Excerpt from Transactions of the Linnean Society of London, Vol. 11 I desire at the outset to acknowledge my indebtedness to Dr. W. T. Calman, of the British Museum, for his kindness in seeing this paper through the press. The following Short descriptions are those published in my paper, but with some slight amendments, due to the Opportunity afforded me by Mr. Geoffrey Smith, Fellow of New College, Oxford, of seeing drawings of a new form, evidently also belonging to the order Anaspidacea, which he discovered on a recent visit to Tasmania.
