178 IfOTES Olf THE LIAS IN THE NEIGHBOURHOOD OF EADSTOCK. 



little attention to palaeontology ; there would have been little 

 difficulty in drawing the lines if the sections had been properly 

 studied. This fusion is continued throughout the district. 



"We may now pass to the quarry at Mungar which at one time 

 was so rich in fossils. Unfortunately it is not worked for road- 

 stone now, and the lower beds arg covered up with refuse and 

 clay. AU that is to be seen at present is about 8ft. of the M. Lias, 

 brownish-white oolitic limestones with some that are greyish and 

 hard, particularly in the heart of the stone. The beds are thick 

 and break irregularly. "We do not see the base, but the bed (e) 

 must be present as fragments of it are lying about. We are told 

 by those who have seen the beds exposed, that there are a few 

 feet of L. Lias and then the "White Lias. It was the latter that 

 was used for the roads, and the trollies of stone were run out 

 through the arched way that is now partly closed up. Close to 

 the top of the quarry is found abundantly A. Maugenesti 

 (and var. Valdani), also A. Menleyi and fiiiihriatus occur at the 

 same level. A. Jamesoni seems to occur throughout. We also 

 have A. ibex and hrevispina; Belemnites are very abundant, but 

 not very easy to extract entire ; those in my collection I attribute 

 to Belemnites paxillosus and apicicurvatus. Of Brachiopoda, 

 Rhynchonella rimosa and furcillata are fairly abundant. Other 

 fossils are Astarte, Inoeeramus ventricosus, Pholadomya ambigua, 

 Pleuratomaria expansa. Littorinae and other minute Gasteropods 

 are to be found in a beautiful state of preservation — we have only 

 a few in our possession. These beds represent the lower zones 

 of the M. Lias, and perhaps the upper zones may be unrepresented j 

 yet I foand one specimen which I take to be ^. spinatus^ it has 

 all the characters of that species except the serrations on the keel, 

 — its imperfect state in that quarter prevents any confidence in 

 its determination. 



A few hundred yards north of the Mungar quarry is a brick- 

 yard in which a considerable thickness of blue clay is seen. 

 The top 10 feet are brownish and blue clays, the lower 8 feet a 

 dark blue stiff clay. Nodules of argillaceous Iron-ore are
