); this aspect is not due to contraction, the internal layer is smooth. The longitudinal and transverse muscular fibres are dense in a continuous layer making the body wall opaque. About 40 simple oral tentacles in 3 orders of size form an anterior ring. The peri-pharyngeal band, in a single rod, draws a wide dorsal indentation. The dorsal tubercle opens in a U-shaped slit. The dorsal lamina is a tall smooth-edged membrane (
