The above list of 16 genera and 19 species shows the essen- 

 tially marine character of the fauna of this stage, and its close 

 connection with the Lower Carboniferous group. The most remark- 

 able, perhaps, of the whole series heads the list. Several portions 

 of individuals of this trilobite were discovered ; and this is probably 

 the first time its presence in the British Islands has been recorded 

 in beds higher than the Yoredale shales, in which it is found in 

 other parts of Ireland. In Morris's ' Catalogue of British Possils ' 

 it is placed in the Carboniferous Limestone both of England and 

 Ireland ; and its survival into the stage of the Lower Coal-measures 

 is another connecting link between the two formations. Further 

 on, it will be shown that it has been recognized by Prof. Bbmer in 

 beds of this stage in Silesia (p. 638). The Middle Coal-measures 

 contain Anihracosia (Unio), which has been observed by Mr. Hard- 

 man above the " Old Three-foot " coal.

The general section of this coal-basin resembles that of Kilkenny 

 and Carlow. The beds lie along a sharp synclinal fold the axis of* 

 which ranges in a N.E. direction, in the centre of which the highest 

 coal-seams occur. The district has been described by the officers of 

 the Geological Survey, Messrs. F. J. Foot and J. O'Kelly, and the 

 fossils by Mr. Baily. The shales overlying the lower coal (called 

 " Upper and Lower Grlengoole ''" seams) contain Aviculopecten, Mya-
