Crisia setacea. 



Crisia cornuta. 



It is now about two years since, while examining the Zoophytes of 

 the Cornish coast, that I met with two specimens of what I then 

 thought might be varieties of the goat's horn coralline {Crisia cornuta). 

 Being, however, doubtful on the point, I pointed out the probability 

 of their being eventually found to be distinct, in the third part of the 

 ' Cornish Fauna,' which contains the Zoophytes of the county. Since 

 that time I have had the good fortune to find several other specimens 

 in Mount's Bay ; and I have also detected it among a few corallines 

 sent to me by Mr. Ralfs, from Ilfracombe. Having thus had an op- 

 portunity of examining and comparing many specimens from the 

 shores both of Devon and Cornwall, I am now enabled to point out 

 what appear to constitute the specific characters of each. 



Crisia cornuta. Calcareous, confervoid ; cells uniserial, long and 

 tubular with curved terminations all turned in one direction : 

 a long bristle above each cell. 



This is a very delicate and brittle Zoophyte ; it is calcareous, con-
