This paper opens with a critical account of previous research 

 among the Carboniferous rocks of North Wales, chiefly the work of 

 the late G. H. Morton, Mr. K, Kidston, and Mr. A.Strahan. There 

 follows a detailed account of the various beds, exposed in numerous 

 quarries worked for road-metal, iron-manufacture, lime, cement, 

 chert, or building-stone. Fossil-lists are given from each exposure 

 of importance. The lower series of the Carboniferous Limestone, 

 OS dtvek)ped in the Bristol area, was never deposited in this district, 

 where the lowest beds contain fossils characteristic of a compara- 

 tively-late phase of the Carboniferous-Limestone Period. "Whether 

 tliis was due to irregular configuration of the ocean-floor of Vixat 

 age, or to contemporaneous earth-movement of a regional character, 

 cannot as yet be deteimined. The base of the Limestone is cha- 

 racterized by Dui'ieaieUa ( Prodvctus) llanr/ollensis, and appears to 

 correspond with the junction of the Upper Seminnla- and Lower 

 lJiliu)Wi>Jii/Uum-Bods of the Bristol area. The next limestones in 

 ascending succession are characterized by the presence of Uibuno- 

 jihi/llnm i)> and Ci/((thoj)hj/llum Miorhisoiu, fossils which indicate, in 

 the Bristol area, the life- zone wliich immediately underlies the 

 Lonsihilia-Beih. Tlieso two life-zones have been named by 

 Dr. Vaughan the Lower and Uj)per DihiDiajJii/Ihim-Zones respec- 

 tively. The C(/ti(?iaaonia-Bc(ls and the cherts are equivalent to 

 a zone higher than the Upper JJibwio/ihi/Uuin-Zono of Bristol, 

 and not represented there. The black limestones (containing 

 I'osidonowya Buheri) with shales, at Teilia, Holywell, and 

 near llagillt, which occur above the cherts, are the honiotaxial 

 equivalents of the Pendleside Series. These beds are followed by 

 the Gwespyr Sandstone, which is correlated with the ^lillstone 

 Grit. A range-table is given of the chief brachiopods and corals, 

 and the paUrontological sequence is comjiared with that occurring 

 at Bristol and in the North of England. A few notes on the 

 ])ala'ontology conclude the ])apcr, and Dr. 11. II. Traquair ai)pends 

 a short description of a new species of Elonichtlnjs, occurring in the 

 Holywell Sliales.
