A. W. WATEKS ON CHELOSTOMAIOUS BKYOZOA FROM 



by general appearance when the two most important characters are 

 utterly different. 



Mr. Busk frequently refers to the enlarged ooecial cells without 

 giving figures, which is much to be regretted, as such cells are not 

 always to be found, and in no species of Adeonella have I ever seen 

 any. In A. jpolystomella the border cells are slightly larger and have 

 but seldom an avicularium, and in many Cretaceous fossils with an 

 Escharine growth the border cells are frequently larger than the 

 central ones without there being reason to suppose that they are 

 modified cells. The finding of a polypide {he. cit. p. 178) in an ovicell 

 is so entirely at variance vtdth all our previous conceptions, that we 

 should have been glad to have had fuller particulars and figures. 



The collection here described furnishes 73 species, of which 46 are 

 known liviiig, bringing the number of Australian fossil Bryozoa de- 

 scribed u]3 to 220, of which just about half have been found living.
