NOETH-ITALIAN BETOZOA. 25 



is sometimes a calcareous basal attachment ; but in the stouter 

 forms I have seen nothing to indicate how it is attached. In some 

 specimens a calcareous disk forms a closure over the aperture ; and 

 from this calcareous growth a tubule rises up in the middle 

 (figs. 2 & 15). 



A closure with a tubule occurs in several Cyclostomata, as in 

 Diastoi^ora, &c. ; but I had always looked upon a closure of this 

 kind as confined to the Cyclostomata, whereas we now find it in 

 P. coronaia and Lepralia syringopora. 



There are a number of slender specimens (fig. 5) in which the 

 proximal part of the peristome is often raised ; and this appears to 

 me like the Cellaria labrosa of Eeuss (Eoss. Polyp. Wien. Tert. 

 pi. vii. fig. 38) ; but E,euss seems subsequently to have considered 

 that this figure represented Porina duplicata.

Most of the specimens in my collection have the zoarium in the 

 E. duplicata shape ; but, according to our present ideas, there is no 

 reason for separating this from E. Jieterostoma. 



At the side of the peristomatal aperture there is a large triangular 

 avicularium, forming a part of the peristome. The ovicell is 

 recumbent, not much raised, or subimmersed. We are not yet 

 acquainted with the oral aperture of this species ; but Kirkpatrick 

 has shown that Gigantopora lyiicoides has a Schizoporellidan 

 aperture. The large peristomial pore occurs in Gigantopora lyn- 

 coides, Eidley*, Hippotlioa fenestrata, Smittfj and Porina (?) colura- 

 nata, Waters J, and cannot be looked upon as a good generic 

 character.
