I learn also from Lieut. Weller and Capt. Sheppard, of the R.A., that they have found the 

 following organic remains in the carboniferous limestone of the county of Clare, namely, north 

 of the Shannon, at the distance of three and five miles respectively from the city of Limerick: 

 Trilobites, Orthoceratites, Pleurorhynchus hibernicus, Spiriferae, Productae, Euomphalus, and Re- 

 tepora, with several species ofCrinoidea, the Ampullaria helicoides, and aNatica; and in the lime- 

 stone south of the Shannon, near Limerick, also a few specimens of univalve shells. Of the Trilo- 

 bites, the post-abdominal portions of six individuals only were met with, which belong to two spe- 

 cies ; one of which appears to be new or undescribed, and the other to bear some affinity to the 

 Trilobite figured by Martin under the name oi Entomo/ithus oniscites, in tab. 45*, fig. 1.' 



Coal Formation. 



(58.) The South Munster coal tract occupies a large area, computed to 

 contain nearly one thousand square miles ; yet the seams of coal which have 

 been met with, are comparatively few in number and importance. Nor is 

 it hkely that many exist, for the elevated position of the coal-field above the
