NO. 3667 POLYCHAETES—BANSE AND HOBSON 3 
The annual temperature range of the shallow stations during 1964 
was 8-13° C, that of station 7 was 8-12° C, and that of the deepest 
station (2) was 8-10.5° C. The average salinity for stations 1-4, off 
Seattle, was 29.8°/o0; that for stations 5-8 in the southern Sound 
(Case Inlet) was 29.2, with very little variation. At station 8, the 
shallowest of the eight stations, the seasonal range was 28.0 to 
29.7°/oo S, and at station 2, the deepest one, it was 29.4 to 30.8°/o0S. 
The oxygen concentrations were between 58% and 87% of saturation. 
The data of 1964 were representative for other years (Lie, in press). 
Water movement near the sea bed was always noticeable at the 
stations during studies with a television camera.

Typrs.—Holotype: USNM 36273, from Station 2, 47°42/16” N, 
122°26'24’’ W (November 1963). Paratype: USNM 36274 (1, in frag- 
ments) from Station 7, 47°13’30’’ N, 122°49’36’’ W (February 1963). 
There are eight anterior and some posterior fragments from stations 
2 and 7. The holotype has 18 setigers and is 12 mm long without cirri. 
It is 7 mm wide without cirri or setae and 2.5 mm without parapodia. 
The width of a mature female (paratype, 32 setigers) is 8 and 3 mm, 
respectively. 
DescripTion.—The prostomium (fig. 1a), slightly broader than 
long, is divided by a mid-dorsal furrow, is blunt anteriorly and without 
peaks. There are two pairs of eyes, which, after two years of preser- 
vation, have disappeared in some specimens. The appendages of the 
prostomium bear scattered short filiform papillae. The antennae 
arise from large cirrophores. The median antenna of the paratype is 
as long as the tentacular cirri. The lateral antennae insert termino- 
ventrally. The styles are disproportionately thin and short compared 
with the cirrophores. The palps are about 4.5 mm long. There are 
two smooth spines in the base of each dorsal tentacular cirrus.
