Mr. Kingsmill as the quiet water sediments of a great gulf with the Miocene conglomerates and sandstones of Nanking and elsewhere for its marginal equivalents, appeared to require a different explanation. All loess need not he of river origin ; in oscillations of land marine deposits must he carried lip to great heights ; and, referring to Mr. H. M. Jenkins's determination of the marine origin of the Loess of Belgium, Prof. Jones thought it highly probable that some at least of that in China may have been similarly formed.
Mr. Hughes said that the author appeared to have grouped together all the superficial deposits of a vast area without explaining very clearly the grounds upon which he identified those deposits at distant points. He did not prove that what he called the shore deposit was marine, or that it was of the same age as the loam which he described, and which Mr. Hughes thought, from the description, was far more likely to be subaerial.
Mr. Evans and Mr. Etheridge suggested the probability of much of the so-called Loess having been brought down from higher loamy beds, possibly derived from the decomposition of limestone rocks containing sand and clay, and redeposited by the action of rain.

In an early edition of Siluria (1854) there is a figure of a specimen of Paradoxides Forchhammeri ? Angel., from the black slates of North Wales. In the third edition of the same work (1859) the same figure occurs, with the remark " locality unknown, probably from Pen Morfa, near Tremadoc, North Wales." In this edition there is also a note with reference to the occurrence of this form, stating that " only one species of Paradoxides has yet been found in Wales ; although the specimen is imperfect, Mr. Salter believes it to be identical with P. Forchhammeri of the alum slates of Andrarum in Scania."
In the last edition of Siluria (1867) the same figure is named Paradoxides Hicksii ; its locality is indicated as " near Dolgelly, North Wales ;" and it is further stated that " this fossil has been
