Show 1900.] MR. F. P. BEDFORD ON MALAYAN ECHINODERMS. 293 size than any of the specimens examined by M. de Loriol. found small Lamellibranchs and an entire Hoplodactgla in the stomach. I do not remember to have seen any previous mention of Asteroids feeding upon Holothurians. Distribution. Previously known from Penang. The specimens appear to agree in all essential details with the original description : the general facies is, however, somewhat different, the arms, which are six in number in all individuals seen (about 30), being longer and narrower in the Malacca form. As M. de Loriol had received as many as fourteen specimens from Penang, this difference seems to be in some way correlated with the locality. The large pedicellariae on the adambulacrals mentioned by de Loriol as present in some cases appear to be constant in our specimens, and the anatomical details are subject to very little variation. Contrary to the general rule in long-armed starfish, the arms had not undergone regeneration in any of the specimens. It is a striking fact that this species was not met with at Singapore, where an apparently similar habitat is available. E. r.
