(®gure 13B). The shape is irregular, but usually the body narrows posteriorly to a distinct peduncle, which terminates in one or more thin test processes. The test is thin and translucent, the surface is smooth or has a small amount of sand and mud adherent to it. In most specimens apertures are sessile, well removed from each other and situated on the opposite ends of the upper surface, but in some strongly contracted specimens there are pronounced diverging siphons. The siphons, however, appear only on the body itself, and not on the test, which is no longer attached to the body in many specimens. Probably both apertures have six lobes, but these were di cult to count.

The muscles around the apertures are diOEerently developed: the atrial siphon has strongly developed circular muscles, and few thin and short radial muscles, while circular muscles of the branchial siphon are weak and do not extend below the branchial velum. A number of thick muscles radiate from the branchial aperture, some are short, but others continue to the end of the body. Short parallel transverse muscles form a band on each side of the endostyle. The longitudinal muscles are con®ned mostly to the posterior end of the body and between the circular muscles of the atrial siphon and the band of ventral transverse muscles (®gure 14).</paragraph>

A high velum well separated from the tentacles makes a distinct dorsal V. An unusually thick prepharyngeal band runs close to the velum, or even on the velum laterally and ventrally, and makes a pronounced V dorsally, with the tip curving to the left side. The dorsal tubercle was not detected, the neural ganglion is on the left of the dorsal V. Each side of the branchial sac has three double rows of about six wide stigmata with no more than 1.5 coils. The stigmata are enlarged and the tissue between them is greatly reduced. Radial parastigmatic vessels are present on some stigmata. The double rows are separated by two transverse vessels, each with a high triangular dorsal languet. One or two low ¯attened papillae are present on each transverse vessel on the left side, and two papillae on the right. The ventral margin of the branchial sac is attached to the body wall far from the endostyle, along the line between the lateral longitudinal and ventral transverse muscles.</paragraph>

The anus in all specimens examined is small and apparently has a smooth margin. The gonad, consisting of a central ovary surrounded by large oval male follicles, is present in the gut loop. The male and female ducts are thick and contain large eggs and spermatozoa. The gonoducts follow the rectum and open near the anus.

, their specimens cannot belong to any known species because of the`peculiar muscle arrangement’. They have strong circular muscles around the apertures and`two lateral symmetrical areas, which come together on the dorsal axis’. It is di cult to understand without a ®gure what these`symmetrical lateral areas’ are, but they may correspond to the longitudinal muscles on the body sides in the present species. In any case it seems unlikely that at such a great depth and in the same place two diOEerent species of the same genus may exist. The Monniots’ specimens were not in a good condition and this may explain the mentioned diOEerences.
