A Mongst the fossils collected from the Pendleside Limestone of Butterhaw Knoll, Cracoe, Yorkshire,inwhich Cyphaspis acanthina. (Coignou) was discovered a few years ago, there are in the Woodwardian Museum a few specimens of a species of Phillipsia, which were foundin1889 by Professor Hughes' same geological party. My attention has been recently directed to them, and it has become evident, after a careful examination, that they do not belong to any of the hitherto described species of this genus.

Though the kind intervention of Professor H. G. Seeley, F.R.S., some few years since, Mr. Percy Hawkins was induced to present to the Geological Department of the British Museum a slab of Old Red Sandstone from Llanvaches, nearly midway between Caerleon and Chepstow, Monmouthshire, containing some excellent impressions of Archanodon Jukesi.

The name Ammonites euomphalus was given by Sharpe to an imperfect though unique specimen from the Lower Chalk, Man of War Cove, on the coast of Dorset. This example (according to Sharpe) originally belonged to E. H. Bunbury, Esq., but now forms part of the British Museum Collection [No. 50,158].

When studying the Dartmoor Rocks some years ago I was anxious to ascertain whether any fragments referable to Dartmoor could be detected in the Culm conglomerates and Culm sandstones of South Devon. Sections cut from these rocks, collected for me by my friend Mr. W. A. E. Ussher, F.G.S., proved in every way so dissimilar from Dartmoor rocks and minerals that further investigation in that direction appeared useless. About the same time I collected a variety of fragments from the New Red breccia at Labrador, near Teignmouth, while Mr. Ussher supplied me from other localities. These, again, even when schorlaceous, differed so much from any rocks known to me that I postponed further inquiry in that direction also sine die.

Cases of relatively recent change in the courses of rivers, due to the invasion of their valleys by neighbouring and more rapidly working streams and the consequent diversion of their waters, have been investigated of late years by an increasing number of geologists in different countries. Such phenomena are, of course, most frequent in mountain districts, and the Swiss Alps have yielded many examples of greater or less certainty. Some cases are evident and undeniable; others are difficult to decide upon, and need careful consideration of all available evidence; while in yet other instances it is possible that statements as to the occurrence of such changes have been accepted on inadequate authority. The generally received opinion as to the present and past relationship of the Landwasser and the Landquart can certainly not be included in the last category, but neither can it, I think, be rightly placed in the first.
