Radial velocities for the hydrogen, Si II, and Ca II lines of HD 184905 are given, and it is found that the period that best represents the data is 2.1701 days. The major line anomalies in the spectrum of the star are discussed, and it is concluded that Si, Sr, and Eu are the major anomalies, with all three species exhibiting strong line-strength variations.
