Ceratocephale sp. 1

Diagnosis.

Eyes absent; tentacular cirri all very short, longest extending just beyond peristomium; cirrophore of dorsal cirri not significantly expanded; double ventral cirri from chaetiger 3, posterior one twice length of anterior one. Specimens too small to dissect to observe paragnath/papillae arrangement.

Remarks.

Specimens do not fit descriptions of any named species. Members of the genus are typically common in deep-sea samples, however, in this study they were rare.

Records.

3 specimens. Suppl. material 1: ops. 79, 89, 110 (AM).
