(Judex. — Succession of Tertiary Beds in Paredra District. 257 



The crab-beds are well seen half-way up the hill on the left bank of 

 the tributary, and have their usual character. The concretions contain a 

 few crabs, while specimens of Cucullaea alia Sow., partly replaced by iron 

 compounds, are found scattered through the beds. The crab-beds may 

 be followed all along the Little River Valley, first on the left bank, then 

 in the bed of the river, and then along the right bank until the lime-kiln is 

 approached. One mile above the kiln the crab-beds are seen passing up into 

 marls of a greenish-grey colour. These are the " grey marls " described 

 by McKay. The same beds are seen in the left bank, above the bridge. 



YiG. 9. — Section along left bank of main tributary of Little River, above the 

 junction Distance, f mile ; direction, N.W.-S.E. ; dip. 10°. 1 . Trias-Jura. 

 2. Pipeclay. 3. White quartz grits, with carbonaceous shales. 4. Sands 

 with calcareous sandstone. 5. Crab- beds (greensands) with small con- 

 cretions. 6. Marls, grey at the top. 7. Limestone. 



The limestone forms the crown of the Craigmore Block, and appears 

 on Holme Station at a lower level. It exhibits folding at both ends of 

 Craigmore, where an anticlinal structure appears. At the north end, in 

 a section S.S.W.-N.N.E., the dip is 10° to the south-south-west; and still 

 farther on, in a section W.-E., the dip is 40° to the west ; while in a section 

 at the crest, running west and east, the dip is 0°. The eastern limb 

 has been almost completely shorn away by the action of Little River, 

 but the limestone on Holme Station and in Mount Horrible enables us to 

 reconstruct the anticline. At the south-west end of Craigmore the struc- 

 ture is not quite so clear, chiefly because the anticline dies away in the 

 next mile or two, and is followed by an unsymmetrical syncline in the 

 direction of Squire's Farm. 



There is a small, superficial fresh-water deposit on the left bank of Little 

 River, about two miles above the bridge, and from it I collected specimens 

 of a fresh-water gasteropod which Mr. Suter says is new. 



The lower red sands and sandstones yielded Polinices suturalis (Hutt.), 

 Typhis maccoyi T.-W.. Volutospina sp., Crassatellites obesus (A. Ad.), and 

 Astarte ? sp. 



From the crab-beds on the left bank I collected Struthiolaria tuberculata 

 Hutt., Ancilla hebera (Hutt.), Surcula fusiformis (Hutt.), Cucullaea alta 

 Sow., C. attenuata Hutt., Atrina zelandica (Gray), Ostrea sp., and Macro- 

 callista assimilis (Hutt.). 



From the upper crab-beds, one mile above the lime-kiln, I obtained 

 Turritella symmetrica Hutt., Polinices gibbosus (Hutt.), Ancilla sp. now, 

 Dentalium solidum Hutt., Crassatellites obesus (A. Ad.), Ostrea nelsoniana 

 Zitt., Gryphaea tarda Hutt., Pecten (Chlamys) williamsoni Zitt., P. hilli 

 Hutt., P. huttoni (Park), P. delicatulus Hutt., Pecten sp. nov. between 

 triphooki and zelandiae, Macrocallista assimilis (Hutt.), Teredo directa Hutt.. 

 Holaster sp., and Cidaris spines.
