Disoma multisetosum.—Hartman, 1959, p. 394. 
Trochochaeta multisetosa.—Pettibone, 1963, p. 312. 
There is one incomplete specimen from station 2. The dorsal 
postsetal lip of the third setiger is strongly digitate (fig. 6g); on the 
undissected animal, the uppermost lobe of the lip protrudes like a 
cirrus, which is not so on the preceding and following parapodia. 
There is no acicula in the notopodium. The shape of the notopodial 
lamella on the third setiger is very close to that drawn by Friedrich 
(19388, fig. 88b) from material close to the type-locality. We therefore 
assign the specimen to 7. multisetosa rather than to T. franciscanus 
(Hartman). A detailed comparison of better preserved material 
from Puget Sound with the description of 7. franciscanus by Hartman 
(1947b) would be desirable. Trochochaeta franciscanus is considered 
a synonym of 7. multisetosa by Pettibone (1963). 
New for Puget Sound. Previously known in the Pacific from 
Sakhalin. 
Family CirRATULIDAE 
Caulleriella alata (Southern)? 
Because of the differences in the insertion of the palps and in the 
setation, we have some doubt that our animals are identical with the 
European C. alata (Southern), but we do not wish to decide on this 
before having studied material from other localities on the west coast 
of the Americas. As in C. viridis pacifica (Berkeley), the palps insert 
on the first setiger rather than on the preceding segment. Caulleriella 
viridis pacifica is considered a synonym of C. alata (Berkeley and 
Berkeley, 1950). In the first neuropods of our animals are 8 to 10 
winged, bifid hooks and 1 to 2 capillary setae in small and large 
specimens (about 2-3 mm long, with 0.4-0.5 mm greatest width, and 
1-1.5 mm long and 0.6-0.8 mm greatest width, respectively). Capillary 
setae can be absent in posterior neuropodia. Notopodial hooks are 
found from the forty-fifth to fifty-fifth setigers on, rather than from 
about the twentieth as in the European representatives (Southern, 
1914). Notopodial hooks from the twentieth setiger have also been 
reported for C. alata from southern California (Hartman, 1961). 
Hartmann-Schréder (1962) has recorded hooks starting from the sixth 
and the seventeenth notopodia in Chilean material. Our form 1s 
certainly different from C. alata maculata (Annenkova).
