JOHNSON AND Hensman—A List of Irish Oorallinacee. 29 
Foslie finds it difficult to determine the exact limits of Harvey’s 
Melobesia calcarea, and considers M‘Calla’s Nullipora compressa a 
variety of the present species. 
Our specimens of L. coralloides, f. flabelligera, agree very well 
with the figures of Nullipora compressa in Johnstone’s “ British 
Sponges and Lithophytes,” and come from the same locality. The 
circumstances of the loss of the collection of specimens of Coralli- 
nacee made by M‘Calla, and utilized by Harvey for description 
and illustration in Phycologia Britannica, have recently been 
described by Dr. H. P. Wright (‘Notes from the Botanical 
School of Trinity College, Dublin, 1896”). The M‘Calla Collec- 
tion, in the charge of one of us, had the labels rewritten some time. 
before we saw it, and is unfortunately not now, to this extent, 
authentic. 
*Z.. dentatum, Kitz., with *Z. Hauckii, Fosl. (ZL. mamillosum, 
Hauck), the latter partly covered with Z. incrustans (Phil.), Fosl.

This interesting and extremely local species is still to be got 
by dredging on the coral bank in Roundstone Bay.
