Ground colour semi-translucent pink with black line surrounding central region; four smaller perpendicular lines extending to margin in opposing pairs. Central region bears high median crest and lower lateral one either side. Crests composed of irregular granular compound tubercles, opaque in comparison with body. Rhinophores and anal papilla located within black oval. Rhinophores translucent pink, 12 to 19 oblique lamellae; anus conical, located on last tubercle of central crest, visible on larger specimen Plate 76; both extend through raised rims. Outside the black ellipse, a row of large tubercles is followed by a row of smaller ones, also compound and opaque pink-white in life. Metapodium projected beyond the mantle in life. Black band in crevice where hyponotum meets foot behind gills; this black line extends posteriorly along top of metapodium in one specimen. Gills black, genital opening a white swelling on right side. Propodium nearly divided in smaller specimens and notched in the largest. White head and fused oral tentacles, very short with groove on outer sides (figs. 27A).</paragraph>

Internally, three specimens from the Maldives proved to be identical (the fourth was badly preserved). One specimen (95 mm) everted its mouthparts completely during preservation (Fig. 27B, D). The mouth leads to a short oral tube which, in one specimen, is narrow and contracted like a concertina (Fig. 27C). Where it thickens into the pharyngeal bulb, there is a band of pigment, incomplete dorsally. The pharyngeal bulb is extensible, as evidenced by the specimen illustrated in Fig. 27D. A sharp demarcation exists where the pharynx joins the bulb; the bulb turns anteriorly and loops posteriorly, passing through the nerve ring. The posteriorly-directed portion is of equal length to the anteriorly-directed segment, and inserts into the oesophagus at a constriction. The oesophagus is a thicker banded tube leading into a sac-like structure with which it is continuous (the muscular oesophageal segment), and opens into the digestive gland. The pathway from the oesophagus to the digestive gland follows a Z-shaped route, located in the anterior quarter of the digestive gland. Almost in a continuous line with

|
||
oesophagus, a long muscle attaches and runs under the intestine and pericardium to emerge on the other side. The intestine then runs along the midline to the anus.
