are present at least through the twenty-second setiger, and interramal 
cirri are present from the first through at least the seventh setiger. 
The setae of the first six (sometimes seven) parapodia appear bushy, 
as in California animals (Hartman, 1961), but contrary to Hartman’s 
(1965a) description. 
New for Puget Sound. Previously known from California. 
Family SPIONIDAE 
Laonice Malmgren 
While describing a new species from Puget Sound, we found it 
necessary to study the types of Z. antarcticae Hartman and L. japo- 
nica (Moore). We add here to the original descriptions of these species. 
Laonice antarcticae Hartman 
Laonice cirrata antarcticae Hartman, 1953, p. 40; 1959, p. 378. 
Laonice antarcticae—Hartman, 1965a, p. 147. 
We consider L. cirrata antarcticae Hartman a species of its own as 
did Hartman (1965a), for the following reasons: In the two types of 
L. antarcticae (Naturhistoriska Riksmuseet, Stockholm, type no. 613), 
the dorsal sense organ reaches to about the thirteenth setiger. The 
gills start, barely visible, on the second setiger. On the fourth setiger, 
they are one-fourth as long as the notopodial postsetal lamella, and 
only on the sixth to tenth setiger do they attain the same length as the 
lamellae. In the segments immediately posterior to the gill-bearing 
region, the ridges connecting the notopodial lamellae with the dorsum 
occupy about one-fourth of the distance between the lamellae, as in 
L. pugettensis, and are otherwise inconspicuous. Hooks in the forty- 
sixth and fifty-seventh setigers have two teeth, side by side above the 
main fangs, as in Brazilian material (Hartman, 1965a). 
Laonice cirrata (Sars)? 
Our specimens differ from the European representatives as de- 
scribed by Séderstrém (1920) by having two small teeth rather than 
one, side by side above the main fangs of the ventral hooks (no 
exception in the four parapodia of two specimens studied). This is 
one of the characters by which Séderstrém distinguished his L. 
bahusiensis from L. cirrata (later authors have not separated these 
forms). According to Séderstrém, genital pouches begin with the for- 
mer species at the fifteenth to seventeenth setiger, with the latter at 
the twenty-eighth to thirty-fifth setiger. Hartmann-Schréder (1965) 
has reported Z. cirrata from Chile, with similar hooks as in our form. 
The Chilean form is clearly different from ours, as well as from 
Séderstrém’s form, because of its short dorsal sense organ, although 
the beginning of brood pouches is not known.
