferred, even though their relationship to the deceased is more remote.” The wife of Pronapes, therefore, had no right to claim a share at all, and Thrasybulus ought to have claimed the whole if he regarded my adoption as invalid.
