Remarks

Most of the specimens collected during BANGAL 0711 were assigned to Policordia gemma as represented on Fig. 39E‒F . Nevertheless, a second species, represented by only three specimens and one shell, was present in sample V10 (1720 m) together with P. gemma and was tentatively identified in the preliminary INDEMARES BANGAL 0711 report ( Gofas et al. 2014b) and in Gofas et al. (2017) as Policordia atlantica Allen & J.F. Turner, 1974 .
