384 PKOCEEDINGS OF THE GEOLOGICAL SOCIETY. [May 10, 



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 expla- 

 nation. All loess need not be of river origin ; in oscillations of land 

 marine deposits must be 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 to- 

 gether 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 de- 

 posit 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 sub aerial. 



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.

1. On the Ancient Eocks of the St. David's Peomontoey, South 

 Wales, and their Fossil Contents. By Professor R. Hakkness,

 New Species, by H. Hicxs, Esq. 



(Plates XV. & XVI.) 



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 iden- 

 tical with P. Forchhammeri of the alum slates of Andrarum in 

 Scania." 



In the last edition of Siluria (1867) the same figure is named 

 Paradoxides Hiclcsii ; its locality is indicated as " near DolgeUy, 

 North Wales ;" and it is further stated that " this fossil has been
