Policordia sp.

Material examined

GALICIA BANK • 3 spm, 1 sh; 42°41.87′ N, 11°26.71′ W; 1720 m; 8 Aug. 2011; BANGAL 0711 V10; MNCN .

Remarks

This second species differs in being less inflated and having an outline with a more produced posterior end, resulting in that the shell is longer than high (higher than long in P. gemma ). Whereas our specimens agree in shape and size with the specimens from the Porcupine Sea Bight (1630‒1640 m) illustrated on the NMW website ( Oliver et al. 2016), we are reluctant to confirm this identification taking into account the taxonomic uncertainty surrounding P. atlantica .
