One-side head–tail (OHT) galaxies are radio galaxies with a peculiar shape. They usually appear in galaxy clusters, but they have never been cataloged systematically. We design an automatic procedure to search for them in the Faint Images of the Radio Sky at Twenty-Centimeters source catalog and compile a sample with 115 HT candidates. After cross-checking with the Sloan Digital Sky Survey photometric data and catalogs of galaxy clusters, we find that 69 of them are possible OHT galaxies. Most of them are close to the center of galaxy clusters. The lengths of their tails do not correlate with the projection distance to the center of the nearest galaxy clusters, but show weak anticorrelation with the cluster richness, and are inversely proportional to the radial velocity differences between clusters and host galaxies. Our catalog provides a unique sample to study this special type of radio galaxies.

一侧头尾（OHT）星系是具有特殊形状的射电星系。它们通常出现在星系团中，但从未被系统地编目过。我们设计了一个自动程序来在 20 厘米源目录的无线电天空的微弱图像中搜索它们，并编译一个包含 115 个 HT 候选者的样本。在与斯隆数字巡天的光度数据和星系团目录进行交叉核对后，我们发现其中 69 个可能是 OHT 星系。它们中的大多数都靠近星系团的中心。它们的尾部长度与距最近星系团中心的投影距离无关，但与星系团丰富度呈弱反相关，与星系团与宿主星系的径向速度差异成反比。
