could not find it. One of our specimens creeping over an 

 ascidian, however, is without this crust. 



Halecium tenellum, Hincks (PI. IX, figs. 6 and 7). 



Hincks speaks of the gonothecae of this species being 

 borne on the side of the calycle. I have found them so 

 (see fig. 7) and on the stolon, but also and most frequent- 

 ly protruding from hydrothecse in place of polypes, (as 

 shown in fig. 6). 



Flumularia echinulata, Lamarck (PI. IX, figs. 8, 9 & 10). 



I have hesitated over the specimens finally placed under 

 this name. They have the internodes of the stem narrow- 

 ing towards the base (see fig. 8), the right number of 

 nematophores in well preserved specimens, and other 

 characters of P. echinulata, but they have also, as in P. 

 similis, the branchlets set forward on the stem, never less 

 than two joints between the calycles (fig. 8), and the 

 gonothecae often without spines (fig. 10), and obscurely 

 lobed ; even when spinose (fig. 9) they are always more 

 the shape of Hinck's figures of P. swiilis than of those of 

 P. echinulata.
