This Coralline is about two inches high, very Hea- 

 der, and of a bright yellow color. It creeps on fucus's. 

 The ovaries differ from all the reft of the genus : they are 

 lobated, and the lobes are placed opposite to one another: 

 thefe appear to be full of fpawn, of a deep orange color, 

 which is fent forth from holes at the end ot the lobes. 



This was firft difcovered by Mr. John Evans, a fea- 

 officer in the Eaft-India Company's fervice, among fome 

 fea productions brought from Yarmouth, in Norfolk, in 

 the year 1767.

 judge of the ftalks and imperfect pieces, not un'ike the
