Zoology.'] NATURAL HISTORY OF VICTORIA. \Polyzoa. 



PaUontologie Frangaise are either sub cylindrical or compressed and 

 ramose. In the Crag Polyzoa, Busk adopts the genus and describes 

 and figures B. delicatula from fossil specimens from the Crag, and 

 recent ones from Australia. I believe the genus to be a good 

 one, excluding, however, many forms referred to it by D'Orbigny. 

 Lamarck's Eschara chartacea is probably one or both of the species 

 here described. 



The specimens and descriptions of the above species are from 

 Mr. MacGillivray. 



Frederick McCoy.
