cognised it as a species •which had not uncommonly occurred to me on the 

 North-East coast, attached, in the form of minute tufts, to the stems of 

 Desmarestia aculenta, Fi(rccUariafastJfiiata, &c. I once procured it from 

 the under side of a stone in Belfast Bay. 

 Youghal, Miss Ball. 



B. imhricata, Johnston. 



Obtained around the coast of Ireland. The first time I gave any atten- 

 tion to this species, in situ, -was in Clew Bay (Co. Mayo) in July, 184.0, 

 ■when it ^vas obvious that Boicerbankia densa, which appeared in quantity 

 along -with it, was only its early state. I remarked the same in Round- 

 stone Bay soon afterwards. I Avas not aware at this time that any other 

 naturalist had come to the same conclusion. W. T. 



Genus Lagenella. 

 L. repens, Farre. 



In January, 1835, this occurred to me in Strangford Lough, but I was 

 unable to identify it with any described species. Dr. Farre's excellent 

 memoir, which appeared in the Philosophical Transactions for 1837, sup- 

 plied this want ; and since that time I have, by the examination of the 

 living polype obtained in the locality just named (and on the same species 

 of Algse as the B. densa), ascertained to a certainty its identity with 

 B. rejjens.
