DISTRIBUTION. To date known only from Japan and the Philippine Islands. 
Shell elongate-biconic, teleoconch with 7 whorls and protoconch with 2-24 
smooth white embryonic whorls, 2-3 post-embryonic whorls clathrate,later whorls 
with 2-4 flattish, low spiral cords at posterior of suture, body whorl with finely 
punctate spiral grooves, aperture with up to 15 lirae in mature specimens, columella

As has been remarked by Kilburn (1986) this species is rather atypical for the 
genus Anarithma not only in general shape but also in size (up to 25.0 mm) and lack 
of axial sculpture. A specimen from Mururoa Atoll, Tuamotus (/eg. C.Beslu) closely
