ON FOSSIL POLYZOA. 105 



Genus Bugula, Oken. 



There has been a variety of names for species of this genus, the most 

 distinctive of which are Ornithopora and Ornithoporiiia, D'Orb. ' Pal. Fr.,' 

 and Acliamarclvis, Lamx. 



' Zoarium erect, phytoid. Zocecia boat-shaped or subquadrangular, 

 elongate, united in two or more series; aperture occupying a large pro- 

 portion (occasionally the whole) of the front, not turned upwards or 

 oblique. Avicularia in the form of a bird's head, pedunculate and 

 jointed, usually one on each cell.' — Hincks, 'Brit. Mar. Pol.' p. 73, and 

 for synonyms, &c. 



21. Bugula turbinate, Alder. = Cellularia avicularia, Pallas. Scotch 

 Glacial beds, Duntroon. 



Genus Beania, Johnston. 

 No fossil representatives known to me. 



Family V. NoTAMIIDa;, Hincks. 

 Genus Notamia, Fleming. 

 No fossil representatives known to me. 



Family VI. Flustrid.e, Smitt. 



In the placement of this family I have put it before rather than after 

 Cellaeiid.-e — Fam. VI. of Hincks — more for convenience sake than for 

 the desire of alteration by any suggestive change. The Flustridje is 

 Fam. VII. of Hincks, but as my real work upon fossil species will begin 

 with the Cellariid*, and as I have no record of fossil forms which 

 belong to this family consisting of a single genus, Flustra, Linn., I wished 

 to prevent a further break in what will follow. 



(CatenicellidjE, Busk — ' Crag Polyzoa.') 



Mr. A. W. Waters, in his papers on 'Australian Fossil Bryozoa,' has 

 given a list, with details and descriptions, of sixteen species of fossil 

 Gatenicella, but as the classificatory position of this group is not as yet 

 decided upon, I can do no more than give the names of the various 

 species and then refer the reader to the papers of the author, already 

 fully referred to in this Report. In the paper on 'Fossil Bryozoa,' &c, 

 ' Quart. Jour. Geol. Soc' 1883, Mr. Waters has given diagrams of the 

 'globolus' of Gatenicella and the names of the various morphological 

 structures. The following are the species of Mr. Waters which he 

 considers as new : —
