In Sphagnuvi; reported by Prof. Gr. S. West from Giggleswick, West Yorkshire; and also from the North of Ireland. Loch Ness, Scotland (/. Murray). This is a rare species. It differs from H. papilio in the marginal compression of the test (the margin being obtuse), in its broader crown, and in the absence of lateral pores. 3. Hyalosphenia inconspicua G. S. West.
