knowledge, to appear first in the south-west province, and it is also 

 found in the north-east one. It is an interesting question to decide 

 whether it is continued all along the west, north-west, and north coast. 

 I am pretty certain it does not occur — though all negative testimony 

 must be received with caution — in the east or south provinces. Plate 

 xvm. is from drawings kindly lent me for the purpose by my esteemed 

 friend, P. H. Gosse, P. E. S. 



Corynactis heterocera. (W. Thompson.) 



This well-marked species occurred sparingly at Crookhaven, of 

 a pale : yellow colour, adhering to the smooth surface of large stones. 

 Anything more like a miniature crown can hardly be imagined than 

 this species when expanded, the outer row of tentacles, as so well 

 described by its discoverer, lying down, forming an acute angle with 

 the disk. It would appear to be a rare species, but would at the same 

 time be very easily overlooked, as it can assume an almost transparent 

 appearance, which makes it very difficult to be perceived. It does not 

 appear to be so gregarious in its habits as C. Allmanni, and, although I 

 looked carefully for it, I did not find it in any other locality. 



Ilyanthus Scoticus. (Fortes.) 

 Of this, the only detached Anemone that I find recorded as Irish, 

 one specimen was found by Mrs. Hancock, in 1843, on the beach at 

 Balbriggan, county of Dublin, after a storm. I have never seen a spe- 

 cimen. 



ZoANTHnLE. 



Zoanthus Conchii. (Johnston.) 

 Of this species I know nothing personally. It has been dredged in 

 Strangford Lough, so long since as 1835, by the late Mr. W. Thompson, 

 and again, in 1846, by Mr. G. C. Hyndman. It was found adhering to 

 dead specimens of Tapes aurea, &c. The English habitat is the most 

 southern parts of Cornwall. 



TuBBINOLIADiE. 



Turlinolia milletiana. (Defranc.) 

 This species has been dredged alive off the Isles of Arran, Galway 

 Bay, by Mr. Barlee. I hope that in the exploration of this Bay next 

 summer, the Dredging Committee will be fortunate enough to come across 

 this interesting Madrepore.
