To the recently published paper by my father, “Palæontology of the Coasts of the Arctic Lands visited by the late British Expedition,” etc., I contributed some notes on the Polyzoa obtained during the progress of the Expedition from the Palæozoic rocks of the regions visited. Amongst other forms I referred at some length to Dr. F. Toula's genus Ramipora, and pointed out its affinities to various genera of Palæ Polyzoa, and more particularly to Synocladia, King, in the following words:—“ It appears to differ from the first of these” (i.e. from Synocladia) “in the absence of dichotomization of the stem and primary branches, so far as the remains of it are known to us; secondly, in the bilateral symmetry of the latter; thirdly, in the fact that the cells all open on the same plane on each side the median keel, whereas in Synocladia the stems and branches are divided longitudinally by several carinæ, between which the cell apertures occur. Again in Ramipora both aspects of the polyzoarium are carinate, but in Synocladia only one. Lastly, in Synocladia the dissepiments all appear to be regularly celluliferous, but in Ramipora this does not appear to hold good to the same extent.”

Certain zones of the massive grey dolomite belonging to the Niagara Formation in North America are so largely composed of fossil corals as to indicate similar conditions of formation to that of the coral reefs of the present age. Perhaps no better examples of these Palæozoic coral reefs could be found than those which are exposed in many tracts of the surface of the Great Manitoulin Island, which are literally covered with complete and fragmentary corals in a silicified condition, which have been weathered out of the matrix of hard dolomite in which they had been imbedded. The great majority of these corals belong to the well-known genera Favosites, Halysites, Heliolites, Alveolites, Cænites, Syringopora, Strombodes, Cyathophyllum, Zaphrentisand Omphyma, and many of the species are also common to the Silurian rocks of Europe. A recent search in the dèbris of one of these ancient reefs has brought to light a coral which appears to belong to a new genus, with the following characters.

The great geological interest which attaches to the fossil remains of the Musk-ox or Sheep (Ovibos moschatus, Blainv.), found in British Pleistocene deposits, and the few instances hitherto recorded of their occurrence (together with a recent discovery brought to my notice), have suggested to me the desirability of a brief enumeration of them.

Recent studies of the glacial phenomena as exhibited in the State of New Hampshire and adjoining regions enable us to maintain the following propositions.

The evidence under this head is necessarily a compilation; the very exceptional exposure of the old forest ground, and the nature of stream tin sections, leaving no room for personal investigation. The names of the observers are in most cases sufficient vouchers for the accuracy of their statements. The submerged forestare given first stream tin gravels to the general growth of the forests. The forest bed overlying the stream tin which Mr. Carne rightly synchronizes with the forest beds on the coast may represent a very brief portion of a long period of forestial growth.
