REMARKS
The species B. pumicea was originally described from a single female from Sumatra by Sluiter (1891). This species is fairly well known as it has been recorded and redescribed from the North Atlantic by DattaGupta (1981) and Biseswar (1992). Bonellia pumicea is closely related to B. plumosa DattaGupta, 1981 but differs in the structure of the body wall and blood vascular system. Stephen & Edmonds (1972) have mentioned the presence of white papillae as the main feature to separate B. pumicea from the rest of the species in the genus Bonellia. According to DattaGupta (1981), B. plumosa has a broad ring sinus located at the junction of the pro- and mid-intestine.
The discovery of this species from the West African continental margin is a new record and extends its range of distribution southwards in the Atlantic.
