因明入正理論疏 3.204

3.204

述曰：下第四大段，明二似量。真似相形，故次明也。於中有二：初似現、後似比。似現之中復分為二：初標、後釋。此即初也。

The commentary says: The fourth major section below explains the two pseudo-pramāṇas. Genuine and pseudo are contrasted with each other, hence it is explained next. Within this there are two parts: first, pseudo-perception; second, pseudo-inference. Pseudo-perception is further divided into two: first, setting forth [the definition]; second, explaining it. This is the first.
