ON A COLLECTION OF FEATHER STARS. OR COMATU-LIDS, FROM JAPAN. By Austin Hobart Ci.akk, Of tlir United Stales Bureau of Fisheries. The United States National Museum has recently received from Mr. Alan Owston, of Yokohama, a small, but very interesting, collec-tion of unstalked crinoids made by Mr. Owston in Tokyo and Sa-gami bays and in Suruga Gulf, deposited by Mr. Frank Springer for study in connection with the material obtained in somewhat deeper water by the U. S. Fisheries steamer Albatross. Although containing only one hundred and thirty-one specimens, including forty-eight of Calometra multicolor and thirt}' of Cyllo-metra alb o purpurea., there are three species new to science, Coniaster i7nbricata, Eudiocrrm/s rariegatus., and Thalassometra komachi., one which was previously known only from a single Challenger specimen, ' Charitometra distincta, two previously known only from the types in the Museum of Comparative Zoology, C omjjsometra serrata and Iridometra psyche., and three, Himerometra subccannata, Thalasso-metra aster., and Charitometra lata., known only from the types in the U. S. National Museum. Of especial interest also is a series of seven specimens of Tropiometra afra, affording an opportunity for a direct comparison of Australian and Japanese examples of this remarkable species.
