24. Planoebis MAEGiNATrrs, Drap. 



Flanorlis complanatus, Linn. : S. V. "Wood, Crag Moll., vol. i, p. 9, 

 pi. i, fig. 10. 



Form, and Loc. — Red Crag : Butley. Norwich Crag : T^orwicli ; 

 Bramerton Common ; Blake's Pit, 15 ramerton ; Southwold ; Bulchamp ; 

 Coltishall. 



This species has heen found in three pits at Butley, viz. : the 

 IS'eutral Parm pit, commonly known as the Oyster pit, the pit near 

 Butley Mill, and another on Butley Common. All the examples we 

 have seen are immature. It has heen recorded from the lower 

 pliocene of France ^ (Molasse d'eau douce du Lyonnais et du Dauphine). 



25. Planoebis spihoebis (Linn.), 



Flanorlis spirorlis, Linn. : S. V. "Wood, Crag Moll., vol. i, p. 9, pi. i, 

 fig. 11. 



Form, and Log. — Eed Crag : Butley ; Hollesley. Norwich Crag : 

 Norwich ; Bramerton Common and Blake's Pit, Bramerton ; Bulchamp 

 (S. V. Wood). 



This is a common pleistocene fossil in this country, not only in 

 the upper beds hut also in the lower (Forest Bed). On the continent 

 its earliest record is from the middle pleistocene of Cannstadt and 

 "Weimar. 



26. Paludesteina stagnalis (Bast.). 



Faludestrina ulvm, Penn. : S. V. Wood, Crag Moll., vol. i, p. 109, and 

 Suppt. I, p. 71, pi. iv, fig. 23 (as Hydrohia ulvce). 



Hydrohia ulv<^, Penn. : J. Gwyn Jeffreys, • Quart. Journ. Geol. Soc, 

 vol. xxvii (1871), p. 490. 



Form, and Loc. — Red Crag : "Walton (A. Bell). Norwich Crag : 

 Norwich ; Aldeby ; Thorpe, near Aldehurgh ; Yarn Hill ; Bramerton 

 Common ; Beccles ; and Dunwich. 



The examples from Gedgrave (see Crag Moll., vol. i, p. 109) are 

 certainly post-pliocene in age, and cannot he considered as of Coralline 

 Crag age. The species is very abundant at Thorpe, Aldeburgh, and is 

 by far the commonest shell of the genus in the English pliocene beds. 

 The earliest record from elsewhere than in this country, that we have 

 been able to trace, is from the lower pliocene (Congeria Beds) at 

 Mauer near Yienna, and Bizenz in Moravia. 



27. Paltjdesteina venteosa (Mont.). 



Faludestrina sulumlilicata, Mont. : S. Y. Wood, Crag Moll., vol. i,
