The shelly limestone, bed No. 7, underlying the Awamoa 

 sandstones, contains large numbers of Turritella caversham- 

 ensis, as well as examples of Scaphella yacifica, Lima paleata, 

 Ostrea angasi, and Flabellum radians. 



From the greensands, bed No. 6, which evidently repre- 

 sent the Hutchinson quarry horizon, I collected from the 

 lower part especially Magellania novara, Mageilania parki, and 

 Bouchardia elongata. 



The yellowish-green tuff bed contains a number of small 

 shells, including representatives of the genera Diplodonta, 

 Venericardia, &c, mostly too minute for identification. Pos- 

 sibly the majority of them are new species. 



The Oamaru building-stone is represented by two beds — 

 namely, beds Nos. 2 and 4 — which are separated by a thin 

 stratum of dark bluish-green sandstone. These beds are com- 

 posed principally of comminuted corals and Foraminifera, but 

 the higher part of the upper band contains, besides these, a 

 good many littoral shells, among which I collected the follow-

The higher part of the upper band also contains fragments 

 of volcanic ash. The lower band is quite free from volcanic 

 matter and from large shells, and, being of even texture and 

 colour, furnishes the highest quality of building-stone quarried 

 near Oamaru. The upper band is not so uniform in texture, 

 is variable in colour, often containing streaks of a deep-yellow 

 colour, and is in consequence regarded as of inferior quality. 



Teschemaker's. 



There are two bands of limestone at this place, separated 

 by a few feet of fossiliferous tuff. They are well exposed in 

 the old quarry near the crown of the hill overlooking the 

 railway-line. The upper limestone is the typical clean pale
