A. Adams, 1854
This species was originally described from "Eastern Seas" and later by Watson (1886) from the Philippines. Subsequently it has been reported by various authors from Japan, and recently from Hong Kong.

It is difficult to be sure from the short unillustrated original description just what Philine orientalis is. This animal from Hong Kong is possibly Philine orientalis A.Adams but until more information is available on the anatomy and shell variation of species of Philine from the north-western Pacific region, a firm identification is impossible.
