[fraser] HYDROIDS OF THE VANCOUVER ISLAND REGION 137 



annulated or wavy throughout but the stolon is not annulated; hydro- 

 thecae large, somewhat urceolate although at times the sides are almost 

 straight, the base being hemispherical; the 10-12 teeth are quite 

 deep, rounded or squared off at the tip; the wall of the hydrotheca is 

 somewhat ribbed, the line so formed showing quite distinctly, running 

 from the spaces between the teeth, the full length of the hydrotheca. 



Gonosome. — Gonangia large, bottle-shaped with a long neck, 

 attached to the stolon by a very short pedicel ; surface smooth ; ova 

 very few, large. 



Distribution. — Puget Sound (Nutting) ; Port Renfrew (Fraser) ; 

 off Cape Edenshaw, Swiftsure Shoal, off Lasqueti I., Northumberland 

 Channel, off Matia I., off Sucia Is., off O'Neale I., Friday Harbor.

Trophosome. — Stems unbranched forming the pedicels for the 

 hydranths, arising from a stoloniferous network; the pedicels are long 

 and slender, varying much in the amount of the annulation; there is 

 always one clear cut annulation, accompanied by two or three others 

 less deep at the base of the hydrotheca; hydrotheca rather small, 

 tapering gradually from margin to base; margin entire. 



Gonosome.— Gonangi urn large, deeply corrugated, each corrugation 

 with a distinct keel, attached to the stolon by a short annulated pedical. 



Distribution. — Pt. Wilson, Pt. Townshend and Bremerton, Wash. 

 (Calkins); San Juan Archipelago (Fraser); off Round I. in Dodds 

 Narrows, Gabriola Pass, off Waldron I. 



? Campanularia longitheca new species* 



PI. XI, Fig. 32 

 Trophosome. — Stems unbranched serving as the pedicels for the 

 hydranths; pedicels long and slender, with several annulations at 



*Note. — Since the manuscript of this paper was sent to the press, the gonosome 

 of this species has been obtained and in consequence it is necessary to place it, not 

 in the genus Campanularia, but in the genus Clytia, as Clytia longitheca. 



The gonangium is attached to the stolon by a short pedicel with three annula- 

 tions. It is rather long and slender, 1.25 mm. in length and . 3 mm. in greatest 

 width. The base is narrow and from this the gonangium gradually increases in size 

 for the proximal third of the length, after which it is practically uniform. The dis- 

 tal end is sharply truncate, with the opening occupying less than one-third of the 

 surface. The walls are smooth. In the specimens obtained there were five medusa? 

 in each gonangium. 



The specimens were dredged in 15 fathoms at the entrance to Nanoose Bay.
