Aglaophamus posterobranchus	29mm for 53 ch (incomplete)	ovate, longer than wide	involute	9	until end of fragment (=ch. 53)	unadorned (but erect, enlarged lobe above notopodia present	very small, conical
Aglaophamus cf. foliosus	26-41mm for 65 and 75 chaetigers (complete)	rounded, about as long as wide	involute	3 (tiny!)	absent from app. last 5 ch.	with very enlarged postchaetal lobes in neuropodia	very large, foliose with produced tip
