Material examined. AM W.28421 (4, as Pseudovermilia ), Granite Head, underside of boulders on rock, little sand subtidally, coll. H. ten Hove, 18 Jun 1983; AM W.45052, MI QLD 2406 (2); ZMA V.Pol. 5536 (separated from ZMA V.Pol. 4776, Pseudovermilia or Semivermilia ), stn.18, lagoon near east entrance, sheltered side of reef, near sandy bottom, 2–20 m, coll. H. ten Hove, 3 Mar 1986; ZMA V.Pol. 4798 (13, as Semivermilia ), North Reef, 14°40'S, 145°27'E, underside of boulders on rock, low tide, little sand, coll. H. ten Hove, 22 Jun 1983; ZMA V.Pol. 5537 (4), Mermaid Cove, underside of boulders in surf, subtidal & low intertidal, coll. H. ten Hove, 20 Jun 1983.

Diagnosis. Tube white, more or less trapezoidal in cross section, with one erect and two oblique longitudinal keels; keels irregularly serrated and ending in tooth over entrance; just above anterior basal attachment area there are two more projecting teeth. Tube at most with narrow lateral flanges. Operculum consisting of an ampulla bearing 3–8 chitinous tiers (narrow diabolos), the most distal may bear a short spine.

Remarks. As in 1986, one of us (HtH) compared the present material side by side with 2 paratypes of Semivermilia uchidai (ZMA V.Pol. 3563, Solomon Islands, Nggela group, Makambo, 18 Aug 1984, det. Imajima & ten Hove 1986). The sample ZMA V.Pol. 4776, registered under field identification Pseudovermilia spec ., contained three specimens of Pseudovermilia pacifica , 1 specimen of the tube brooding Semivermilia annehoggettae n. sp. and one specimen identical in size, shape of operculum and three keeled tube with S. uchidai . See also remarks after S. pomatostegoides .

Distribution. Mediterranean Sea, East and West (sub)tropical Atlantic, Seychelles, Red Sea,? South China Sea; Qld, Australia.
