As bearing upon the observations recorded by Mr. H. N. Milligan in NATURE of February 3, I should like to say that two of ten specimens of Eupargurus prideauxii, which have been kept in the aquarium of this institution since last autumn, died on January 23. The molluscan shell occupied by one of these specimens was that of Trochus magus, that occupied by the other was of Scaphander lignarius. Both shells were, as usual, enveloped by a specimen of the anemone Adamsia palliata. When I first noticed the dead hermit-crabs both lay on the gravel at the bottom of the tank with their ventral surfaces uppermost, and in both cases the abdomen was partially withdrawn from the molluscan shell. Both had been attacked and partially enveloped, one by two half-grown specimens of the asteroid Porania pulvillus, and the other by one rather larger specimen.
