Both specimens well relaxed, virtually identical to each other with black linear pattern composed of four lines: median pair merges between rhinophores and extends to margin anteriorly, posteriorly they remain separate to anus or meet outer lines at level of anus. Outer lines straight medially but scalloped laterally in extensions to margin; scallops not symmetrical on each side, with five on left and six on right on both specimens.

sketches identical to illustration in Brunckhorst, 1993; although only one collector comments on blue colour, both comment on ochre-yellow rhinophores, visible in photographs of both specimens. Anal papilla ochre, very near posterior margin. Photograph of 19 mm specimen (Plate 77) shows central area between black lines to have been blue, outer scalloped areas were granular white with blue spots along margin. Faint orange tinge behind rhinophores (and generally) is a photographic artefact.

The tubular pharynx is narrow and turns on itself to pass through the nerve ring before joining the muscular oesophagus, which is banded and brown-black. There is a long narrow cream oesophagus which enters the digestive gland at approximately the one third mark (fig. 28C). The anal papilla is slightly swollen.</paragraph>
