Hythe beds, (Meyer) to the Bargate stone inclusive, (the whole 

 being contained in the Hythe beds of H.M. Geological Survey.) 



Each particular horizon in this series has however not been 

 recognised at Upware and Brickhill, perhaps because of the un- 

 fortunate mixture of the fossils in the course of the workings ; but 

 we still have some evidence in the large blocks preserved in the 

 Woodwardian Museum which shews that Terehratula sella (var. 

 Upwarensis) was especially abundant in the lower phosphate bed, 

 just as at Godalming it occurs in the Hythe beds and lower clays 

 only. Other species from this conglomerate are, 



Terehratella Fittoni, Meyer. Terehratula depressa, Lam. 



Terehratula Moutoniana, d'Arch. ,, prcBlonga, Shy. 



„ microtrema, Walker. Pecten orhicularis. Shy., 



and many of the Lamellibranchs and Gasteropodes. 



Further comparisons with more distant localities of the Vectian 

 area yield results in perfect conformity with our conclusions from 

 the Godalming area. In the Isle of Wight, amid the rich profusion 

 of fossils found in the Atherfield beds, only 15 species occur in 

 our Neocomian phosphatic series, and of these three only, namely, 

 Lima Farringdonensis and the two sea urchins Pseudodiadema 

 Fittoni and Peltastes Wrightii, belong to our particular Ironsand 

 types. The 16 species common to the Upware bed and the Shank- 

 lin sands present a much greater proportion with respect to the 

 whole faunas and form a much more weighty evidence of affinity. 

 They include the 4 Brachiopods Terehratella ohlonga, Waldheimia 

 celtica^ W. tamarindus and W. Wanhlyni. 



Again in East Kent we have the Hythe beds and Folkestone 

 series well exposed, the former shewing in its contained fossils im- 

 portant relationship to the Upware and Brickhill beds. 



Fifteen species of the Hythe Invertebrate fossils are also 

 common to Upware, amongst which are 



Ammonites Cornuelianus. Terehratula Moutoniana. 



Ancyloceras Fittoni. Waldheimia tamarindus. 



Plicatula C arteroniana. Peltastes Wrightii. 



Thus we find that the affinity of the Ironsand and Phosphatic 

 series is not with the mammillaris zone nor with any part of the 

 Folkestone series (H. M. Geol. Survey), nor do they belong to the
