Trianguloscalpellum album : Zevina, 1981a: 308–309 . Material examined. Holotype NHM UK 2013.1114 and paratype NHM UK 2013.1115, Stn 214: Pacific , Western Central (off Meangis Island , Malay Archipelago ); 914 m . Supplementary description. Chan et al. (2009) , as T. weltnerianum . Distribution. Pacific, Western Central: Malay Archipelago, Japanese and Taiwanese waters. Known depth range 656 to 914 m . Habitat. On Crinoidea. Remarks. Pilsbry (1911) pointed out that T. album is morphologically similar to T. weltnerianum and noted that the difference between the two species is mainly that the plates of T. album are smooth. However, Hoek (1883) commented on the "beautiful striation" of the T. album plates under the microscope. Our observations of the holotype confirmed Hoek’s (1883) comment, therefore T. weltnerianum is here considered to be a junior subjective synonym of T. album .
