362 vine: classifications of cyclostomatous polyzoa. 
Hagenow, and Haime, so that I shall have now — which I did not at 
one time have — available material for the purpose of instituting 
comparisons between the British and the Foreign species. After 
Haime Professor Brauns"" able paper on Jurassic Bryozoa found in 
the neighbourhood of Metz, is a valuable addition to Jurassic 
Polyzoa literature. Then four papers by myself — 1, Notes on the 
Family Diastoporidae. Quart. Jour. Geol. Soc, Aug. 1881, pp 381- 
390 ; 2, Brit. Assoc. Report on Fossil Polyzoa, Jurassic species, 
British Area only. Brit. Assoc. Rep., 1882-3. 3, Notes on Polyzoa 
found in the Boring at Richmond. Quar. Jour. Geol. Soc, Nov. 1884. 
4, Jurassic Polyzoa in the neighbourhood of Northampton ; Journ. of 
the Northampton Nat. Hist. Soc, 1886. There is also a paper on 
Jurassic species,by F.D. Longe,F.G.S.,on the Relation of the Escharoid 
Forms of Oolitic Polyzoa, &c. Geo. Mag., 1881. Besides these 
there are scattered remarks in species found in papers by authors 
when describing Polyzoa from other horizons which will be referred 
to in passing 
I have already indicated the leading ideas of Mr. A. W. Waters, 
in his several papers on Australian Tertiary Bryozoa ; and in my 
future studies of this interesting gToup of fossils, I shall note — if 
there be any to note — peculiarities of structure indicated, viz., the 
" closure," puncturing of the cells, growth, and arrangement of the 
cells in the colony. 
I shall be glad of any help that can be given to me by collections 
in this labour of love ; and I hope that much of the material that 
is hidden away in cabinets will be brought to light, and made 
available to the students of British Jurassic Polyzoa.
