1. Polyzoa and Anthosoa from the Upper Cretaceous Limestone of 

 Need's Camp, Buffalo River. By W. D. LANG, M.A., F.G.S., 

 British Museum (Natural History). 



Plate I. 



THE rock containing the Polyzoa here described, is so full of them 

 in places that they compose the rock nearly to the exclusion of 

 its other components. Such pieces closely resemble in general ap- 

 pearance specimens of a rock composed mainly of Polyzoa from the 

 Dariian of Paxoe, in the island of Seeland, Denmark. Moreover, in 

 both rocks the surfaces of the specimens are very ill-preserved, 

 being rough, with the details ill-defined, as though the specimens 

 were covered with a thin incrustation. And in both the large 

 proportion of erect, cylindrical Polyzoa is remarkable. 



The species described below range from the Neocomian to the 

 Danian, and the majority are restricted to the Chalk. In so far 

 as it is possible to assign a definite horizon to the deposit on the 

 evidence of the Cyclostome Polyzoa only, it appears that its age is 

 Senonian or Danian. 



DIASTOPOBnm 



GENUS FILISPAESA, d'Orbigny. 



Gregory :;: places this genus among the Diastoporidae because of 

 its resemblance to Proboscina. He says it may be regarded as 

 " a group of ProboscincB with an erect habit " ; and goes on to show 

 how some species of Filisparsa correspond with some of Proboscina. 

 But he also points out that Pergens t placed the genus in the 

 Idmoneidae. The nature of the zoarium and distribution of the 

 zooecia are such that the genus occupies an intermediate place
