In the GeologicalMagazine for July, 1874, I gave a description and figures of this species, and also that of a shell I referred with some hesitation to Aviculopecten ellipticus, Phillips, closely resembling the forms referred to P. Sowerbii, but differing in the form of the ears, which are after the normal type of the Pectinidœ, and not connate, with a re-entering angle between them, as in P. Sowerbii.

When we speak of Newfoundland, we speak of England's oldest and yet almost unknown Colony. When we look at its rocks, we shall find that they also are old, and from the metamorphisms and contortions they have suffered are almost unrecognizable. The first geologist who journeyed round the rugged shores which gird the island, and across the marshes and thickets which cover its interior, was the indefatigable Jukes.

For some years past, the serious attention of several eminent malacologists has been directed to the endeavour to determine the affinities of the Brachiopoda, or the exact position the group should occupy in the animal kingdom. The Invertebrata have been grouped into five sub-kingdoms, namely, the Frotozoa, Cœlenterata, Annuloida, Annulosa, and Mollusca, and for many years the Brachiopoda have been considered to constitute a separate class in the subkingdom Mollusca, a view still maintained by some distinguished naturalists.

In the Quarterly Journal of the Geological Society (vol. xxxiii. p. 142) is an important paper by Mr. Helland, on Fjords, Lakes, and Cirques in Norway and Greenland. In this he notices a theory of mine on the formation of cirques which was published in the same journal (vol. xxvii. p. 312). As I mentioned in a note attached to his paper, he somewhat misunderstands me, supposing apparently that I describe only cirques of a small size,—the fact being, that, so far as I know, the Alpine cirques are quite commensurate with those of Norway. This, however, is of slight importance. My present purpose is to give reasons why, after further observations in the Alps and Pyrenees, and even in the British Isles, I still prefer the explanation then advanced, that the cirques are mainly produced by the combined erosive action of streamlets, to the one given by Mr. Helland, that a cirque is a result of glacial action.

The following is an abstract of another of the papers forwarded to me from Graz, to which I alluded in the April Number of the GeologicalMagazine. The author first states that the opinion he had formed, that all the Floras of the present time were represented in the Tertiary Flora of Europe, has been still more confirmed by later researches, and then enters upon his more immediate subject.
