Craigmore. 



At the north end of Craigmore there is an exposure of the whole series 

 of Tertiaries from the quartz grits to the limestone. The grits are resting 

 on the Mesozoic rocks, which have been cut down to a dej)th of about 

 300 ft. by the Pareora River. The marine sandstones, as usual, contain layers 

 of Cardium waitakiense Sut. and Venericardia zelandica (Desh.) var. The 

 limestone which forms the crest of Craigmore occupies the summit of an 

 anticline, which pitches west to form the Upper Pareora basin. From the 

 limestone I collected Epitonium lyratum (Zitt.), E. browni (Zitt.), Pecten 

 huttoni (Park), Lima laevigata Hutt., Aetheia gualteri (Morris), Terebratulina 

 suessi Hutt., Rhizothyris rhizoida (Hutt.), Liothyrella landonensis Thomson, 

 Pachymagas parki (Hutt.), Flabellum radians T.-W., F. circulare T.-W., 

 Retepora sp., Graphularia sp., Eupatagus tuberculatus Zitt., E. greyi Hutt., 

 Pericosmus lyoni Tate, P. compressus McCoy, Pentacrinus stellatus Hutt., 

 Oxyrhina grandis Davis, Lamna huttoni Davis, L. incurva Davis, and Keke- 

 nodon (?). 



Tycho Valley. 



Along the right bank of this valley there is a steep limestone slope, and 

 in one place this is overlain by a deposit of blue clay, which is the only 

 evidence that all this limestone was once covered by the blue clay. From 

 the clay I collected Chione meridionalis (Sow.), Crassatellites obesus (A. Ad.), 

 and Limopsis aurita (Brocchi). 



Holme Station. 

 In this locality the upper red sands and sandstones are seen dipping- 

 south-east at 15°. The lowest beds have few fossils, but the upper beds 

 contain concretions and hard calcareous layers, as at Southburn Cutting 

 and Gordon's Valley. They contain a rich fauna, and it is noteworthy 

 that this is the exposure from which the first " Pareora " fossils were 

 collected. I collected here the sixty-nine species of molluscs tabulated 

 in column 13 of the table. 



Cannington. 



The only Tertiary beds exposed here are the limestone, the blue clay, 

 and the upper red sands. The section is noteworthy, as the beds dip into 

 instead of away from the Trias-Jura rocks. The limestone is well seen 

 on the right bank, where it dips in one section to the north-north-east at 

 40°, and in another section to the north-north-west at 10°.

On the left bank the limestone is followed conformably by blue clays, 

 as at^Squire's Farm, but heavy deposits of gravel have obscured the upper
