DESCRIPTIONS OF NEW SPECIES. 



Lafoea elegans, n. s. 



Hydrocaulus stout, widely branching. Stem fascicled. Ultimate branches 

 pinnate, alternate. Hydrothecsa disposed alternately, cyathiform, arising from 

 branches and ultimate ramuli. Margin smooth, edge slightly everted. One 

 or two annular strise. 



Gonosome unknown. 



Barbados, 180 fms., and Barbados, 125 fms. 



Differs from L. fruticosa in having pinnately arranged ultimate branches. 

 Resembles closely L. helicioides, All., but larger. 



L. convallaria, All. 



A specimen of L. convallaria bears along the stem gonosomes like those of 

 Cryptolaria conferta, All. Clarke* refers these gonophores to the Lafoea, upon 

 which they are found, as AUman does the supposed gonophores of C. conferta. 



Gampanularia insignis, n. s. 



A specimen of Gampanularia is found in the collection. It resembles C 

 nuicroscypha in having a discoid intemode just below the hydrotheca. It has
