Genera of the North American Palaeozoic Bryozoa. 413 



mals of Bowerhanhia imhricata^ Valkerla cuscuta, V. pustulosa, 

 Yesicularia spinosa and other allied forms. He also perceived 

 their internal relation with the compound Ascidi^, and separat 

 ing them from corals, gave to them the name, Poltzoa. Being 

 situated in a remote part of Ireland he was seemingly ignorant 

 of the previous work of Ehrenberg, Edwards and Grant. 

 Ehrenbero's papers were printed from 1828 to 1^31 (Symbolae 

 Physicae) and Thompson's in 1830. There is no date printed on 

 the title page, but according to Allman it is to be found on the 

 paper wrapper in which the publication was originally stitched. 

 It has been, and still* is a matter of dispute whether the term 

 Bryozoa of Ehrenbekg or Polyzoa. of Thompson has priority. 

 The name Bryozoa has been adopted by many English natural- 

 ists, and seems to be growing in favor among them, while it is 

 used by all the naturalists of the world, with the exception of 

 those of England and her colonies, and the use of that term will 

 probably in time become universal.
