A MONOGRAPH OF THE TERTIARY POLTZOA OF VICTORIA. 105 



1. T. cereoides, Ellis and Solancler. PI. IV., fig. 1. 



Cellaria cereoides, E. aud S., Zoophytes, 26 ; Lamouroux, P.C.E., 127 ; Tubu- 

 cellaria cereoides, McG., T.R.S.V., Nov., 1884 ; id., P.Z.V., 18. 



Zocecia ovate ; surface pitted ; tliyrostomc suhcircular, straighter helow, peri- 

 stome tliickened and turned forwards, its outer surface obscurely grooved and 

 surrounded at the hase by a raised line. 



Var. areolata (fig.) Zocecia much elongated, separated by narrow raised lines, 

 depressions or areohc on surface much elongated. 



M.C. ; M. Recent. 



The specimens which I have of the normal are very fragmentary, and, although 

 suflicient for identification, are scarcely perfect enough for figuring. The var. 

 areolata, from Muddy Creek, has the zooecia much elongated, and the pits or areohie 

 are very much elongated. It might be advisable to consider it as a distinct species, 

 but I think not. 



2. T. marginata, n.sp. PI. IV., figs. 2, 3. 



Zoa>cia ovate, flattened in front, with distinct raised margins ; surface thickly 

 covered with large, round, elevated pores ; thyrostome with the peristome thick, 

 much raised, projecting forwards at nearly a right angle, its outer surface granular. 

 No special zoojcial pore. 



S.P.; M.C. 



The zooecia are l)ordered by distinct raised margins, those of contiguous zoo?cia 

 being separated by a narrow groove. The pores are raised and tubular. In the 

 most perfect peristomes the edge is slightly expanded, everted and sinuous. 



Family Prostomariid^. 



Zoarium erect, branched. Zocecia uniserial, alternate, cylindrical, opening on 

 one aspect fm'wards and outwards, posterior surface separated from the anterior by 

 a narnjw raised line; peristome much produced.

 Characters as for the family, 



1. P. gibbericollis, n.sp. PI. III., fig. 28. 



Each zocecium arising from the posterior and lateral part of the preceding by a 

 broad base, the upper part turned forwards ; anterior surface finely punctate, with 

 small bordered pores ; thyrostome with the peristome much produced, forming a
