Gudex. — Succession of Tertiary Beds in Pareora District. 259 



parts of the section. About a mile farther down, however, the red sands 

 are seen in the cuttings made for the road that passes over the steep hill 

 on the left bank. 



The limestone yielded Epitonium lyratum (Zitt.), E. orowni (Zitt.), 

 Pachymagas sp., echinoderm spines and plates, and Pentacrinus stellatus 

 Hutt. 



From the blue clay lying only a few feet above the limestone I collected 

 TurriteUa concava Hutt.. Crcpidula gregaria Sow., Pplinices sp., Surcula 

 fusiformis (Hutt.), Dentalium mantelli Zitt., D. ecostatum T. W. Kirk, Malletia 

 austral is (Q. & G.), Pecten huttoni (Park), P. zitteli Hutt., Chiorte meridionalis 

 (Sow.). Chiorte chiloensis truncata Sut., Limopsis aurita (Brocchi), Corbula 

 canaliculate Hutt., Cochlodesma angasi (C. & F.) (?), and Pachymagas parhi 

 (Hutt,). 



Ford's, Fenn's, and PringWs. 



If we follow the road along the foothills, from Squire's Farm to White 

 Rock, we find that almost the only Tertiary beds exposed are the grits of 

 the coal series. Between Squire's Farm and the first tributary of Little 

 River, however, a marine sandstone is found in one of the road-cuttings, 

 and farther on there is a small outcrop of limestone on the left of the road. 

 This limestone lies close in against the greywacke, and its position is hard 

 to account for, unless it has been faulted down. 



From the sandstone I collected the following fossils : TurriteUa sym- 

 metrica Hutt., Ancilla australis (Sow.), Psammobia lineolata Gray, P. zelandica 

 Desh., Venericardia pseutes Sut., V. zelandica (Desh.) var., Macrocallista 

 assimilis (Hutt.), Modiolus dolichus Sut., and Cardium waitakiense Sut.
