THE COLLECTTON OF MISS H. GA.TTT. 133 



minable in the dried specimen, the reference of this remarkable 

 little Campanularian to the genus Campanularia is of course only 

 provisional. 



The specimen was brought by Dr. Harvey from New Zealand, 

 where it occurred growing over the surface of a seaweed, Melaii- 

 thalia abscissa. 



Seettjlarella. 



Sertulaeella maegaeitacea, n. sp. (PI, YII. figs. 3, 4.) 



Trophosome. — Stem monosiphonic, much branched. Hydro- 

 thecse distant, adnate by about half their height to the stem, from 

 which they then become strongly divergent, epicauline side ven- 

 tricose towards the base ; orifice with a thickened rim and with 

 a deep sinus at its apocauline side. 



Gonosome. — Gronangia springing from the angles of the rami- 

 fication, ovoid, marked by wide transverse rugse towards the 

 summit and the base. 



Locality. Straits of Magellan. On an air-vesicle of Macro- 

 cystis pyrifera. 



This is a delicate form, attaining a height of about 3 inches, 

 with a very thin pellucid periderm. The gonangium develops 

 an acrocyst, the remains of which are visible in the specimen. 



Seetulaeella capillaeis, n. sp. (PL VIII. figs. 1-3.) 



Trophosome. — Stem monosiphonic, very slender, much branched, 

 branches giving ofi" pinnafcely disposed alternate ramuli. Hydro- 

 thecse adnate to the internode for about half their height, then 

 becoming free and abruptly divergent; orifice wdth two very 

 narrow teeth posteriorly and two broader teeth anteriorly. 



Gonosome. — Gronangia springing each from a point just below 

 a hydro theca, pyriform, surrounded throughout their whole 

 length by prominent annular ridges, opening on the summit by 

 a central, scarcely elevated orifice. 



Locality. New Zealand. 



This species attains a height of about 3 inches, and comes 

 near to the Sertularella Johnsoni of Grray, which it closely 

 resembles in habit. It differs from it in the abrupt divergence 

 of the free portion of the hydrothecae and in the pyriform 

 gonangia. 



Seetulaeella ceassipes, n. sp. (PI. VIII. figs. 4, 5.) 

 Trophosome. — Main stem strongly fascicled, very thick, sending 

 off a few fascicled branches, from which and from the main stem
