Which item listed is not considered a type of motion in parliamentary procedure?

In parliamentary procedure, motions are formal proposals put forward for discussion and decision. The correct choice, which is not considered a type of motion, is "debate motions." While parliamentary procedure allows for debate on motions that have been presented, the terminology does not specifically categorize "debate motions" as a distinct type.

The other types, including subsidiary motions, incidental motions, and privileged motions, all serve specific purposes within the process.

Subsidiary motions are used to modify or affect the main motion being considered. Incidental motions arise out of the business being conducted and are related to the procedure of the meeting itself. Privileged motions relate to the rights and privileges of the assembly, taking precedence over other motions. Each of these categories has defined functions within the rules of parliamentary procedure, unlike the concept of "debate motions," which refers more to the process of discussion than to a distinct category of motion.
