Material examined. Stn. COM 11 —20.xii. 2004, 22 m, S18: one sterile colony, 9 cm high, 2 slides ( MHNG INVE 53171 ). Stn. CAD — 12.iii. 2006, 25 m, S114: several sterile fragments, 1.2–3.4 cm high ( MHNG INVE 53368 ). Stn. ICA — 13.iii. 2006, 18 m, S120: one colony, 5 cm high, and smaller fragments, all sterile ( MHNG INVE 53377 ) .

Type locality. Passage de la Déroute, near Pirou, Channel coast of the Cotentin Peninsula, France .

Remarks. Although all the present material is relatively scarce and sterile, the presence of a few (between 1-3) secondary tubes (but no branches) creeping on the main stem, suggests that it belongs to Sertularella gayi .

World distribution. Widely distributed in the Atlantic and the northern Pacific ( Vervoort & Watson 2003). Recorded from the Magellan region, although apparently absent from Antarctic waters (Peña Cantero & García Carrascosa 1999).

Records from Chile. Previously unrecorded, but present at least along the coasts of southern Chile, between 42°23' S and 49°11' S. This is the first record for Chile .
