shew a tendency to become club-shaped. They are densely 

 crowded both in the tentacles and body- wall, and are nearly all 

 arranged in a direction parallel with the long axis of the zooid. 



The species seems to be most closely related to Clavularia 

 pacifica (Kiikenthal, 1913, p. 237) from the coast of California, 

 previously described by Nutting (1909, p. 686) as Sympodiuiin 

 armatum. This species, however, differs from Clavtdaria moresbii 

 in having stouter and more retractile zooids (5 mm. x 2 mm.), 

 with eight deep longitudinal grooves and larger .spicules (0'25- 

 0*3 mm. in length). The spicules, moreover, are much more 

 crowded together in Clavularia moreshii, a.nd do not show in such 

 marked degree as in G. pacifica a transverse disposition at the 

 base of the tentacles, and I cannot find in my preparations any 

 spicules that by becoming thickened at one end show a tendency 

 to be club-shaped. 



In Clavularia eburnea (Kiikeiithal, 1906, p. 14) from Japanese 

 waters the zooids are larger (12 nun.), but in the spicula.r 

 armature and in other characters C. eharnea is more closely 

 related to C. jiacifica than it is to C. moresbii. 



But, although the relationship of our new species with the 

 Calif ornian species C. pacifijca is pronounced, it must be pointed 

 out that its relationship with some of the Norwegian species, such 

 as C. horealis of Keren and Danielssen (1883, pi. i.), may be as 

 close, and it afibrds therefore no special reason for regarding 

 the fauna of British Columbia as being more closely related 

 to the Pacific than to the N. Atlantic fauna.

In Wilkens' edition of Pallas' ' Elenchus Zoophytorum ' there 

 is a. long accoiurt of this species, probably copied in great measure 

 from the writings of Koelreuter (1761). There can be no doubt 

 from this that the Alcyoniimi arhoreum of Linnaeus and Pallas 

 is the same species as the common species of the Norwegian 

 fjords, now known as Paragorgia arborea.
