Using the compatibility condition for the Painlevé equations, several new fourth-order ordinary differential equations (ODEs) that are analogies of the Painlevé equations are found. The isomonodromic linear problems for these equations are given. Special solutions of the fourth-order ODEs found are discussed. The Painlevé test is applied to investigate several fourth-order ODEs.
