James Shoal, along with its two nearby features, Parsons’ Shoal (Betting Tugau, 八仙暗沙, 9.35 km due south) and Lydie Shoal (Betting Mukah, 立地暗沙, 27.94 km west-southwest), were recognised by British surveyors in the early 19th Century via many of its surveys. James Shoal first appeared on the British Admiralty Chart in the 1870s. In 1933 a government committee of the Republic of China gave Chinese names to many features in the South China Sea. These were mainly translations or transliterations of the names on the British charts.[11] The name 'James' was transliterated as Zeng Mu (the letters 'J' and 'M'). 'Shoal' was translated as 'Tan' - meaning sandbank. It appears the Chinese committee wrongly thought that James Shoal was an island. In 1947 the RoC changed the name to 'Ansha' (暗沙)[12] - meaning 'shoal' or 'reef'.
