Campanularia magnifica new species. 

 Plate XI, figs. 1-3. 



Trophosome. Colonies consisting of solitary individuals grow- 

 ing from a stout stolon which is not annulated but may be slightly 

 sinuous. The hydrothecae are very large, as much as 2 -5mm. 

 in length and. with greatest width about 0-8mm. They are 

 nearly tubular with a tendency to be slightly urceolate. The 

 margin is slightly flaring, is crenulated with 10 or 12 elevations 

 and depressions. A series of parallel lines pass down vertically 

 from the margin for about one-third the length of the hydrotheca. 

 The pedicels vary much in length but never exceed twice the 

 length of the hydrotheca. They are annulated throughout. 



Gonosome. The gonangia are very large also. The male and 

 female are similar in size and shape, somewhat longer than 

 the hydrothecae and also broader at the greatest diameter. 

 The gonangium is supported on a very short pedicel, is almost 

 oval in shape except that the distal end is drawn out into a 

 long bottle-neck. The aperture is circular, occupying the 

 whole of the distal end. A few corrugations, low and not 

 very noticeable, are present on the broad proximal portion. 



Distribution. Several specimens, in close company with 

 Halecium tenellum, attached to a stalked ascidian, were brought 

 up by a trawl hook from a depth of 50 fathoms on the Canso 

 Banks. 



The trophosome of this species bears a great resemblance to 

 that of Campanularia speciosa Clark 1 . Prof. Nutting had 

 some of Clark's original specimens from Shumagin islands, 

 Alaska, and by using those I was able to make a comparison 

 of the two. The hydrotheca is more urceolate in C. speciosa than 

 in C. magnifica and the stolon is distinctly annulated, but in 

 other respects they are very similar; when the gonosome is 

 present there is no difficulty as the obconical gonangium of 

 C. speciosa bears little resemblance to the elongated gonangium 

 of C. magnifica. I have made a drawing of C. speciosa from a 

 Shumagin Island specimen, showing the hydrotheca and the 

 gonangium to the same scale so that the two species may be 

 compared (See Plate XI, fig. 4).
