However, the poor condition of these fragments makes it difficult to ascertain whether these are pouches, or whether they are simply ‘swellings’ of the body wall where the epidermis has split. The larger of the two fragments also contains several different sizes of eggs. Due to the condition of the specimens, nothing more can be interpreted from them. No eggs observed in anterior fragments.

The colouration originally described by Gravier was pale pink in the anterior, with a brownish posterior. He noted brown pigmentation on the palps, which increased towards the distal tip, and dark tinted band outside and in immediate contact with the external row of papillae. This pigmentation has been lost in the preserved material, which is now generally pale, with light brown/yellow colouration. Staining with methyl green shows no clear pattern, but an overall diffuse stain. However, after staining, when much of the stain has dissipated, green speckled areas associated with the ventral swellings can be observed as well as, a parallel longitudinal stripe either side of the mid–dorsal line in thorax (at the level of the superior processes), strong particularly between chaetigers 1–4. Some staining evident abdominally between the parapodia.

Several features observed differ from those of the original description of this species, in particular, the bilobed nature of the lamellae of the thorax.

material. The bilobed lamellae are particularly delicate, and are prone to splitting along the junction between the two lamellar regions. As a consequence, many of the specimens have lost the distal portion of these lamellae, making a complete set of drawings from one specimen difficult. It is entirely possible that his figure was drawn from a parapodium in which the lamella was incomplete, or drawn from a parapodium in the anterior thorax. Gravier also stated that dorsal cirri, above the lamellae, were not present on the 1st or the 9th chaetigers. Small superior prechaetal processes (DML) have been observed to be present on these chaetigers within the
