四分律行事鈔資持記 2.511

2.511

釋第三中，初文。不能男女，即二種黃門；或彼此互是，或二俱是，竝同下犯。下列二女，道合一道是一種（舊分二女，非也。）；石女者，根不通涶者，羯磨列遮云：二道合、道小，即同此矣。

In explaining the third, the first text: "incapable males and females" refers to the two kinds of paṇḍakas; whether one or the other is such, or both are such, they are all equally the lower offenses. Below, two [types of] women are listed: having the paths joined into a single path is one type (the old division into two women is incorrect); the "barren woman" (*śoṇḍhī*) whose organ does not admit saliva—in the karmavācanā listing the impediments, it says "the two paths joined" and "the path being small," which is the same as this.
