upper part of the series. North Devon is then described, so far 

 as concerns the area south of Pickwell Down, which region is occu- 

 pied by the Upper Old Red and Devonian rocks ; these are com- 

 pared with the South "Wales beds. The Petherwin and Land-lake 

 series are carefully noted, and their position below the Marwood, 

 Pilton, and Barnstaple group established. Mr. Salter then notices 

 the Old Eed Sandstone of Somersetshire, Gloucestershire, and Shrop- 

 shire, adding important matter relative to the South of Ireland, as 

 regards the Carboniferous slate and the Coomhola series. The " Fo- 

 reign Equivalents " of the Upper Devonian, with the results of his 

 investigations, conclude this paper.

 Explanations of sheets 187, 192, 195, 196, 199, &c., with Palseon- 

 tological JN'otes by W. H. Baily, E.G.S., &c." It is unnecessary to 

 do more than mention that in the concise description of the country 

 to which these " Explanations " refer, much valuable matter is con- 

 tained relative to the Old Red Sandstone and Carboniferous beds of 

 the South of Ireland; and in them (especially the memoirs upon sheets 

 no. 187, 195, and 196 of those above enumerated) are embodied 

 the views held by Prof. Jukes relative to the two formations, which 

 are reproduced in his paper upon l^orth Devon and Rhenish 

 Prussia *, and also in his paper on the same subject in the Quar- 

 terly Journal of the Geological Society f.

 the Pilton, Petherwin, and IN'ewton-Bushel species, apart from theo- 

 retical views, and from the determinations of the Devonian and Car- 

 boniferous species, and as part of the literature of the Devonian 

 series, may be consulted : its value must be determined by the reader, 

 after careful and critical examination. 



1865. Jukes. — " Notes for a Comparison between the Rocks of the 

 South- West of Ireland and those of Worth Devon, and of Rhenish 

 Prussia in the neighbourhood of Coblentz " §, This paper is a resume 

 of the two previously noticed, to which is added an account of the 

 author's researches in Rhenish Prussia, chiefly in the neighbour- 

 hood of Coblentz. The South-Irish beds are briefly described here, 

 followed by a statement of Professor Jukes's idea of the contempo- 

 raneity of the Carboniferous Slate and Carboniferous Limestone. 

 North Devon is then cursorily noticed, especially Baggy, Croyde, 

 Braunton, and Pilton. The Middle or Ilfracombe beds receive a 

 passing notice only. Comparative lists of fossils from Ireland and 

 North Devon are given from different localities ||, followed by those
