present writer were examining the glacial features of Inman 

 Valley, opportunity was found to visit the outcrop from whence 

 this interesting specimen had been obtained, with the result that 

 Archoeocyathince remains were discovered in the associated marbles. 

 Prof. David was the first to recognise their occurrence on the 

 weathered surface of the stone, and when once noted additional 

 examples were soon found. 



The locality where these remains were discovered is about three 

 miles north of the Normanville Hotel, in a valley opening out to 

 the sea, from which it is distant about half a mile. The place is 

 easily fixed by the old Wheal Mary silver-lead mine, several dis- 

 used shafts being on the immediate ground where the fossils were 

 first discovered. The fossils are not very plentiful, so far as 

 could be judged from the weathered surfaces of the limestone, 

 and appear to run in narrow fossiliferous zones in the direction 

 of the line of strike, such zones being repeated over a consider- 

 able width of outcrop. One of these coralline belts crosses the 

 valley obliquely, passing very near one of the old mining shafts. 



At Easter T was able to make a second visit to the spot when 

 the fossiliferous belt was followed along a parallel line to previous 

 observations, still further to the north-west, passing through the 

 next lateral valley for a distance of a quarter of a mile when it 

 was lost to view beneath a thick crust of travertine which 

 covered the crest of the hill. 



The fossiliferous beds form part of a very thick series of 

 marbles, limestones, and calcareous shales which exhibit a close 

 stratigraphical and lithological correspondence with the Sellick's 

 Hill beds, to be referred to presently. Their outcrops form steep 

 and rugged hills with only a slight amount of soil on their pre- 

 cipitous sides. The most characteristic lithological feature is a 

 grey streaky cryptocrystalline marble which occasionally changes 

 into a coal-black variety, and more rarely to a mottled red colour. 

 Strings of arenaceous and ferruginous material more or less pene- 

 trate the limestones in irregular reticulating lines which stand in 

 relief on the weathered surfaces. This heterogeneity of composi- 

 tion is unfortunate, in that it detracts from the value of the 

 marble as an ornamental stone. The Archceocyathince are found 

 in the grey marble, and are often difficult to distinguish from the 

 matrix in which they are imbedded. It is highly probable that 

 in some portions of the stone the organic remains have been 

 obliterated by the metamorphic action that has converted the 

 limestone into marble. The fossils occur in every stage of de- 

 finiteness, and in many cases only the faintest evidences of 

 organic structure has been preserved, the outlines shading off into 

 the amorphous matrix. 



The beds show a high angle of dip. In the Wheal Mary shaft, 

 as seen from the surface, the dip reading was 65° W. 5° S. About
