CORALS AND BRYOZOA. 27 



cylindrical axis, opening to a surface of nearly regular hexagonal 

 facets ; avicularia immersecl_, irregular. 



Salicornaria immersa, n. s. Internodes long, slender, 

 cylindrical ; margins of cells very prominent, and lamellar ; cells 

 deeply immersed ; moutla crescentic, with a simple semicircular 

 crescentic lip, an oval or a round pore above, and another at 

 the base of the cells. The mouth of the species distinguishes. 

 it from any of those described, besides the immersed cells and 

 the raised margin. There is only one specimen in the collec- 

 tion, and this is in remarkable contrast to the Australian 

 tertiaries. Other species of Salicornaria are very plentiful. 

 One of these is >S^. sinuosa (Hassal), a living species abundant 

 also in the Pliocene crag of Suffolk. App. Off. Cat., p. 37, 

 No. 27. Conway River, Nelson, from Leda marls ; VI. Fig. 

 27, one cell, much magnified. 



Genus — Vincularia. Defrance, 1829. 



Like Salicornaria ; but the branches rigid, not articulate. 



Vincularia maorica. (Stolickza, loc. cit., p. 153, pi. 20, 

 fig. 8.) I believe this fossil is also found in the Mount Gambler 

 tertiaries. App. Off. Cat., p. 36, No. 13. Hutchison's Quarry, 

 Oamaru; \. 



Genus — Cellaria. Ellis and Solander, 1787. 



Zooarium erect, calcareous, ramose, articulate; articulations 

 fibrous, flexible ; branches cylindrical ; cells urceolate, decum- 

 bent ; orifices subtubular or roundly marginate, with or without 

 accessory pores. 



This genus has been so variously described by different authors 

 that it is worth while to quote the synonymy according to 

 Stolickza, who has given a very exhaustive essay on the much- 

 confused and difficult subject of Bryozoan nomenclature^' : —
