Thick crowded circular muscles are present only on siphons while on the whole rest part of the body wall only occasional thin transverse muscle fibers can be detected after staining. In contrast the longitudinal muscles are well developed and continue to the end of the body, although muscle fibers are much thicker on its anterior half.

Prepharyngeal band runs close to the velum and draws a circular line with shallow dorsal V around large oval dorsal tubercle which has C-shaped opening. Dorsal lamina is a high plain-edged membrane. The branchial sac has one shallow but distinct fold on each side running on some distance from the dorsal lamina, otherwise its wall is quite smooth. Internal longitudinal vessels are very numerous and closely set, with no more than one stigmata between two adjacent vessels.</paragraph>
