142 ENTALOPHORA. 



Affinities. This is a typical young Entalophora, and is closely 

 allied to the Cretaceous E. clavata, D'Orb. 1 The two specimens 

 from the Richmond boring which Vine took as the type of his 

 var. pmtulopora of his E. richmondiensis, do not seem to me 

 related to that species. They agree exactly with the series of 

 specimens figured by Walford from the Shipton Gorge. E. clavata, 

 D'Orb., represents this type in the Cretaceous ; the zocecia in that 

 species have a ribbed ornamentation, instead of being punctate, 

 and none of the specimens figured show ooacia.
