^^^ PAPBUS, ETC. 



DiSCINA IIUMPHREYSIANA, Sowerby. 



This species has hitherto beeii found only in tlie Kim- 

 meridge Claj. It may be desirable to record its presence 

 m the Coral Ea- of Lyneham, Avlierc it is abundant. 



Rhynciionella spinosa, Schlotheim. 

 In the Cotteswold and other Iower oolites this shell has 

 been supposed to indicate a partlcular zone. Althoiigh it 

 is therein especially abundant, it is by no means con°fined 

 to it. I have obtained the species from the Fuller's Earth, 

 near Eatli, and also in the Bradford Clay. Some very 

 dwarfed or young forms of it are to be found in the upper 

 beds of the Inferior Oolite of Duudry. 



Terebhatula carinata, Lamarck. 

 This sliell has hitherto been found only in the Inferior 

 Oolite. Some speciraens smaller than the type-form are to 

 be found in the coralline bed of Ilampton ClifFs, which I 

 am unable to distingulsh from this species. 



In addition to the Brachiopoda noticed in this paper, I 

 am possessed of various niinute specimcns, which difFer 

 from any described species. Some of these may be the 

 young of Brachiopoda that occur in the beds in which they 

 are found; but until their passages into adult shells can be 

 satisfactorily recognised, it will be undeslrable lo figure or 

 describe them. Three examples of well marked and per- 

 sistent forms are provisionally named and given below.
