indents the square tops of the teeth ; and in the shape of the 

 hydrotheca, which, instead of forming a cylinder rounded at the 

 base, resembles more an inverted cone, for the sides slope 

 gradually from the mouth where the dianieler is greatest to the 

 point of junction with the stalk. In these respects, as well as in 

 the less marked development of the diaphragm at the base of the 

 hydrotheca, our specimens' agree with var. grandis, obtained by 

 the "Talisman" in the Gulf of Cadiz, and described by Billard, 

 and to that variety we accordingly assign them. 



Dimensions. — 



Stalk, length up to 3"5 mm. 



diameter 0-057-0-096 mm. 



Hydrotheca, depth 0-91-0-98mm. 



,, diameter at mouth ... 0*38-0-49 mm. 



Remarks. — Campanularia hincksii, var. grandis, is a variety 

 which approaches the Antarctic species, Campanularia laevis, 

 originally described Vjy Hartlaub. The dimensions of the latter, 

 however, are gigantic compared with those of this Australian 

 form. 1 



Localities. — Growing on Sertrdarella divaricata, var. subdicho- 

 toma, from Station 44, off Coogee, five to six miles from shore ; 

 depth, 49 to 50 fathoms; bottom, fine sand ; 15th. March, 1898 

 — rare. Also on a Polyzoon (without Station number), New 

 South Wales. 



Ganipamdaria hincksii has been recorded frequently from the 

 eastern waters of the North Atlantic Ocean, from Norway to the 

 south of Madeira ; less frequently from the western portion of 

 the North Atlantic (by Verrill and Nutting), while records by 

 Torrey alone tell of its presence on the west of North America. 

 Broch says of it: — "Die Art scheint ihre Hauptverbreitung in 

 den subarktischen Teilen des Atlantischen Ozeans zu haben."® 

 So far as I am aware, the. species has not hitherto been recorded 

 from the Southern Hemisphere. . . . ; ■
