162 LOWER OOLITIC BOCKS OF ENGLAND: 
Bnvford St. Michael), there are two small outliers which have 
been preserved, in consequence of the Inferior Oolite having 
been let down by faults. In the small outlier north of the River 
Svvere (Combe Hill), Prof. Judd found about 15 feet of white 
oolitic limestone, some of the beds being very shelly ; at the time 
of my visit only about half that thickness of rock was exposed. 
Many fossils have been collected from the beds, by Mr. Beesley, 
Mr. K. Gibbs, Prof. Judd, and Mr. Walford :* they include the 
following species : 
X Strophodus. X Perna rugosa, var. quadrata. 
X Ammonites Murchisonae. X Trigonia beesleyana. 
X Belemnites ellipticus. pullus. 
X Nautilus. Terebratula fimbria. 
X Natica cincta. globata. 
X Patella rugosa. X maxillata(submaxillata). 
Area Pratti. X perovalis. 
X Astarte elegans. plicata. 
X Hinnites abjectus. X G-aleolaria (Serpula) socialis. 
X Lima cardiiformis. X Pentacrinus Milleri. 
electra. (H. B. W.) X Pygaster semisulcatus. 
X pectiniformis. (H. B. W.) X Stomechinus germinans. 
Lucina Wrighti. X Montlivaltia trochoides. 
X Ostrea flabelloides. Thamnastraea defranciana. 
X Pecten lens. Thecosmilia Wrighti. 
X personatus. 
Those marked X occur also in the pit next mentioned. 
Prof. Judd also states that " On the south side of the River 
Swere, at a place known as Blackingrove, we find a pit opened in 
beds of stone similar to that on the other side of the river at 
Combe Hill ; as we go lower in the series, however, the oolitic 
limestones are seen passing down into beds of a more siliceous 
and shelly character, and finally into the hard siliceo-calcareous 
rock, which occurs so commonly in the Northampton Sand. The 
whole of these beds are crowded with shells which have been 
collected both by the late [Charles] Faulkner, of Deddington, 
and the officers of the Geological Survey ; thus we have been 
made acquainted with a very large and interesting fauna from 
this locality, which enables us to refer the beds without doubt to 
the base of the Inferior Oolite. The strata representing the 
Northampton Sand here, as at many other places, contain 
numerous rounded pebbles of argillaceous limestone ; it is in 
places banded with brown oxide of iron in its lower part, and 
rests directly upon the Upper Lias Clay." 
The following fossils have been collected at Blackingrove in the 
sandy limestone of the Northampton Sand : 
llesodon (Pycnodus). Belemnites aalensis. 
Strophodus. Gresslya peregrina. 
Ammonites corrugatus. Pholadomya fidicula. 
Murchisonse.
