[fraser] HYDROIDS OF THE VANCOUVER ISLAND REGION 127

Trophosome. — Colony growing in immense tufts which make a 

 tangled mass below but separated into long pedicels which reach out 

 of the mass above; branching very irregular; stems slightly and ir- 

 regularly annulated, somewhat swollen just below the hydranth; 

 proximal and distal tentacles nearly equal in number, 20-24. 



Gonosome. — Gonophores growing in rather long racemes, which, 

 however, seldom hang below the tentacles; each is provided with 4 

 short tentacular processes but these may be very short or almost 

 suppressed. 



Color. — Hydranths and gonophores rose color with the spadix 

 brighter; stems almost white in the distal portion but yellower in the 

 proximal portion. 



Distribution. — Port Simpson (Fraser) ; Gabriola Pass, Porlier Pass, 

 Friday Harbor. 



I have not found this species growing in such masses in this region 

 as it does at Woods Hole, South Harpswell and other places on the New 

 England coast but the individuals are just as large and the proximal 

 mass is just as much tangled. The specimens from Friday Harbor 

 were obtained the last of July and they were then in good condition 

 with the large clusters of gonophores present. At this time of the year, 

 much before this time in fact, the heads are all gone at Woods Hole 

 but at South Harpswell they are as fresh as ever, as recorded in a 

 former paper. 12 



The temperature of the water and the lack of contamination at the 

 Friday Harbor localities, corresponds more nearly with conditions at 

 South Harpswell and it may be that these have something to do with 

 the continued active period.

Trophosome. — Stem usually unbranched^ reaching a height of 

 40-50 mm.; there are few annulations but these are usually very 

 distinct; stem slender at the base, rapidly increasing in size proximally 

 and more slowly distally towards the hydranth; proximal tentacles
