The first part of the lateral radial canals are somewhat irregular, with a tendency to branch, and run parallel with the circular canal before rising up towards the apex. Som. Chelophyes contorta (Lens & van Riemsdijk), 1908. This species appears to be much more abundant in the West Tropical Indian Ocean than its ally Ch. appendiculata, though they occur side by side at most of the stations. During a recent examination of seven of the bottles of plankton brought back by 'Manihine' from the Gulf of Aqaba I have identified young specimens of Ch. contorta and eudoxids of the Endoxia rnsselli type. Since Chelophyes appendiculata was not found in the Gulf of Aqaba it is probable that these eudoxids are of the species contorta, but I have not yet been able to distinguish them from those of Ch. appendiculata. They are both of the type described by me (1932) as Eudoxia russelli. This species is not often taken, but it was one of the common species taken by the Great Barrier Reef Expedition; and Russell & Colman (1935) showed that it could not apparently withstand the conditions of the environment in the Barrier Reef lagoon during the period of lower salinity. We find it in the Indian Ocean in some catches associated with Enneagonum hyalinum, one of the three Barrier Reef species that was definitely able to withstand lowered salinity, and so was possibly well suited for life in coastal waters.
