. The shallow waters recorded in the western Pacific afford a route for gene flow between the Indonesian and western Pacific populations of this species and those in the Indian Ocean, the Cape Basin and the Atlantic Ocean.

long, with the six large, characteristic and conspicuous pinnate arms surrounding the branchial aperture and the body coming to a point posteriorly in the small and inconspicuous atrial opening inclined postero-dorsally. Generally long hairs that enmesh sand are on ventrum and left side of the body but are absent from the other side where a thin layer of sand adheres to the test. The characteristic buccal cavity is produced forwards at the anterior end of the body, its margin lined by the six pinnate arms, the dorsal arms being longer. Strong circular muscles are in the body wall of the buccal cavity and a band of circular muscles is in the body wall behind it. Inside these circular muscles are longitudinal bands that extend posteriorly onto the anterior half of the body. Some short transverse muscles also extend across the dorsal surface along the remainder of the body. The inner walls of the pharynx have some concavities and pouches from which patches of ciliated stigmata open to the two anterior horns of the atrial cavity. The thick vertical oesophagus opens into a large curved stomach about three-quarters of the way down the body and a rectum curves around the stomach from its distal end and opens at the base of the small atrial siphon at the posterior end of the body. Bunches of branching testis follicles are at the proximal end of the long tubular ovary on each side and a large kidney with a conspicuous concretion is present. Gonads are partially embedded in a fleshy thickening of the body wall on each side. A long ligament separating the atrial cavity into right and left chambers attaches the mid-ventral line of the gut to the body wall.

The specimens conform to those previously recorded. Difficulties and ambiguities in interpreting their morphology often arise through confusion in the terminologies used to describe them and from misinterpretation of the homologies of many of their organs. Most aspects of the morphology of species in this family appear to be closely related to structures in the family

. They are distinguished from the latter family principally by compelling reductions in their filter feeding capacity.

This orientation suggests the possibility that the food organisms of these specimens are interstitial rather than planktonic or pelagic.</paragraph>
