Their origin as longitudinal muscles is, however, shown by their position in young developing zooids (Text-fig. 16C, ). A few narrow and irregular transverse strands are present on the thorax. Only the young developing stages of the zooid have transverse muscles in the abdomen () and they are confined to the upper part of it. Branchial sac. The large oral tentacles number twenty-six to twenty-eight and are arranged in a single circle. The dorsal tubercle (Text-fig. 16D) is small, with a simple transverse oval slit. B mm cm.
