We are glad to intróduce to our readers a portrait and some account of the life-work of the distinguished Palæontologist to the Geological Survey of Canada, who has now held the office for thirty years.

For many years it has been known that Ichthyosaurus was a viviparous reptile, but until quite recently the British Museum has not possessed a specimen with contained embryos. This deficiency has now been supplied by the acquisition of two fine skeletons, which are worthy of special notice.

(xxviii) The road from Llanarmon to Graianryd practically traverses the whole limestone sequence. The following fossils were obtained from the quarry about half a mile north of Llanarmon, by the roadside, where some 20–30 feet of limestone was exposed.

The last few years have inaugurated a new era in the history of the South African diamond deposits, inasmuch as rich bodies of diamantiferous ground have been located at great distances from localities which have previously been worked successfully. The group of which the Premier Mine is the best known member is the most striking example of this extension of area, but the centre of gravity of the diamond-mining industry seems to be gradually shifting northward, and the opening up of the interesting deposit of the Somabula Forest, so far north of any other known occurrence, foreshadows the development of an important branch of the industry in the Cinderella of the South African provinces, as Rhodesia has been not inaptly termed.

In view of the vigour with which the investigation of the English Chalk is at present being carried out by amateurs, resulting in the accumulation of large numbers of fossil specimens which give rise to difficulties of nomenclature, the publication of a key to aid collectors in determining the specific position of members of one of the largest Cretaceous genera of the phylum Polyzoa does not seem inappropriate.
