Cyclostomutous Bryozoa (Polyzoa) from Australia. A. W. WATERS, 
F.G.S., ‘ Quart. Jour. Geol, Soc.,’ Vol. XL. (November 1884). 
After the publication of my fifth British Association Report on Fossil 
Polyzoa, 1884, the above paper was published in the ‘ Journal of the 
‘Geological Society.’ I was able, however, to refer to the reading, &c. in 
a note when correcting the proof sheets of the Report ; but as I consider 
.the paper a very important one, I make no apology for giving the follow- 
ing rather full digest, together with remarks on some of the species. Mr. 
Waters describes thirty-four species of Cyclostomata from Australia, some 
of which are new, but as he reintroduces for our consideration some of 
the—now obsolete—names of D’Orbigny and others, it may be well to 
give the full list of synonyms, &c., furnished by the author. 
As a preface to the descriptive matter of this paper, Mr. Waters 
reviews the whole of the work on Fossil Cyclostomata—very briefly, how- 
ever—of previous authors; and as some of his remarks bear upon the 
classification of the Cyclostomata, the student of both Fossil and Recent 
forms should master the special details of some of the zocecial characters 
of the group, especially those parts which refer to the size of the tubes, 
the ovicells, and also of the pores of the interspaces—cancelli. These 
details may ultimately help us to understand, more fully than we at 
present understand, the apparently homologous characters in Paleozoic, 
and in some few Mesozoic, species of Polyzoa.

I should be rather inclined to place this species in the genus Filisparsa, 
than in Orisia, bnt as Mr. Waters founds his opinion upon the classifi-
