Explanation of Plates.
Plate 1.
These figures are not drawn to the same scale; sizes are given in the key. Fig. 1. Anterior end of Stichopus mollis showing ventral side bearing tube feet, and the tentacles with disc shaped tips (T) surrounding the slit like mouth. Fig. 2. Psolus neozelanicus, dorsal side showing imbricating scales. Fig. 3. Psclidiella nigra, latero-ventral view showing distinct light coloured sole bearing tube feet round the edge and a double row along the centre. Fig. 4. Cucumaria ocnoides, side view showing tube feet restricted to three rows (two showing) in the middle third of the body. Fig. 5. Paracaudina coriacea. Fig. 6. Profuse branching found in the tentacles of Order Dendrochirota. In preserved material the branching may appear to be much more crowded than illustrated. Fig. 7. Finger like processes of tentacle typical of many of the Order Apoda. Fig. 8. Trochodota dendyi.
