casts, and identification has been rendered difficult. Tlie following forms 

 occurred : *Troc]ms conictis Hutt. ?, *Astraea sp. afi. stdcata (Martyn), *Turho 

 sp., *Cypraea ovulatella Tate, Eidhria media (Hutt.), *Olivella neozelanica 

 (Hutt.), *Lapparia corrugata (Hutt.) ?, *Carclimn sp. aff. C. hraclnjtomum 

 Suter, *Cardium sp., *Arca decussata (Smitli), '^Pecten polymorphoides Zittel, 

 *Lima jeffreysiana Tate, *L. angidata Sow., *L. lima (L.), Aetlieia gaidteri 

 (Morris), *'H.emithyris cf. H. squamosa Hutt., ^Terebratula sp. Mopsea 

 Jiamiltoni (Thomson) and Isis dactyla 'Ten. -Woods are very abundant here, 

 and they pass up into the overlying greensand (5). 



Bed 5 is of unknown thickness, as it is unconformably overlain by quartz 

 sand. It is a glauconitic foramimferal greensand, and is fossiliferous. 

 The species were : Epitonium, hroivni (Zittel), *Siphonalia nodosa (Martyn) ?, 

 Teredo lieapliyi Zittel, *Pecten delicatnlus Hutt., *P. polymorphoides Zittel, 

 *Lima angulata Sow., *L. bullata Born, Aetheia gaidteri (Morris), Tere- 

 bratidina suessi (Hutt.), *Pachy7nagas parhi (Hutt.), Isis dactyla Ten.- 

 Woods, Mopsea Jiamiltoni (Thomson). 



Bed 6, which underlies the limestone at the northern end of the beach 

 about due east of Trig. T, is a somewhat coarse calcareous mineral breccia. 

 In its upper portions it is interstratified with limestone bands, and lime- 

 stone occupies vertical cracks in the breccia forming dykes. These lime- 

 stone bands contain Terebratida oamarutica. The breccia itself in its upper 

 20 ft. is very fossiliferous, but there is a noticeable absence of brachiopods. 

 A collection included the following forms : Turbo marshalli Thomson, 

 Turritella carlottae Watson, Crepidula sp., *Polinices laevis (Hutt.) ?, *Cypraea 

 ovulatella Tate, Siphonalia turrita Suter?, *Siphonalia costata Hutt.?, Area 

 sp., *Glycimeris laticostata Q. & G., Pecten delicatnlus Hutt., *P. wil- 

 liamsoni Zittel?, P. hutchinsoni Hutt., *Lima sp. afi. angulata Sow., 

 L. jeffreysiana Tate, L. bullata (Born), *V enericardia australis Lamk., 

 *F. difflcdis Desh. var. benhami Thomson, *Diplodonta zelandica (Gray), 

 *Chione chiloensis truncata Suter, *C. crassa Q. & G., Dosinia caerulea 

 (Reeve), Cardium sp., *3Iesodesma subtriangulatum (Gray), Siphonium 

 planatum Suter.

 Park {loc. cit., iig. 4, p. 510). The reference numbers of the bads are the

The section runs E.-W., with a flattening dip to the sea. Bed 6 is the 

 mineral breccia which is exposed in the fields to the west of Trig T. The 

 limestone (7) on which the trig, station has been erected is the Waitaki 

 stone of Professor Park. This calcareous band can be traced as a continuous 

 ridge from the station to Kakanui Quarry in a southerly direction, and from 

 the quaiTy to the sea-beach.
