COKALS AND BRYOZOA. 23 



ing in regular clavate internodes, each o£ which sends off a small 

 branch. Lines of tubes distinctly marked. Whole surface 

 closely punctate. 



There is sufficient definitcness of character in this form to 

 warrant its separation as a species. E. haastiatia (Stol.) is very 

 distinct from tliis^ the orifices being quincuncial. App. Off. 

 Cat.j p. 37, No. 37. Shakespeare Cliff (lower part)^ Wanganui ; 

 III. Fig. 23, branch magnified. 



Genus — Spiroporina. Stolickza (Reise d. "Novara," Geol. 

 Theil., Iste Band, p. 103). 



Zooarium calcareous, branched ; branches cylindrical ; cells 

 tubular ; orifices disposed in rings at intervals, encircled by a 

 raised ring ; surface porous ', centre of the branches spongy, 

 with cells and minute tubes. 



Spiroporina vertebralis. (Stol., loc. cit., p. 106, and plate, 

 figs. 6, 7.) This species is well represented in New Zealand, as 

 there are a great many specimens in the collection. It is equally 

 common in tlic Mount Gambler, South Australian, limestones ; 

 in the Table Cape beds, Tasmania ; Muddy Creek, Victoria ; 

 and Cape Otway beds. It was described by me, under the name 

 of PustuUpora ungidata, in the Proc. Roy. Soc. N.S.W., 1876, 

 p. 150. App. Off. Cat., p. 36. No. 3: Hutchison's Quarry, 

 Oamaru ; V. No. 35: Shakespeare Cliff (lower part), Wanganui ; 

 III. No. 54 : coralline limestone, Raglan ; Y. 



Spiroporixa immersa, n. s. Zooarium with bifurcating 

 cylindrical branches. Cells in somewhat inclined circles. Mouth 

 with a raised pyriform margin, which is notched in front ; an 

 inner margin surrounding an oval orifice. 



One specimen from Wanganui is the only one I have seen. 

 It is very much like one of the mesozoic species. The genus 

 may be regarded as mesozoic in its affinities, and another in- 

 stance of the mesozoic character of all our Australian Tertiary 

 fossils. App. Off. Cat., p. 37, No. 35. Shakespeare Cliff 

 (lower part), Wanganui; III. Fig. 24 — A, branch, slightly 

 magnified ; B, cells, much magnified. 



Genus — Fungella. Hagenow. 

 Zooarium pedunculate, capitate, simple or divided into lobes, 

 the contiguous tubes opening on the upjier surface. 



Fungella lobata, n. s. Zooarium broadly pedunculate,
