Type material: BMNH 1884.4.22.27 (holotype). Station 145, off Prince Edward Islands (46° 40’ S – 37° 50’ E), 275 to 567 m depth, 27 December 1873. Type locality: off Prince Edward Islands, Indian Ocean. Analysed material: BMNH 1884.4.22.27 (holotype; specimen and one slide containing sections of the skeleton). BMNH 1955.12.13.10 (one slide containing sections of the skeleton) and BMNH 1955.12.13.11 (one slide containing sections of the skeleton), both from Plymouth; R.W.H. Row collection. Morphology: The colour of the holotype in ethanol is white (Fig. 4A). It is a fragment with tubular shape and apical osculum, measuring 4 cm x 0.2 cm (length x width). The surface is slightly hispid. Syconoid aquiferous system (Fig. 5). Anatomy: The skeleton is typical of the genus Amphoriscus, and the inarticulation is evident (Figs. 4D and 5D, E). The cortical region is formed by giant tetractines and small sagittal triactines (Figs. 4B, C). The apical actine of these giant tetractines may reach the atrial cavity. All the analysed samples exhibited trichoxeas perforating the cortex without forming tufts (Fig. 5C). The subatrial region is formed by abundant triactines with long unpaired actine and rare tetractines (Fig. 5D). The latter are more frequent in the specimens BMNH 1955.12.13.10 and BMNH 1955.12.13.11 but also occur in the holotype. Additionally, in these specimens from Plymouth, we also observed a few modified subatrial triactines in which the actines that surround the atrial wall have different lengths and shapes (Fig. 5E). These spicules were found in the sections. Due to the occurrence of other spicules overlapping them, it was not clear if they were pseudosagittal. All the subatrial spicules point their unpaired actines to the cortex, in opposition to the ...
