Unpaired lateral pouches found posteriorly on two specimens, on chaetigers 24L (NMW.Z.2010.037.0007) and chaetigers 26L, 28R and 30L (MNCN.16.01/13231). Pouches posteriorly open, however, very large and convoluted, more akin to anteriorly open pouches (especially those on chaetiger 26L). Posterior unknown.
