Editorial Note. — At p. 711 Mr. Clark refers to a notice in 

 "L'Institut" of ISio, p. 292, of the discovery of anew Encrinite 

 at Newcastle, N.S. Wales, by the Rev. " C. PleydelJ." Whilst

 came upon the original reference. The clergyman referred to 

 was the Rev. " C. Pleydell N. Wilton," of Newcastle, and his 

 paper, under the title of — " On a New Species of Encrinite

 is clearly an exti'act, was published in the " Tasnianian Journal 

 of Natural Science," 1843, ii.. No. vii., pp. 118-120. 



It is quite evident from the tenor of his paper Mr. Wilton 

 had many specimens. They weie only found on the beach or in 

 rock-pools, adhering to sea-weed, after gales, Examples of this
