(Fig. 29; Table 27)

Figularia figularis var. japonica Silén, 1941: 115, figs 174–177.

Figularia japonica: Yang et al., 2018: 225, figs 28, 29.

Material examined. Holotype by original designation SMNH-Type-9377 (not figured), North Pacific, Yokohama Bay, Tokyo, Japan; depth 115 m. Leg. Vega Expedition 1878–1880, Station 1083 . Paratypes UPSZTY 2467 (three colonies on calcareous bioclast fragments, Fig. 29), UPSZTY 191155 (one colony encrusting a pectinid shell, not figured)], Goto Islands, Kyushu (33°41' N; 128°50' E), Japan; depth 110 m; from a sandy sea-bottom. Leg. Prof. S. Bock 1914 .

Remarks. A recent, updated description of this species is given in Yang et al. (2018), and therefore omitted here. Yang et al. (2018) also elevated the rank of the taxon from subspecies to species.

The holotype designated by Silén (1941) was collected at 115 m depth at Tokyo Bay from a muddy sea-bottom, and is kept in ethanol at the SMNH. Given the apparent fragility of the specimen, SEM study was avoided. As for Tricellaria dubia, the specimens illustrated here are listed in the original publication as part of the type series and they can be considered paratypes based on the article 72.4.5 of the International Code of Zoological Nomenclature (ICZN, 1999) . Holotype and paratypes were collected in two separate expeditions.
