DESCRIPTIONS OF NEW SPECIES. 
Lafoëa elegans, n. s. 
Hydrocaulus stout, widely branching. Stem fascicled. Ultimate branches 
pinnate, alternate.  Hydrothecæ disposed alternately, cyathiform, arising from 
branches and ultimate ramuli. Margin smooth, edge slightly everted. One 
or two annular stria. 
Gonosome unknown. 
Jarbados, 180 fms., and Barbados, 125 fms. 
Differs from LL. fruticosa in having pinnately arranged ultimate branches. 
Resembles closely L. helicioides, All., but larger. 
L. convallaria, Arr. 
A specimen. of L. convallaria bears along the stem gonosomes like those of 
Cryptolaria conferta, All. — Clarke * refers these gonophores to the Lafoéa, upon 
which they are found, as Allman does the supposed gonophores of C. conferta. 
Campanularia insignis, n. s. 
A specimen of Campanularia is found in the collection. It resembles C. 
macroscypha in having a discoid internode just below the hydrotheca. It has
