This species is well known in nearly all washings from the 

 Cretaceous beds, and has occurred in the Cenomanian of 

 Bohemia. It is abundantly represented in the Cambridge 

 Greensand of Swaffham by slender stoloniferous fragments 

 and bulbous and bifurcated portions.

This form was originally described from the Cambridge 

 Greensand under the generic name Webbina as recorded by 

 Sollas and Vine. It has since been found in the Middle 

 Marl of New Jersey, in the Gault of Folkestone, and in the 

 lowest beds of the Chalk strata. 



One specimen of Vitriwebbina Icevis attached to a glauco- 

 nitic fragment was found in the washings from Swaffham.
