with her conclusion. Since all setae are com¬ 
posite (or presumably so), and dorsal cirri are 
articulate, it is herewith referred to Typosyllis. 
Setae are few in parapodia. Anteriorly there are 
about 12 in a parapodium; the dorsal one to 
three often lack their appendage, thus resem¬ 
bling simple setae, but this lack is believed to 
be due to loss through wear. Posteriorly each 
parapodium has only about six setae, and the 
dorsal ones similarly lack a distal appendage. 
In anterior segments the superior setae are 
slender and have longer appendages than those 
in the inferior part of the fascicle, or those in 
median and posterior segments. Their tips are 
bidentate, with an accessory tooth that is very 
slender and long; when worn, such setae appear 
to have an entire tip. The cutting edge has a 
row of fine spines; the outer side of the shaft 
has a few fine spines at its thickened portion. 
True ypsiloid (simple) setae are lacking (see 
also Berkeley, 1938: 41). In far posterior seg¬ 
ments, the setae are similar to those in median 
segments but more slender. In all setae the 
articulation tends to be incomplete. 
T. elongata differs from T. alternata (see 
above) in that the setal articulation is incom¬ 
plete in the former, complete in the latter; the 
appendage of anterior setae is shorter in the 
first than in the second; the superior seta 
often resembles an ypsiloid one in the first, 
whereas it retains its appendage in the second. 
T. elongata was originally described from Wash¬ 
ington south to California but has since been 
reported from various parts of the northeast 
Pacific (see synonymy above). The present 
records are from southern Alaska to the Pribilof 
Islands in the Bering Sea, from shore to 125 fm.

PACIFIC SCIENCE, Vol. II, January, 1948 
Originally described from Greenland, this 
species has been reported from cosmopolitan 
areas, especially in boreal and arctic seas. The 
present records are from Leonard Harbor in 
20 to 25 fm., Cold Bay in 15 to 35 fm., and 
northwest side of Bare Island, in 13 to 15 fm. 
Typosyllis pulchra (Berkeley)

Typosyllis pulchra Hartman, 1944: 250. 
Collection. Station 108-40 (3). 
This species is pigmented chocolate brown 
dorsally. Composite setae have entire tips. 
Originally described from western Canada, it 
has been found in central California (Hartman, 
1944: 250). The present record is Alitak Bay, 
shore. 
Typosyllis stewarti (Berkeley) 
new combination 
Syllis stewarti Berkeley, 1942: 191. 
Collection. Station 108-40 (1). 
A single large, much-coiled individual has a 
strongly arched dorsum; it is chocolate brown 
above, pale below; cirri and antennae are also 
pale. Antennae and dorsal cirri are short but 
distinctly moniliform. The median prostomial 
antenna is inserted far back at the posterior 
margin of the prostomium. Parapodia are in¬ 
conspicuous though fleshy; there are about five 
yellow acicula in each; they terminate distally 
in a blunt tip. Setae are composite and of a 
single kind; therefore, the species is considered 
a Typosyllis. The appendage is short and fal- 
cigerous; it has a smooth tip and the cutting 
edge has a few long spines. The uppermost ones 
resemble those below. Anterior setae resemble 
those in posterior and median segments but 
those in the middle of the body are thicker and 
larger than those elsewhere. 
T. stewarti has heretofore been known only 
through a single individual from Vancouver 
Island, Canada (Berkeley, 1942); the present 
record is Alitak Bay, shore.
