Aster opsls pulvillus, O. F. Mullek, were not met with beyond the 100-fathom line. A curious little group of cushion stars, hitherto supposed to be con- fined to high latitudes, were represented by l?te raster militaris, M. and T., and P. pulvillus, Sars, and by two forms new to science,—one, Korethraster his- piclus, sp. n., with the whole of the upper surface covered with long* free paxilhe like sable brushes (Fig. 15). Ranges of delicate spatulate spines border the. Pin. 16. -Hyvienastcrpelluddus, Wyville Thomson. Ventral aspect. Natural size. iNo. 59) ambulacral grooves. As in Pteraster, there is a double row of conical water feet. The other genus (Fig. 10) is perhaps even more remarkable. The star-fish is very flat, the dorsal surface covered with short paxilhe which support a membrane as in Pteraster. A row of spines fringing the ambulacral grooves is greatly lengthened and webbed, and the web running along the side of one arm meets and unites with the web.
