This fine handsome specics is fairly common at Lord Howe Island. It is generally found at or about low tide line, inhabiting the shells of Turbo imperialis, Gmelin. Numerous examples were obtained during the visit of Mr. R. Etheridge, Junr., Mr. J. A. Thorpe, and the writer, in 1887. These specimens appeared in the report on "Lord Howe Island: Its Zoology and Physical Characters," under the name of Galcinus elegans, Milne-Edwards, the error arising from a comparison with a wrongly named example in the collection. Since 1887 many specimens have been received from the same region, and about three years ago I obtained a living specimen at Maroubra Bay, near Sydney. During the visit of the "Thetis" to Lord Howe Island in March, 1898, Messrs. Etheridge and Waite secured six examples, two of which are selected for illustration and description.
