[fraserI HVDROIDS OF THE VANCOUVER ISLAND REGION 139 



tions or with one or two; hydrothecae very large reaching a length 

 of 3-5 mm. and a breadth of 1-25 mm., almost tubular in some cases 

 but more urceolate in others; margin slightly everted and slightly 

 sinuous, the sinuosities being wide but very shallow; reduplication 

 of the margin often takes place; hydranth with 18-20 tentacles. 



Gonosome. — (Not previously described). Gonangium large but 

 not so, relatively to the hydrotheca; it is about 2/3 the length and 

 2/3 the diameter of the hydrotheca; it is deeply corrugated, each 

 corrugation being provided with a keel. It resembles the gonangium 

 of C. intégra but is much larger. 



Distribution. — Off Matia I., off Sucia I., very plentiful in some 

 Friday Harbor material.

Trophosome. — Stems unbranched serving as pedicels, arising from 

 an annulated stolon; the pedicels are also annulated throughout, 

 they are short as compared with the length of the hydrothecae and may 

 be shorter than they are; hydrothecae large although not nearly so 

 large as those of C. regia, reaching a height of 2 mm., urceolate; margin 

 rather undulated than toothed as the tooth is low and rounded; teeth 

 10-12 in number; from the teeth lines run down the wall of the 

 hydrotheca for some distance but they cannot be traced more than 

 one-third of the distance to the base. 



Gonosome. — Gonangium shaped like an inverted cone, except 

 that the sides are somewhat curved; the height and greatest width 

 are nearly equal; the pedicel is very short. 



Distribution. — Friday Harbor (Fraser) ; off Massett, Gabriola 

 Pass, off Matia I. 



I have already called attention 18 to the great resemblance between 

 the trophosome of this species and that of C. magnifica Fraser, although 

 the gonosome is very different in the two species. Levinsen gave a 

 correct description and figure of the gonosome of this species but since 

 the paper referring to this matter was written and before it was 

 published, Broch, having found C. magnifica supposed it to be C. 

 speciosa and stated that Levinsen's gonangium was not fully de-
