Family PECTINARIIDAE 
Pectinaria (Cistenides) granulata (Linné) 
Pectinaria granulata.—Pettibone, 1954, p. 312. 
Pectinaria brevicoma.—Berkeley and Berkeley, 1952, p. 106. 
We follow Pettibone (1954) and include P. brevicoma Johnson de- 
scribed from Puget Sound in P. granulata because of the variability of 
some characters used for separation of the species. In our animals there 
are 10-11 pairs of brassy cephalic spines, about 20-40 papillae on the 
antennal membrane, and 5-7 scaphal hooks. The uncini have three to 
four major teeth. 
In small specimens, there can occur on one torus uncini with one 
row of major teeth, as typical for the subgenus Cistenides, and uncini 
with a double row, as in the subgenus Pectinaria. The large specimens 
all have a single series of major teeth in their uncini. Moore (1923) has 
stated that ‘this species unites Pectinaria and Cistenides.” 
Family AMPHARETIDAE 
Ampharete acutifrons (Grube) 
The tentacles of our specimens are smooth contrary to the generic 
diagnosis by Malmgren (1866) and Day (1964). Mature females are 
about 15 mm long and 1 mm thick but there are two broken specimens, 
otherwise very well preserved, that are at least 20 mm long and 2.5 
mm thick, and apparently are not mature. Pettibone (1954) has stated 
a length of 55 mm and a width of 8 mm as the greatest size for the 
species. The species is a selective deposit feeder, as seen from the 
comparison of intestinal content with the sediment of the habitat. 
There are animals from all seasons. Many specimens collected in 
August and one found in May carry fairly numerous oval-lens-shaped 
egos, up to 240u x 200 x 50u in size. 
Ampharete gagarae Ushakov 
Ampharete arctica gagarae.— Ushakov, 1955, p. 369. 
In this form, which we consider to be a species of its own, the 
neuropodial lappets of the middle region of the abdomen are about 
one-fourth as long as the segments, whereas they are nearly as long as 
the segments in one specimen of A. arctica from Puget Sound. No anal 
cirri were found even in well-preserved animals. The species is a 
selective deposit feeder. 
Very few (50-100) irregular oval-lens-shaped eggs of about 220u x 
1904 x 504-70» dimensions are observed in one specimen collected in 
January.
