Remarks.— Hokkaidoconcha hikidai has been recently described by Kaim et al. (2008a). Since preparation of the latter paper we have found additional specimens of this species. Regrettably none of these has the protoconch preserved. Nevertheless we found some specimens in the seep periphery (see zonation of the Yasukawa seep in Jenkins et al. 2007b) with original shell microstructure preserved. The shell consists of a thin prismatic outer layer, a thick cross−lamellar middle layer, and a moderately thick prismatic inner layer ( Fig. 11B View Fig 3 View Fig ), a shell layer organization known from Provannidae ( Kiel 2004) .
