To the south of the Teyrah river and west of that town, the surface 

 of the gently swelling ground is sheeted with a gravelly conglomeritie 

 sub-recent looking deposit of considerable thickness as seen in the ravines 

 towards the river bank. 



The junction between the NuUia sands and the shales beneath 

 was again observed in the river bank near Teyrah,

At a little distance to the north, these shales are more fossiliferous, 

 containing Ostrea, Pecten, Plamna, fragments of Balani, Bryozoa, 

 and smooth spines of Echinoderms. 



Further on lower beds appear, containing some gastropoda and in- 

 cluding a Turritella band. Below these are 20 feet of clays, and in 

 the bed of the next stream-course, they overlie a hard, yellow, marly 

 limestone, rough with fragments of oysters and small pectens. North 

 of this stream on a small rocky hill, brown, flaggy, impure, limestone 

 full of hollow casts of shell-fragments has an unusually high dip of 

 70" to S. 30° E., becoming rapidly less on the outcrop side of the hill. 



Open ground extends to near Kaunai, where dark-yellow shelly 

 limestones contain bryozoa and foraminifera with

 these is a considerable thickness of clays and shales containing many 

 fossils and a shelly conglomeritie band with bored clay nodules, pebbles
