**Abstract:** In this paper, we study the oscillation of second-order neutral differential equations with delayed arguments. Some new oscillatory criteria are obtained by a Riccati transformation. To illustrate the importance of the results, one example is also given.

**Keywords:** oscillatory solutions; nonoscillatory solutions; second-order; neutral differential equations
