papillae arranged along the margin. The rhinophore sheaths have a narrow stalk and the posterior papilla is slender, about three times taller than the three anterior and anterolateral papillae. The rhinophore sheaths and anterior papillae are colored as in the rest of the body, while the tall posterior papilla, on each sheath, is mostly white. None of the papillae have an orange subapical ring. The rhinophores are translucent white with a minute orange tip and have approximately

lamellae. There are five to six pairs of dorsolateral processes, with one or two small, unpaired processes near the tail. The first dorsolateral process on each side has two or three bulbous papillae, usually one on the outside and two on the inside. The processes in the second and often the third pair have a single papilla on the outer side. The fourth through sixth processes are usually unbranched, lacking any papillae. They are arranged irregularly on either side of the dorsal midline. The final one or two single processes are very small and located in the dorsal midline. Like those on the rhinophore sheaths, the bulbous papillae are mostly white, without orange subapical rings. Small tripinnate gills are located on the inner surfaces of the first four to six pairs of processes, and become smaller posteriorly. The reproductive opening is on the right side, about two thirds of the way from the rhinophore stalk to the first dorsolateral process. The anus is more dorsal, also on the right, between the first and second dorsolateral process, a bit closer to the second.

). A long unpaired oral gland is found ventrally. It extends back from the ventral side of the mouth to the region of the reproductive system. A pair of small, yellowish salivary glands is attached to the posterior side of the oesophagus. The oesophagus is relatively long and runs back to the rounded stomach. The two anterior digestive glands open on the upper surface of the stomach, and each has a single branch entering the first dorsolateral process on its side. The posterior portion of the digestive gland opens on the lower left surface of the stomach. All but the first pair of dorsolateral processes receive branches from the posterior portion of the digestive gland. The posterior chamber of the stomach is thin-walled and its anterior section is armed with longitudinal rows of stubby brown chitinous spines. Because of the distortion in the preserved specimens it was impossible to accurately count the number of rows of spines (

The hermaphrodite duct runs beneath the stomach on the left side, between the stomach and the posterior branch of the digestive gland before expanding into the ampulla which lies on the dorsal side of the female gland mass. On leaving the ampulla, the hermaphrodite duct shortly branches to give rise to the vas deferens and the oviduct, which descends into the female gland mass. The long and greatly folded vas deferens appear to be enclosed in a thin layer of prostate gland tissue, except for a short narrower length near the penial bulb. The opening into the penial bulb is armed with two irregular rings of chitinous hooked spines (
