Cloeosiphon aspergillum, Quatrefages.

Cloeosiphon aspergillum (Quatrefages), Selenka, Semper's Reisen. Arch. der Philippinen iv., Die Sipunculiden, p. 126, pl. ii. figs. 23, 24; pl. xiv. figs. 214-216.

A solitary example is somewhat doubtfully referred to this species. The specimen is 6 cm. in length, the proboscis is damaged and no hooks were available for examination. In other respects it agrees fairly well with the published description.
