 In 1880 , the diamond stingray was described twice by three American <unk> : as <unk> <unk> by David Starr Jordan and Charles Henry Gilbert in Proceedings of the United States National Museum , and as <unk> brevis by Samuel Garman in Bulletin of the Museum of Comparative <unk> . Jordan and Gilbert 's account was published in May while Garman 's was published in October , making <unk> ( feminine dipterura ) the correct name as it was published first . However , when Garman synonymized the two in 1913 he <unk> gave precedence to brevis , leading to long @-@ standing confusion . Both <unk> and <unk> were later synonymized with the genus Dasyatis , but many authors still listed D. brevis in place of or in addition to D. dipterura . Garman also synonymized the Hawaiian stingray ( D. <unk> ) with D. dipterura in 1913 , which has since been followed by most authors but requires more study for confirmation .
