The chief specific name used here is Ceratosoma trilobatum (J. E. Gray, 1827) (s. l.) which is said to comprise C. cornigerum (Adams & Reeve in Adams, 1850) (s. s.) as a junior synonym. In Japan there occur three sorts of color variation among the individual specimens of C. trilobatum (in the meaning of C. cornigerum s. s.). C. bicolor Baba, 1949 is left for further study.
