I have been so unfortunate as never to obtain Laomedea gelatinosa with an 

 even rim, though I have them from four fathoms Southwold, thirty-five fathoms off the 

 Tees, thirty-five fathoms Copinstra, and four fathoms Kirkwall Bay, Orkneys. The 

 cells of Campanularia volubilis, as drawn by Van Beneden, are exact representations 

 of the crenatures. Before seeing his Memoir I had sketched the outline of these 

 cells, which might now be taken for copies of his figures." — F. W. L. Thomas, Lieut. 

 R.N. in Letter of 25 April, 1846. 



It would appear, therefore, that two species are confounded under the name of 

 Laomedea gelatinosa ; and, when their characters are defined, the name ought to be 

 restricted to that with crenated cells. See page 106.
