Serpula watsoni Willey, 1905

Serpula watsoni Willey, 1905: 317; Imajima 1977: 91 –92; Mak 1982: 609; Morton and Morton 1983: 278; Wang and Huang 1993: 7; Pillai 2009: 140 –143.

Remarks. Not a new record. As stated by Mak (1982: 609) the species can easily be recognized by its long opercular funnel which has a deep hollow. A further distinguishing character is its radial grooves, extending for almost the entire opercular funnel length (Imajima 1977 fig. 2a).
