Out of these fourteen manvantara-avataras, Yajna and Vamana are also lila-avataras. These fourteen manvantara-avataras are also known as vaibhava-avataras.
In SB 3.11.27 and 4.24.42 p. manvantara-avataras are confused with Manus as seen also from SB 1.3.5 p. Yajna is the manvantara-avatara in Svayambhuva Manu's reign, Vibhu is the manvantara-avatara in Svarocisa Manu's reign, and so on as per SB 8.13, CC 2.20.246 p., 2.20.319.
