The sub-kingdom Coelenterata has not yet been acknowledged as 

 such in the writings of several Zoologists. Some have endeavoured to 

 convince themselves of its supposed unsuitability. Others, and these 

 the greater number, slow to appreciate the facts and arguments 

 brought forward by recent enquirers or, it may be, unduly impressed 

 with the belief that all classification is, at best, but provisional, have 

 rejected it, less from conviction, than from an indolent or prejudiced 

 adherence to the systems usually adopted in the older treatises on 

 Zoology. 



The Reviewer, therefore, proposes to take a brief survey of the 

 leading views which, during the present century, have prevailed 

 with reference to the systematic relations of the animal forms in 

 question. A knowledge of such views, in itself sufficiently desirable, 

 becomes necessary for those who wish to consult, with ease and ad- 

 vantage, the numerous memoirs which have, from time to time, treated 

 of Ccelenterate organisms, under whatsoever designation.
