424 MR. A. W. WATERS ON THE RELATIONSHIPS 



CoNESCHARELLINA EOCCENA. Neviani. 



Conescharellina eocccna, Neviani, " Bri. Eoc. del Calcare mimnmlitico di Mosciano presso 

 Firenze," Bol. Soc. Geol. Ital. vol, xiv. p. 122 ((.'.) fig. 5 (189.")); Waters, " Batopora," p. 85, 

 pi. 6. figs. 8, 12 (1919). 



Batopora conica, Segiienza, "Form. Tevz." p. 42, pi. 4. fig. 10 (1879). 



Batopora conica, Hantken (non Haswell). 



This at first was taken for Batopora, but the shape of the cone is the same 

 as in various Oonescharellinse, while sections show its relationship, as the 

 interior of the cone is filled in by chambers longer in the direction of a line 

 from the apex to the base (fig. 8, loc. cit.). The zooecia. are in irregular 

 longitudinal lines, and are hexagonal or round, with large pores between 

 the neighbouring zooecia. The visible aperture, which is probably only the 

 secondary aperture, is round or oval. Near the apex of the zoarium there are 

 only small openings with a larger one at the apex, though this is smaller 

 than the pits of SpJueropora and Batopora. On ether Conescharellina I have 

 often seen small openings in the secondary growth over the apex, but 

 have never found a central pit. The base of the zoarium shows large pores 

 much like those of C. conica, Haswell (PI. 29. fig. 20). The ovicell is wide, 

 slightly raised, and only occurs near the base of the zoarium. 



This seems to be the only species of Conescliarellina known from the 

 Italian tertiaries, and in some respects it varies from most Conescharellinse. 



Hantken has frequently mentioned Batopora conica, Hantk.; but attempts 

 made by various people to find where he has described it have failed, and 

 I have in vain looked through most of his papers. Finding specimens 

 presented by Hantken in the British Museum (B. 3724), is therefore most 

 interesting. It is conical, about 5 mm. high, there is considerable swelling 

 at the apex, and one of these shows a hollow surrounded by very small pores, 

 with larger ones over the rest of the swelling. The zooecia have a nearly 

 round aperture and smaller openings round them. One specimen is cut 

 longitudinally through the middle, showing the cancellate structure, just as 

 in my figure 8, loc. cit. The preparation referred to was no doubt made by 

 Hantken.
