conglomerate of red and white quartz, imbedded in the sandstone, 

 again occurs. 



The yellow, or Downton beds, are worked in a quarry on the 

 Lodge Farm, in the adjoining parish of Huntington, and contain 

 traces of Pterygotus and Pteraspis truncatus. 



A quarry, now abandoned, was some years since opened on New 

 Barn Farm, Kington, on the sloping ground on the southern side 

 of the Arrow. The surface-soil is not more than four feet above 

 the Ludlow rock. Among the refuse stones I found a portion of 

 Pterygotus, in a stone corresponding in composition with the lowest 

 beds at Bradnor Quarry, and Pteraspides in a micaceous sandstone. 

 The ground slopes abruptly from the quarry towards the river ; and on 

 the slope, some feet below the sandstone, the bone-bed, containing in 

 addition to the Molhisca before named, Theca Forbesii, is exposed. 



The similarity in appearance of the stone, of which the church 

 and many of the houses in New Radnor and its neighbourhood are 

 constructed, with the lowest Bradnor beds, induced me to examine 

 the quarry from which it was obtained. The road to this quarry pro- 

 ceeds from New Radnor to Harley, and then up a narrow valley by 

 the side of one of the streams which run from the Forest of Radnor to 

 the blue flag- or slate-quarry ; a steep road here skirts and gradually 

 ascends the hill on the opposite side of the valley. In the last steep 

 ascent, stones containing Chonetes lata, Orthoceras bullatum, and 

 other common forms of the Upper Ludlow rock, occur on the surface. 

 The sandstone- quarry is situated at a very considerable height, not 

 far from, and to the north-east of, the Trigonometrical Station. It 

 is a mere outlying patch of sandstone, reposing on the Ludlow rocks. 

 The yellow bed of sandstone alone occurs, — from 8 to 9 feet thick, 

 almost free from mica*, and with the surface of the beds coated 

 over with small crystals of quartz. The quarry has not been worked 

 for some years. In the refuse stone, Pterygotus and the small 

 Lingula occur. 



Between Shobdon and Mortimer's Cross on the side of the turn- 

 pike-road is a quarry, the lowest beds of which are Downton sand- 

 stone, similar in composition with, but rather more of a yellow tint 

 than, the same beds on Radnor Forest and Bradnor Hill. Lingula 

 cornea occurs in abundance, with occasional traces of Pterygotus in 

 the refuse stone of the Downton beds, the lowest bed of which was 

 not exposed when I visited the quarry. The layer of carbonized 

 vegetables is also present. 



At the bottom of the old red sandstones on the right bank of 

 the Teme, near Ludford, and opposite to the Paper Mills, is a thin 

 layer containing carbonized vegetables, lying immediately underneath 

 the old red sandstone and on a bed of bluish-white marl. In this 

 layer Mr. Lightbody and myself found spines of Leptocheles and a 

 Fish-bone f, about three inches in length and a quarter of an inch in 



* The grains of mica are very minute and apparently enter but little into the 

 composition of these beds. 



t Prof. Huxley has examined this, and believes it to be either the jaw or tooth 

 of a Chimseroid ? Fish.
