The number of eminent living geologists surviving since the days of De la Beohe and Ramsay and the beginnings of the Geological Survey must indeed be very few, but in Dr. A. R. C. Selvvyn, the subject of this brief notice, we have a living illustration of one of those active and energetic early workers whose labours have extended from Britain to Australia and Canada, and who, after half a century of active service in the field, is now enjoying his well-merited repose in British Columbia, “the land of the far West.”

To appreciate more fully Professor Hull's interesting paper “On the Submerged Terraces and River Valleys bordering the Britisli Isles,” it is necessary to refer to the Transactions of the Victoria Institute,inwhich the paper is illustrated by a map showing the contour-lines and soundings. The author thinks that the steep descent from the surface of the 100-fathom plateau to the abyssal floor of the Atlantic is analogous to an escarpment, instancing the Cotteswold Hills and other examples, and argues from this that the steep descent in question has been due to the forces of subaerial denudation, and has had a terrestrial origin.

Some years ago I received a fossil preserved in pyrites from the Gaskohle at Nyřan. No details could be seen under the microscope, and I was not sure if it were a Limulus or a seed. At an exhibition by Architects held last year at Prague I saw a specimen of a similar fossil with two of its appendages preserved, and I was fortunate enough to acquire the same for our Museum. I then reexamined all my material previously collected, and found appendages in other specimens also.

On May 14th, 1898, a party of the Geologists' Association visited Ayot under the direction of Messrs. John Hopkinson, F.G.S., and A. E. Salter, B.Sc, F.G.S. An account of the excursion will be found in the Proceedings of the Association, vol. xv, p. 308, and I think the following additional note of one of the sections visited will be of interest.

The subjoined list of characteristic genera of Mammalia has been compiled, at the request of my friend Dr. Henry Woodward, for the purpose of being used as a descriptive Table to be fixed on the wall of the Mammalian Gallery in the Geological Department of the British Museum (Natural History), and has been arranged in the form which was thought to be most suitable for the purpose.
