2a 



Park's first section (1905, p. 509, fig. 3) represents the soutliern limb 

 of a syncline (see fig. 2), and the second (lac. cit., p. 510, fig. 4) cuts 

 the northern limb of the same syncline at right angles. I have given my 

 own interpretation of this section in fig. 3, which represents the same line 

 of section as Park's section at Trig. T. 



The reference numbers of the beds in figs. 2 and 3 are the same 

 as those given by Park in his sections. This, perhaps, will facilitate a 

 comparison of the sections. 



S.W. 



Pig. 2. — Section along sea-cliff north of Kakanui. Distance = f mile. 1, calcareous 

 tuff, fossiliferous ; 2, blue micaceous tuff bed ; 3, limestone ; 3a, nodular band ; 

 4, sand ; 5, greensand ; 6, breccia. 



The lowest bed exposed near the quarry is a very calcareous tuf? (1), 

 which contains a considerable variety of fossils, but the latter are diffi- 

 cult to extricate owing to the great hardness of the rock. The following 

 forms were collected : *Turho marshalli Thomson, *TurriteUa carloftae 

 Watson, *Ejpitonium hrowni (Zittel), *E. rugulosum lyratum (Zittel), 

 *Siphonalia turrita Suter, *S. conoidea (Zittel), *S'. costata (Hutt.), Lapparia 

 sp., *Dentalium soliduvi Hutt., *Pecten polymorphoides Zittel, *P. aldin- 

 gensis Tate, *P. delicatnlus Hutt., Lima angidata Sow., Venericardia 

 difficilis var. henhami Thomson, *Chione meridionalis (Sow.), Aturia aus- 

 tralis McCoy, Aetheia gaidteri (Morris), *Hemithyris sp. nov., Terebratida 

 oamarutica Boehm, ^Terebratida sp. nov., TerebratuUna suessi (Hutt.), 

 *Neothyris sp. nov. 



Overlying the tuff is a less calcareous blue micaceous tuff bed (2) 

 about 14 ft. in thickness, from which I obtained the following, fossils : 

 Turbo marshalli Thomson, Turritella carlottae Watson, Dentalium solidum, 

 Hutt., Aetheia gaidteri (Morris), TerebratuUna oamarutica (Hutt.), *Tere- 

 bratula sp. nov., Pentacrinus sp. 



The limestone (3) is about 20 ft. thick, and very pure. It 'makes ex- 

 cellent material for the lime-kiln, but it is too hard for building purposes. 

 It is very fossiliferous in parts, and from the quarry near the road (Everett's 

 Quarry) the following species were identified : Attiria aiistralis McCoy, 

 Pecten aldingensis Tate, Venericardia sp., *ThecideUina hedleyi Thomson, 

 *Aetheia gaidteri (Morris), *Hemithyris sp. nov., ^Terebratida oamarutica 

 Boehm, TerebratuUna suessi (Hutt.), *Rhizothyris rhizoida (Hutt.), *Neo- 

 thyris sp. nov., Magella carinata Thomson, *Terebratella oamarutica Boehm, 

 *Mopsea hamiltoni Thomson. 



Towards the top the limestone becomes glauconitic and much less pure. 

 and at the surface the glauconite sand and the limestone are so much 

 intermingled that the bed assumes the concretionary — or, rather, nodular — 

 structure (3a) similar to the beds at All Day Bay. Some of the nodules 

 are brown, and are invariably covered with a thin, much darker, shining 

 brown veneer.f Fragments of minerals and small pieces of volcanic rock 

 occur in this nodular bed (3a). Fossils are abundant, but mainly as 



t Dr. Thomson informs me that Mr. B. C. Aston has determined this veneer ta 

 be phosphatic.
