The blackbuck Antilope cervicapra (Linnaeus) is a grassland antelope widely distributed in Pakistan, Nepal, and India. Here we present a review of the known horn anomaly in the species followed by two new examples: a male with an abnormal right 'curled' horn and a female with a horn at the Blackbuck National Park, Velavadar, Bhavnagar District, Gujarat State, India. We also provide a photographic record of a female with horns in captivity.
