Explanation of Plates V.-VII. Plate V. Fig. 1. Carpophyllum angustifolium, J. Ag. Bay of Islands; collected in January; R. M. L. Fig. 2. Carpophyllum phyllanthus, Turn., Hist., iv. Both specimens are from the same plant, which was gathered at Lyall's Bay in the month of September. Plate VI. Fig. 1. Carpophyllum maschalocarpum, Turn., Hist., iv.

Art. XV.—On New Lichens from Australia and New Zealand. By James Stirton, M.D., F.L.S., &c. (Continuation of Paper in Trans. N.Z. Inst., vol. xxx., p. 382.) Communicated by T. W. Naylor Beckett, F.L.S. [Read before the Philosophical Institute of Canterbury, 6th September, 1899.] Sticta rubella, Hook., presents obstacles to a complete determination, inasmuch as the original specimens are barren.

I am extremely sorry I can only discriminate two or three of the specimens in this parcel. The rest seem to have been soaked, almost macerated, in
