Potamethus sp.

Remarks.

Identification is to genus only, based on presence of dorsal lamellae joining dorsal collar, and presence of extremely long-handled thoracic uncini and companion chaetae, paleate inferior thoracic chaetae, and broadly-hooded superior thoracic chaetae. Possibly is the same as above specimens of Potamethus cf. scotiae , but specimens were small, incomplete and/or degraded too much from poor preservation whilst in their tubes.

Records.

2 specimens. Suppl. material 1: op. 53, 121 (AM).
