Oif THE CORRELATIONS OF THE " CURIOSITr-SHOP BED." 547 



41. On the Correlations of the " Citriositt-Shop Bed " in Canter- 

 bury, !N'ew Zealand. By Captain F. W. Hutton, F.G.S. 

 (Eead June 24, 1885.) 



The Eiver E-akaia, after leaving the mountains, flows in a south- 

 east direction across the Canterbury Plains. In cutting its way 

 down through the shingles and silts of these plains, it has come 

 across and exposed on its left bank a small patch of calcareous and 

 arenaceous rocks, which are so full of fossils as to have given the 

 name " Curiosity- Shop " to the locality. It is situated between five 

 and six miles below the bridge over the Eakaia Gorge. 



I visited the Curiosity- Shop in February 1873, and made the 

 accompanying section (fig. 1). All the exposed beds dip 20° E.S.E., 

 and they appeared to me to belong to a single series.

1. Eiver gravels : the upper part coarse shingle; the lower yellow sand and 

 small shingle. 



"1. G-rey soft sandstone. 



3 and 4. Calcareous sandstone, with green grains in the upper part, with ir- 

 regular layers and pockets of clay in the middle portion. (Fossils.) 



5. Brown soft sandstone. 



Mr. A. M'^Kay, of the Geological Survey, has given a detailed 

 description of these beds *, which I have embodied in the foUowing 

 Table :— 



1. Eiver-gravels. 



Pareora Series. 



2. Loose grey quartz sands, 15 feet thick, with a bed of badly 



preserved shells. 



Upper Eocene Series. 



3. Soft calcareous sandstone, 10 or 12 feet thick; in the 



upper part highly charged with glauconite ; passing 

 downwards into irregular beds of tufaceous clay.
