NOTES ON THE POLYZOA AND FOEAMINIFEEA OF THE CAMBRIDGE 
GREENSAND. (COPROLITE BEDS OF BRITISH AUTHORS. 
CENOMANIEN (?) FOREIGN AUTHORS). BY GEORGE ROBERT 
VINE. 
The Polyzoa of the British Neocomian rocks are a peculiar 
group of fossils. Many of them appear to be related to species 
described by Goldfuss, D'Orbigny, and Hagenow, and are referred 
to as such in the works of Morris, PhilHps, and others. The existing 
material, however, has only been partially worked, and the 
references given cannot always be accurately verified when the British 
specimens are compared with the foreign forms of a similar horizon. 
The same remarks will apply to species in the Upper Greensand 
of Warminster as well as other Greensand localities. On the other 
hand, much of the material that passed through the hands of 
Mr. Lonsdale seems to have been fairly described and well illus- 
trated.* Mantell also describes — rather poorly though — a few 
Chalk Polyzoa in his various works, but since then much good 
material has been accumulating in the cabinets of collectors, and the 
whole of this early work may be consistently re-edited. In my 
fourth British Association Report on Fossil Polyzoa, 1883, I gave a 
resume of what had been done by different authors ; described new, 
and some apparently well-known Cretaceous Polyzoa ; and to the 
best of my ability, furnished special details of all the forms that I 
had access to, or that were in my own cabinet. At the time I wrote 
Greensand Polyzoa . of the Cambridge horizon were not known to 
exist, and it was only after the publication of ni}^ paper^" Notes on 
some Cretaceous Lichenoporidas (Quart. Jour. Geol. Soc, Nov., 
1884) — that the species forming the subject of the present Memoir 
were brought to light. There is no mention of Cambridge Green- 
sand Polyzoa in the Cretaceous catalogue of the School of Mines, 
neither are Br^^ozoa or Polyzoa referred to in the elaborate lists of 
Cambridge fossils appended to Mr. A. J. Jukes-Brown's paper ,
