place called Cerwynddu, about half a mile we^t of the town, on the banks of 

 the Iifon, some very rare sijeciinens for this district have recently been 

 found by Mr. David Griffith. One very large fossil, which some gentlemen 

 supposed to be the end of an 0/ thoceratite flixttened, and others a Discina, 

 was marked "unknown," nor coiilj it be defined. There was also one other 

 marked "unknown," which was much admired. The spot where these latter 

 fossils were found is one of the most picturesque spots in the district, well 

 worthy of an artist's visit. About a mUe and a half west of Builth, where the 

 Central Wales Railway runs, some most interesting fossils were found, which 

 give one some idea of the animals that formerly lived in that particular dis- 

 trict. Two Pteryyoti only, a fair number of Ptilodpciia lanceolata, and an 

 immense number of Orthciratites, have been found on this line. One of the 

 Pterygoti is named by Mr. Salter PUryyolas Jonesii, and the other as "a new 

 species." Mr. David Griffith was foi tuiiate enough to find both those speci- 

 mens. There was a specimen of GraplolUes iudensis, the second ever found in 

 this district, from the Volcanic giit, on the tray, which Mr. John Jones, of 

 Builth, handed roimd for inspection. In the Llandilo flag, the best Calymene 

 duplicata was banded for inspection by Mr. Powell, as was also a very fine 

 Honialonotus Kniyhtii, found near Erwd village in the Upper Ludlow, and 

 one specimen only of the Spongarium Edwardsii, a very rare fossil indeed. 

 There were numerous other different specimens exhibited, but space and time 

 prevents our being able to do justice to them.
