which extend about threequarters of the distance from the apical sense organ towards the mouth. Among them, there are four subsagital comb rows on the lateral part of the body and four subtentacular comb rows on the middle part of the body. In addition to the meridional canals, there are two lateral paragastric canals, which arise from the funnel and extend down the middle of the broad sides of the animal. There is no axial funnel-tube, but instead there are two lateral tubes which extend upward from the funnel to the two halves of the pole plate. Each of these tubes opens by an excretory pore on alternate opposite sides of the figure “8” shaped pole-plate. The sense organ at the aboral pole is not fringed with a row of long-branched papillae (Fig. 5C). The aboral end is rounded, while the oral end is almost straight and can be wider than the body width.
