What were formerly considered t6 be lower coal measure shales 

 are in the second edition of the Explanation to sheets 102 and 

 112 of the Geological Survey of Maps (1875), called "Upper 

 Shales," but as they contain a distinct and characteristic assem- 

 blage of fossils corresponding with those of the basal shales of the 

 coal measures of Kilkenny, Queen's County, Tipperary, Limerick 

 and Clare, the original designation is retained. Three distinct 

 patches of these basal shales occur in the north of Dublin, near 

 Garristown, the Naul and Westown, extending east of the '' Man- 

 of-War ;" a second at Featherbed-lane station, Baldongan ; and 

 the third on the sea-shore at Loughshinny, between Bush and 

 Skerries. The shales of these places are, in many instances, full 

 of fossils, mostly marine shells such, as Avicidopecteii yapyvaceus 

 Posidonomya Becheri and P. membranacea, Goniatites sphcericus 

 and Ortkoceras Steinhauerii. With these are occasionally asso- 

 ciated fish remains and a fey/ fragmentary stems of fossil plants. 

 At some of the localities junction-beds between these coal 

 measure shales and the limestone may be observed. -These 

 junction-beds in the list of species are marked with an asterisk
