There are 20 tentacles (directly counted), one polian vesicle and a single stone canal. The calcareous ring is well developed, but the connection between the single pieces is very loose (text- fig. 7i). The calcareous deposits of the body wall (textfig. 7) are ex- clusively triradiate tables with six large meshes and a high spire which is supplied with three long bifurcate teeth. In a number of tables the points of these ramifications bear a few other minute points. The deposits of the tube-feet (text fig. 7 5) are partly normal. ,. Mesothuria ita. 1. calcareous ring.

All these specimens are so characteristic that there can be no doubt as to their determination. The shape of the tables, which is quite constant, the very large lateral tube-feet and the constantly brown color, make it easy to recognise this species. Mesothuria ma was originally described from off Mo- rocco, and Deichmaxx showed that it is fairly commen in Wesi Indian waters. The present "Ingolf" records further show that it is not confined to the warm area of the Atlantic for which reason it may be supposed to have a wide dist
